Product Description
OEM LS3 Rocker Arms with CHE Bronze Bushing Trunnion Kit Installed
Fits Rectangle Port GM LS Engines | 6.0L, 6.2L, L99 L76 L92 LS9 LSA L96
These OEM LS3 rocker arms are upgraded with a CHE Bronze Bushing Style Trunnion Kit professionally installed, making them a direct bolt-on reliability upgrade for LS3-style rectangle port cylinder heads. This complete set includes OEM LS3 intake and exhaust rocker arms with the CHE bronze bushing trunnion system already installed, along with new LS3-specific rocker arm bolts.
Factory LS rocker arms rely on needle-bearing trunnions that are known to fail under increased RPM, higher spring pressures, and aggressive camshaft profiles. The CHE bushing-style trunnion upgrade eliminates needle bearings entirely, significantly reducing the risk of valvetrain failure and engine damage, making this an excellent choice for both stock and performance LS3-based builds.
