Special Features

  • LS7 Rocker Arms with Upgraded Bronze Bushing Trunnion Kit Installed Includes: 8 LS7 Intake Rocker Arms, 8 LS7 Exhaust Rocker Arms and 16 Rocker Arm Bolts
  • Bronze Bushing trunnion kit already professionally installed, ready to be bolted on your LS7 heads. Will NOT fit any engines other than LS7.
  • Whether you have a stock or highly modified LS7 engine, replacing your rockers with a upgraded trunnion setup is highly recommended. The stock bearings have a tenancy to fail, sending loose needle bearings through the engine. These rocker arms are a must have for any aggressive heads and cam combo. We disassemble new OEM GM LS7 rocker arms and install our bushing style trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium trunnion Kit.
  • The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. This innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage.
  • Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion. These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it long service life.
