• Rocker arms have .75" long bushings instead of the .50" long bushings found on most other rocker arms
• Feature a modified lubrication system with unrestricted roller oiling
• Must be used with adjustable pushrods to obtain proper valve clearance; sold separately
• For ease of adjustment on 91-03 XL and Buell models, use pushrod tube covers DS-193829

NOTES:

S&S roller rocker arms are recommended for use with cams having more than 0.585" of lift.

Adjustable pushrods must be used with S&S roller rocker arms to obtain proper valve clearance.

New rocker arm shafts are recommended for maximum performance and rocker life.

The use of 1.725:1 ratio rocker arms will increase stress on cams, tappets, and pushrods. For this reason they are recommended for racing only and not for street applications.
