This is our newest version for 2017. We've listened to what our customers told us! Comparing ours to the other brands out there- they said that they would like a bigger, thicker retaining clip, so we obliged and incorporated this into our newest run of them. See the pictures and compare the size.
Thicker, Larger retaining clips give a stronger, safer hold to give you a better peace of mind.
MadDogPerformance Rocker Arm Trunion Upgrade Kit for GM LS Engines:
Race Applications Chevy 4.8L 5.3L 5.7L 6.0L 6.2L 7.0L
These LS Series retrofit trunion kits are designed to convert stock LS Series rocker arms into captured roller trunions for high-rpm race applications.
They include the rocker arm trunions, rocker arm bearings, and rocker arm retaining rings for a complete installation.
These are more economical than new race rocker arms, and can handle much higher RPM than the factory ones.
Fits all these applications: LS1/LS2/LS3/LS6/LS7 – 4.8/5.3/5.7/6.0/6.2/7.0 Engines
This kit includes:
16 rocker arm trunnions- LS-type retrofit
32 rocker arm bearings- LS-type retrofit
32 rocker arm Larger retaining rings- LS-type retrofit
16 bolts for LS trunnion kit
2 washers for pressing trunnions
For LS7 engines, the supplied bolts are too long due to the pedestal being built in, so you just reuse your factory rocker bolts. For the rest of the other engines the supplied bolts will work.
