Product Details

The Speedmaster PCE261.1257 is a high-performance roller rocker arm set designed for Chevy GM LS1 engines with stud-mounted configurations. These precision-engineered rocker arms feature a 1.7:1 ratio to optimize valve lift and improve engine breathing for increased horsepower and torque.

Key Features:

  • Heat-treated stainless steel body construction for superior strength and corrosion resistance
  • Alloy steel roller tips reduce friction and wear on valve stems
  • 1.7:1 rocker ratio increases valve lift compared to stock rockers
  • Capable of handling valve spring loads up to 600 lbs
  • Stud mount design for direct installation on LS1 cylinder heads
  • Complete set for all 16 valves

These roller rocker arms provide a durable upgrade over stock stamped steel rockers, offering reduced valvetrain friction and improved reliability in high-performance and racing applications. The roller bearing design minimizes wear while the stainless steel construction ensures long-lasting performance even under demanding conditions.
