Product Details

The COMP Cams 54-480-11 is a specialized hydraulic roller camshaft engineered for GM LS Gen III/IV engines running remote-mount turbocharger systems. This LSR (LS Race) profile delivers 227/223 degrees of advertised duration, providing an optimal balance of low-end torque and top-end power specifically tuned for forced induction applications.

Key Features:

  • Hydraulic roller design for quieter operation and reduced maintenance compared to solid roller cams
  • 227° intake / 223° exhaust advertised duration optimized for turbo spool and boost response
  • LSR profile specifically designed for remote-mount turbo installations on LS engines
  • Compatible with GM LS Gen III and Gen IV engines including LS1, LS2, LS3, LS6, LQ4, LQ9, and L92
  • Engineered to work with factory hydraulic roller lifters and valve train components
  • Wider lobe separation angle reduces overlap for better boost control and less reversion

This camshaft is ideal for street/strip vehicles and dedicated race applications where a remote turbo setup demands a cam profile that maximizes cylinder filling under boost while maintaining good low-RPM drivability. The hydraulic roller design ensures reliable performance with proper oil pressure and lifter preload adjustment.
