A wonderful made product. Thank you
Thank you for your kind words about our Cummins NTC / NTA / FFC 400-475 / 855 Diesel Damper. We are thrilled to hear that our product has met your expectations. Your satisfaction is our top priority and we are grateful for your support. Thank you again for choosing our product.
Finally made the decision to purchase a Vibratech Viscous Damper. In short, I wish I had done this replacement a lot sooner. This is an extremely high-quality American-made damper, and what a difference it has made. Excellent product, well worth the money!
The responsiveness of my engine has noticeably improved - the power delivery is now smoother and more consistent across the RPM spectrum. This damper is a must-have for those looking to optimize the overall performance and longevity of your Cummins engine.
I used this on a 1982 Cummins Big Cam 2 400 in a 1982 Peterbilt 359 I'm restoring. Made a tremendous difference in the vibration at idle on my rearview mirrors and much less vibration through the cab and steering wheel driving down the highway.
Great looking seems great quality! Put it on fits perfect seems to run smooth! Very happy with ordering and shipping.
