PRW and PQ 2 Stud Rocker Arm System Preparation:
Please read these instructions carefully before beginning your installation. Also, take a moment to review the
limited warranty information. If there are any questions or problems during the installation, please do not hesitate
to contact the PRW Customer Service Hotline at 1-888-377-9779, between the hours of 7 a.m. and 5 p.m. PST
Monday through Friday.
1) Confirm that all parts are included by comparing to the parts list.
2) Make certain that you have all the tools necessary to complete the project.
3) Assembly lube and/or lubricating oil should be readily available for installation.
PRW and PQ 2 Stud Rocker Arm System Installation:
Step 1: After removing the rockers and other components from the package thoroughly wash each piece with
solvent, and then blow dry.
Step 2: Prior to installation, submerge the rockers in engine oil for approximately 30 minutes to insure the roller tip
and fulcrum are properly lubricated.
Step 3: Install the push rods. Make sure the pushrod is properly seated in the lifter. Fill each pushrod with engine
oil, one at a time, as you install each rocker arm. This is to insure immediate lubrication when the engine is started
and help prevent any galling. Also, apply a little moly lube to each push rod tip and all rocker arm push rod seats.
Step 4: Place rocker arms on the rocker arm studs, making sure the flat side of the fulcrum is facing up.
Step 5: Check for clearances. Make sure the rocker does not touch the lower portion of the rocker arm stud, guide
plate, or the stud boss. Also, check the clearance between the spring and the body of the rocker. This should be a
minimum of 0.040”. Normally, the smallest amount of clearance occurs when the valve is closed and the lifter is at
base circle. Always hand turn the crank to verify there is proper clearance of the rocker arm throughout the entire
travel of the valve.
