  • Precision cnc-machined billet aluminium bodies eliminate valvetrain flex.
  • 1.7 standard ratio maintains optimized valve event timing and lift.
  • 3/8-inch stud mounting provides stable attachment for high-revving engines.
  • Roller bearing tip and trunnion dramatically lower internal friction and oil heat.
  • Universal fitment across GM LS1, LS2, and LS6 V8 performance applications.
Crafted from billet aluminium, this high-performance roller rocker set provides a durable 1.7 ratio replacement for Cathedral-port GM LS engines. Built for 3/8-inch rocker studs, the low-friction roller design helps reduce valvetrain noise, lowers operating temperatures, and improves valve guide longevity.
