    COMP Cams Max-Lift BSR Shaft Rocker Kit Chevy LS7

    No Reviews

    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.
    See 1982-16 for LS3/L92. See 1981-16 for Cathedral Port LS engines.

    COMP Cams GM LS1 Upgraded OEM Rocker Arms – Set of 16

    No Reviews

    Stock LS Rocker arms can experience cageless needle bearing failure when loads are increased. COMP Cams engineers have solved this problem with upgraded Rockers featuring a stronger and more durable trunnion and captured bearing design.

The Rockers feature a black-oxide finish and are available for LS1, LS3 and LS7 valve train geometries. A DIY upgrade kit is also available for users with stock Rockers. It features a magnetic Installation tool, and its cylindrical construction is perfect for use in an arbor press, bench vise or c-clamp.
    With upgraded trunnions that are secured by snap rings along with a black oxide finish, our upgraded OE LS rockers offer higher lift capacity than stock. Featuring a 1.7 ratio, these 1477 rockers fit LS1, LS2 and LS6 engines.
    Available individually under 1477-1.
