Retrofit Rocker Trun­nion Kit

Chevy High Performance - - Parts Bin -

Add a high-lift camshaft and cor­re­spond­ing valvesprings to an LS en­gine and you’re look­ing for trou­ble—trou­ble with the nee­dle bear­ings in the fac­tory rocker arm trun­nions, that is. Those bear­ings are not de­signed to take the ham­mer­ing big­ger cams and stiffer valvesprings dish out. Sum­mit Rac­ing’s Retrofit Trun­nion Kit has hard­ened steel trun­nions with bronze bush­ings that can han­dle loads many times greater than nee­dle bear­ing trun­nions. The kit in­cludes 16 trun­nions, 32 bronze bush­ings, and 32 re­tainer clips, which fits all LS en­gines. Or­der yours at sum­mi­trac­ or by call­ing 800.230.3030.
