E1840P Sloppy Stage 2 Camshaft Lifters Rocker Arms Kit for LS1

This aftermarket E1840P Sloppy Stage 2 LS1 Camshaft Lifters Rocker Arms Kit is designed for compatible GM LS1 engine builds using a 3-bolt, non-AFM/DOD valve-train configuration.

The package includes one E1840P Sloppy Stage 2 hydraulic roller camshaft, 16 hydraulic roller lifters, 16 rocker arms and 16 valve springs for performance projects where the major valve-train components are serviced during the same engine teardown.

The camshaft features .585-inch intake and exhaust valve lift, 228°/230° duration at .050-inch lift, a 112° lobe separation angle and a 108° intake centerline. Verify the engine code, cylinder-head and rocker-arm configuration, pushrod length, valve-spring clearance, piston-to-valve clearance, converter requirements and tuning before installation.
