              ARP Chevy and GMC Duramax Diesel Main Studs
              Home / ARP Chevy and GMC Duramax Diesel Main Studs

              6.6L Duramax Diesel Main Stud Kits

              The installation of the ARP Main Stud Kit on the Chevrolet and GMC vehicles with the 6.6L Duramax ensures a high performance diesel engine will not have the main caps from walking during high RPMs. These ARP Duramax Main Stud Kit will keep your engine running at its optimum performance level by reducing walking and fretting. These kits provide the improved clampdown levels required with torque specifications of 200 foot-pounds on the main bolts and 86 foot-pounds on the side bolts. 

              ARP GM Duramax Diesel Main Stud Kits are a Performance Upgrade that strengthens the lower end of your motor. Installing your Powerstroke Diesel main caps and girdle with high strength, ARP main studs offer superior protection of your motor's lower end. Remove the old weak factory hardware with ARP High-Performance Series Main Studs which are hardened to a tensile strength of 190,000 psi to provide superior strength for long-lasting performance. ARP Fasteners are ideal for high performance street and track Super Duty Trucks.

              The use of  an ARP 6.6L Duramax Diesel Main Stud Kit offers the following benefits;

              • ARP Main Studs protect the threads in your engine block.
              • Main Studs provide more accurate torque readings because main studs do not twist into the engine block.
              • Main Studs produce clamping forces that are on one axis.
              • Less force is exerted on the block threads which contributes to improved engine block life.
              • Using a precision-made main stud allows for easier engine assembly.
              • Main Studs ensure the proper aliment of the main caps.
              • Main Studs do not allow the main cap to move.
