COMP Cams New LS Shaft-Mount Rocker System Promises Better Valve Train & Engine Performance

COMP Cams Max-Lift BSR Shaft Rocker System - SEMA 2018


LAS VEGAS, NV — COMP Cams’ introduced a new bolt-in shaft rocker system for high-horsepower, high-lift LS engine applications at the 2018 SEMA Show that provides significant valve train stiffness and reduced deflection to add power and performance to your LS build.

The COMP Cams Max-Lift BSR Shaft Rocker System will make the same camshaft perform like a larger camshaft or allow for swapping in more aggressive camshaft altogether.

COMP Cams designed the rocker system so that pressurized oiling is optional, which would further enhance durability. The patent-pending design is a first for the LS market, company officials say.

The new rocker system is available for purchase now.

All eight rockers are tied together on a single shaft that is fully assembled with rocker bodies. That assembly fits in the stock rocker stand. Tri-layer bushings, rather than needle bearings, reduce deflection and eliminate the high Hertz loading from needle-bearing trunnions, COMP Cams officials said. This adds rigidity and durability.

The Max-Lift BSR Shaft Rocker System also features a plasma nitride finish which minimizes friction and further improves durability.

The new COMP Cams rocker system is available for the following LS applications:

The system design transfers more of the lobe lift directly to the valve instead of being absorbed by deflection in the cylinder head and in single-bolt rocker mounting designs.
