COMP Cams Trunnion Kit LS-Type Rocker Retrofit

COMP Cams is proud to announce another industry first: a bolt-in-ready Bushed Shaft Rocker System for GM LS engines. Thanks to innovative engineering, this patent pending Bushed Shaft Rocker System increases valve train stability and durability while decreasing deflection and providing bolt-in convenience for LS1, LS3 and LS7 cylinder heads. The COMP Cams Bushed Shaft Rocker System improves valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. Thin tri-layer rocker arm bushings reduce rocker arm deflection and eliminate the high Hertz loading that can occur in needle bearing equipped rockers. Reduced rocker deflection increases valve train stiffness, ensuring that your LS is more efficient and durable under high loads. COMP Cams engineers worked to ensure long-term valve train durability by perfecting rocker to valve stem geometry and provisioning for supplementary pressurized oiling via threaded ends on the rocker shafts. Additionally, each rocker shaft is Plasma Nitrided, further increasing the system’s durability even when used with aggressive solid roller valve trains. The COMP Cams Bushed Shaft Rocker System for GM LS delivers high-level valve train stability, precise fitment, truer valve train geometry and increased load-bearing capacity in a package that is ready to bolt in that requires no machine work.
This pair of Max-Lift BSR Shaft Mount Rockers for Raised Rectangle Port LS7 engines is a bolt-in rocker upgrade that requires no machine work to install. Clears factory valve covers while greatly increasing valvetrain rigidity.

The COMP Cams GM LS7/Gen V LT Trunnion Upgrade Kit is designed to upgrade the stock needle bearings with full complement Roller trunnions and will improve the reliability of your LS7 and Gen V LT Rocker arms. A must when upgrading to a high performance Camshaft or higher load valve springs.
Kit includes:

Heavy-duty billet Steel Rocker arm trunnions
High needle count Roller bearings
Retaining rings

Our trunnion upgrade kit converts an OE GM LS7 and GEN V LT rocker into a captured trunnion for higher stability and stiffness. Compatible with stock geometry, our trunnion kit can be performed in 30 minutes with a C-clamp or a bench vise.
For GM LS Trunnion Upgrade Kit, see 13702-KIT. Includes virtually the same components as the LS kit, but includes a set of M8x1.25×35 SHCS bolts to fit the GEN V LT instead of the M8x1.25×45 SHCS bolts in the 13702/TL-KIT. Bearings, Retaining Clips and Trunnions are identical. See 13702TL-KIT for GM LS Trunnion Upgrade Kit with Tool.
