COMP Cams Rocker System BSR Shaft Max-Lift Gen V LT1/ LT2/ LT4/ LT5/ L86

These COMP Cams Rocker Arms (1987-16) are connected in pairs, which increases stiffness, minimizing deflection for maximum performance. Tri-layer bushings instead of needle bearins further enhances precision. Overall these systems also decrease rocker pad wear, for longer service life.

Features and Benefits:
- fits gen 5 LT1, LT2, LT4, LT5 and L86 engines
- Max lift .675 inch
- increases valve train stiffness
- Increased durability

The increased valvetrain stiffness makes any given camshaft perform like a slightly larger one, due to increased lobe contact that isn't lost to deflection. These reinforced rocker arms accomodate higher lift, aggressive camshafts. The system ensures parallel rocker pad and valve tip throughout the contact sweep, allowing the rocker to sweep up to .675" of valve life.

Please Note: Does NOT fit GM Gen V L83 (5.3L) cylinder heads

Vehicle Fitment: 1960-1987 C10
