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.

Summit Racing® LS Series Retrofit Trunnion Kits include:

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

I have an lq4 out of a 2005 Chevy 3/4 ton I was wondering if those Trinians would work on that

Asked by MITCHELL A on October 01, 2017


Lq4 is a ls based engine so it will work. I put these in my ls3. Ain't taking a chance of another bearing going out.

Are these the same as the straub or Smith Bros set? Do they have oil grooves like those sets?
