Product Description

Ultra Pro Magnum Roller Rocker Arms - (LS1-LS2-LS6 Chevrolet)

As LS1 high horsepower engine combinations continue to grow in popularity, COMP Cams has expanded its line of rocker arms to build components specific to LS1 applications. New Ultra Pro Magnum rockers are made from investment cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings. The design is stronger, stiffer and more durable than the stock OEM parts. They also feature a 1.80:1 ratio (compared to the stock rocker ratio 1.70:1) and utilize a roller tip instead of a slider pad. The higher rocker ratio and increased body stiffness make these rockers a great option for increasing lift without changing cams. This increased stiffness, along with the upgraded trunnion package and roller wheel, also makes them a perfect choice when running aftermarket valve springs.

This LS1 specific roller rocker arm kit is available as a bolt down design that uses a special stud mount rocker and hardened guide plates for customers looking for a fully adjustable valvetrain. This stud mount design is perfect for individuals running mechanical lifters as well. COMP Ultra Pro Magnum rockers arms are available for LS1, LS2 and LS6 inline valve, cathedral port heads and come in individual sets or kits featuring studs and guide plates.

This kit does not include hardened pushrods, but they are available separately. We recommend puchasing an adjustable push rod and using that to determine the proper length for perfect rocker arm geometry and lifter preload.

KIT FEATURES:

  • Increased rocker ratio & stiffness make rockers a great option for increasing lift
  • Investment cast 8650 chromemoly body is stronger, stiffer & more durable than stock 
  • Increased stiffness, upgraded trunnion & roller wheel work with aftermarket valve springs
  • This rocker kit is developed for LS1, LS2, LS6 based automotive and truck applications 
  • Limited Lifetime Warranty - The rocker bodies guaranteed against breakage for life

DETAILS: 1.80:1 ratio and 3/8" to 8mm rocker stud diameter
