    Any product purchased with Free Shipping will not be sent out as a Priority Shipment with a guaranteed delivery time.

    If time is of the essence, we suggest you choose Federal Express as your delivery method.

    When Delivery Time Is of The Essence

    When Time Is of The Essence, and you need the product within a specific period of time, please choose either UPS or USPS Priority Express Delivery Services, as these are guaranteed delivery services. 

    KLM Performance offers multiple Express Delivery options to meet your timelines. All orders received by KLM Performance with Express Delivery Services are treated with expedited order processing times and are prepared for order shipment with the utmost urgency. In order for an Express Shipment to be processed on the same business day, your order must be received before 3:00 PM EST. Orders received after 300 PM EST will be processed on the next business day!

    Domestic Shipping Methods

    Economy or Free Shipping:

    This method does include a standard tracking number; only delivery confirmation is available. Economic or Free Shipping is the slowest shipping method and often takes six to ten business days for delivery.

    Due to recent changes in the USPS system, delivery times have now increased. If you place an order and choose the USPS as a delivery method, the shipment times are now subject to delays.

    Customers who want USPS Priority Mail must understand this is not a guarantee for delivery times.

    We reserve the right to automatically upgrade this shipping option to UPS Ground if we see fit.

    Dynamic Shipping Cost Calculation:

    Many factors determine the shipping costs incurred for orders after the checkout process.

    The calculation for shipping costs is based upon the dimensional weight of the package dimensions and weight of the products being purchased and the shipping destination and other shipping company-specific delivery options presented to the user when checking out.

    UPS Express Delivery Services:

    KLM Performance highly recommends these shipment methods when Time Is of The Essence. UPS does not guarantee these shipping methods for their stated delivery times. UPS has suspended its shipping guarantee effective March 26, 2020, until further notice. In order for an Express Shipment to be processed on the same business day, your order must be received before 3:00 PM EST. Orders received after 300 PM EST will be processed on the next business day! Please see the below link for additional information regarding the UPS policy regarding freight charge reimbursements. 


    UPS Express Saver - 3 Day Delivery Service: This shipping option will ensure delivery three business days after the order has been picked up and scanned. A tracking number will be available usually within one day of dispatch.

    UPS 2nd Day Air - 2nd Day Express Service: This shipping service will guarantee delivery within two business days after the order has been picked up and scanned. A tracking number will be available usually within one day of shipping. The cutoff for 2nd Day Air is 300 PM EST in most cases.

    UPS Priority Overnight - Next Day Delivery. The cutoff for Priority Overnight Service is 200 PM EST in most cases. Priority Overnight may not be available in all areas of the country.  If this option is not available, will the order be shipped standard overnight?  Also, it is not possible for all parts. If we cannot send it Next Day Air, but the site said it could, we will contact the buyer and let them know. A tracking number will be available usually within one day of shipping.

    UPS Priority Overnight Saturday Delivery - Our website is not configured for the Saturday Next Day Air Delivery Service method. If you need a product delivered by Express Delivery, please call in your order. Saturday delivery leads to increased fees for this service. Saturday is considered a business day for UPS shipping, but only for time-critical shipments. Regular orders are delivered Monday through Friday, and any item delivered on a Saturday must have a "Saturday Delivery" sticker on the package.

    UPS Ground Service:

    UPS Ground is our preferred method of shipping merchandise. A tracking number will be available usually within one day of shipment processing.  Although UPS does give an estimate of 3 to 5 days for delivery, they do not guarantee the purchase for delivery within that period.

    UPS Shipping Days:

    UPS shipping times are based upon the regular business days of Monday to Friday. UPS does not deliver on Saturday unless you have called in your order for UPS Priority Overnight Saturday Delivery. The KLM Performance website does not offer Saturday delivery as a suggested shipping option. Please do not include the day your package ships when calculating delivery days in transit.

    UPS Weather Delays:

    In the event of Adverse Weather your package may be delayed while in transit. Refunds for weather-related issues are considered an Act of God and do not constitute a refund for delivery services.

