LS-100-Kit

Manton Pushrods is proud to release a Premium Tool steel Billet Trunnion upgrade kit for the GM LS engine platform. It replaces both the cage-less OEM needle bearings and stress formed 9/16 diameter trunnions with our high load capacity bronze bushings as well as, our 3/4 diameter maximum surface area trunnions. Our improvement in design and engineering will provide more load disbursement area on the bottom side of the trunnion, where the majority of stress occurs. We have also engineered the bushing to wrap around the outside of the rocker arm body, which provides a very low co-efficiency of friction when side thrust occurs between the bushing and thrust washer (No c-clip to bushing contact can occur). Due to reduced bushing thickness we have been able to lower the rocker arms mass moment of inertia. All of these improvements will aid in extending service life and improve performance in all applications, including your daily driver.
*100% Less Needle Bearings
*Reduced Rocker arm Trunnion Harmonic Frequency Magnitude

Quality Kit

Written by Chad Lawton on Nov 23rd 2019

Really nice and quality kit from Manton Rockerarms. I recently replaced a competitors needle bearing trunnion upgrade kit with this Manton Rockerarms bronze bushing kit for LS engines and afterward my valvetrain noise was cut in half. Very impressed with the robustness and quality of this kit. They also included extra pieces with my kit in case you loose or break something.
