Max-Lift BSR Shaft Rocker Systems for GM LS
Bolt-in, BSR (Bushed
Shaft Rocker)
system increases
valvetrain stiffness
and dynamics,
while reducing deflection. Patent-pending system
ties all eight rocker arms together and fits in the stock rock- er stand. Tri-layer bushings eliminates the high Hertz loading common to needle-bearing trunnions for increased durability. System additionally allows the use of higher lift, more ag- gressive camshaft profiles. Each kit includes (16) rocker arms, (2) rocker shafts, and necessary hardware.
Featuring billet steel rocker trunnions and premium roller bearings, kits deliver improved reliability and stiffness to high-RPM race applications. Choose from upgraded OE rocker arms, or do-it-yourself trunnion only kits.