    USPS or U.S. Mail Shipping Methods

    USPS Priority Mail

    USPS Priority Mail - This is a low-cost alternative to express shipping. Since this is a far less expensive means of transporting your merchandise, you must understand that this is not a guaranteed means of delivery nor an Express Shipping method. Priority Mail is the United States Postal Service's standard service. Packages usually arrive at their domestic destination within 1 to 3 business days. Transit times vary depending on how far the box has to be delivered from its origin. However, it's essential to remember that this is not a guaranteed service. So, there's no recourse if packages are delayed. Recent changes within the USPS system have led to shipment delays beyond the time given on your shipping receipt. The USPS system also has issues with scanning and tracking all items shipped. Please understand that the delivery delays and scanning issues are beyond our control. USPS Priority Mail provides you with a tracking number, but it is not a guaranteed means of shipping nor an express shipping method. Scanning and delivery times are subject to the conditions that this carrier endures while your item is in transit.

    USPS Priority Mail Express

    An Overnight Delivery Guarantee backs USPS Priority Mail Express Shipping. Priority Mail Express service is the fastest domestic service provided by the USPS. There are certain limitations and exceptions to this service. For example, some overnight areas are limited to a Two-Day shipping timeline. Priority Mail Express is available 365 days a year, with a money-back guarantee and shipping to most U.S. addresses, including PO Boxes™.

    KLM Performance highly recommends the UPS Priority Mail Express method of shipment when Time Is of The Essence. In order for a USPS Priority Mail Express Shipment to be processed on the same business day, your order must be received before 3:00 PM EST. Orders received after 300 PM EST will be processed on the next business day!

    The USPS Priority mail has never been a guaranteed service and has never been offered with a money-back guarantee. Please note that the USPS Priority Mail is not an Express Service.

    You can read about the terms and conditions that govern USPS Priority Mail using this link. 


    APO/FPO Shipping (Military Address)

    KLM Performance Inc. cannot ship the product directly to APO or FPO addresses because we utilize UPS. UPS does not ship to APO/FPO addresses. As an option, you may want to consider shipping to a stateside street address and then sending the package to the APO/FPO address overseas via the US Postal Service.

    Canadian Duties & Taxes

    An international Canadian shipment recipient may be subject to import taxes, customs duties, and fees, which are levied once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid by you, the recipient; KLM Performance has no control over these charges and can't predict what they may be. Customs policies vary widely from city and province; you should contact your local customs office for more information. When customs clearance procedures are required, it can cause delays beyond our original delivery estimates. 

    Signature Requirement for Delivery:

    KLM Performance Inc. will ship almost all packages with a signature required to deliver the merchandise ordered for your protection and ours. All custom-made products require a signature for delivery.

    A signature at delivery is needed for all the main metro areas, apartment buildings, and orders over $100.

    Shipping Damage

    Please get in touch with our customer service team immediately with any concerns regarding shipping damage.

    If the item you received shows any damage, we advise you to refuse the shipment.

    You, the recipient, must notify KLM Performance within five business days of delivery receipt regarding any damage sustained to your order while in transit. 

    These items we ship are insured, and time is of the essence when filing a claim with the carrier.

    Please remember to notify KLM Performance immediately so that we can investigate this issue and pursue a response. Failure to report to KLM Performance by this timeline may affect our ability to resolve this matter and affect the claim.

    When in stock, we will replace lost or damaged merchandise as soon as we receive the appropriate claim number from the shipping company.

    Other companies execute the transportation of your merchandise; KLM Performance has no control of the item once the shipping agent picks it up.

    We are not responsible for delays, scanning, lost, stolen, or damaged packages. Shipping issues occur, and KLM Performance will make its best effort to resolve these potential problems. 


    KLM Performance can allow this to occur when the following steps are taken to ensure delivery of your order.

    NOTE: Due to Credit Card Fraud, we can No Longer Provide the Ability to Ship to any other address than the Card Holders Billing Address! If your credit card billing address is different from your shipping address, your order will default to your billing address. You must enter the correct billing address for your order as the shipping address for the order you are placing online to be processed. 


    Due to the high level of fraudulent credit/debit card activity, this policy is in place to protect you, the consumer, and we cannot make any exceptions.

    If you require an order to be sent to a different delivery address, please use PayPal for your payment method and apply this different address to your PayPal account. Log in to your PayPal account. Place your mouse's cursor over the "Profile" menu, then click "Add or Edit Street Address" on the list of options. This displays a list of your current shipping addresses. Click the "Add Address" button at the bottom of the list of addresses.

