4.33 out of 5 stars 70 Customer Reviews

Summit Racing™ LS Series retrofit trunnion kits are the answer for LS engines with higher lift camshafts and heavier-than-stock valve springs. These trunnion bushing kits are designed to maximize peace of mind by completely eliminating the needle bearings and providing maximum lubrication to the trunnion—while also providing maximum load carrying capabilities many times greater than needle bearings.

Rocker arm trunnion upgrade kits include:

* 16 micro polished hardened steel pivots/trunnions
* 32 high performance C932 bearing bronze bushings
* 32 retainer clips
