Fitment

This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.

What it does

Rocker arms transfer motion from the cam or pushrod to the valve. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.

Installation & tips

  • Check rocker geometry and adjust valve lash or preload after installation.
  • Pushrods: Rocker changes can change the pushrod length you need.
  • Valve cover gasket: The cover comes off for this job.
  • Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