    You cannot process this decree by phone as KLM Performance no longer accepts phone order due to the actions of prior customers!  

    Additional shipping charges will be incurred for all orders delivered to an address other than the cardholder billing address. You will be required to present a Photo ID to the shipping agent for delivery.

    You must enter the correct billing address for your order as the shipping address for the order you are placing online to be processed. 

    We aren't usually handling insurance claims for damaged items, lost items, or stolen goods from your doorstep that are NOT honored by the shipping carrier because you requested a delivery without a signature.

    We will not cover the cost or be held responsible.

    For customers in Alaska, Hawaii, Puerto Rico and Canada, please consider calling in your order so we can arrange convenient shipping.

    Shipments That Require A Signature For Delivery:

    • All Custom-made orders require a direct signature for delivery.
    • All orders over $100.00 require a signature for delivery.
    • Signature at delivery is needed for all major metro areas and apartment buildings.
    • You will be required to present a Photo I.D. to the shipping agent for delivery.
    • Orders shipped with an Express Delivery Service require a signature for delivery. 
    • These measures are to help prevent fraud and ensure you obtain the items you ordered.

    Refused Shipments

    KLM Performance Order Shipments that are fused by the customer will be charged with a 25% Restocking Fee and all applicable freight charges for the return freight incurred with the return of your refused order. No credit will be issued for freight charges incurred on a Refused Order. Please make note of this condition prior to placing an order so there are no misunderstandings.

    Please feel free to contact us if you need any further information regarding the shipment of your order.



    KLM Performance Inc. applies warning labels either on our product(s), or the packaging containing our product(s) regarding CA Prop 65. This warning is part of our effort to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known as “Proposition 65”). The California Proposition 65 list now has over 800 Chemicals used in the production of goods, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.

    The warning does not mean that the products sold by KLM Performance will necessarily cause cancer, birth defects, or other reproductive harm. To comply with the requirements of Proposition 65, the following warning will be put on every product sold.

    While we believe that the products offered by KLM Performance are not harmful when used as designed, and we rely on our suppliers and manufacturers to help with this effort, we also provide these warnings to comply with Proposition 65.

    What is California Proposition 65?

    Proposition 65 is a law and applies to any company that operates in California, sells products in California, or manufactures products that may be sold in or brought into California.

    Proposition 65 requires warnings to accompany any product that contains or may contain any of the chemicals appearing on the list administered by California’s Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency.

    The current Prop 65 List can be found here: California Proposition 65 Chemical List

    Why has KLM Performance decided to provide a warning?

    Proposition 65 imposes strict penalties for noncompliance. While California establishes “safe harbor numbers” for listed chemicals, the costs of individually testing products that KLM Performance distributes is prohibitive (particularly when the list of chemicals is so expansive and subject to change on an annual basis).

    As a result of the steep penalties and because there is no penalty for providing an unnecessary warning, KLM Performance provides the Proposition 65 notice out of an abundance of caution.

    We at KLM Performance rely upon the manufacturers to clearly illustrate the warnings on their products. 

    For more information about California Proposition 65 we suggest that you review the information presented by the State Of California using this link to the the State Of California Proposition 65 Website for a full explanation regarding the STATE OF CALIFORNIA ENVIRONMENTAL PROTECTION AGENCY OFFICE OF ENVIRONMENTAL HEALTH HAZARD ASSESSMENT SAFE DRINKING WATER AND TOXIC ENFORCEMENT ACT OF 1986 CHEMICALS KNOWN TO THE STATE TO CAUSE CANCER OR REPRODUCTIVE TOXICITY

    The Safe Drinking Water and Toxic Enforcement Act of 1986 requires that the Governor revise and republish at least once per year the list of chemicals known to the State to cause cancer or reproductive toxicity.

    The identification number indicated in the following list is the Chemical Abstracts Service (CAS) Registry Number.

    No CAS number is given when several substances are presented as a single listing.

    The date refers to the initial appearance of the chemical on the list.

    For easy reference, chemicals which are shown underlined are newly added.

    Chemicals or endpoints shown in strikeout were placed on the Proposition 65 list on the date noted, and have subsequently
    been removed.
