Notes
  • In spite of the similarities between different S&S billet and cast rocker covers, not all parts are interchangeable. See page 3-78 & 3-79 for correct part numbers. The performance-oriented design of the billet rocker boxes permits valve lifts up to .710" with stock or S&S Super Stock® heads, and up to .810" with S&S Special Application heads. S&S roller rocker arms are recommended for high lift cams. Cast rocker boxes may require some minor clearancing, and it is recommended that they be ordered either polished or unfinished, so that clearancing may be done without disturbing chrome plated surfaces. Cast rocker boxes may require minor clearancing. Cylinder heads must be set up correctly for high-lift cams, and it remains the builder’s responsibility to confirm all clearances.

S&S Cycle Rocker Arms and Covers

Overview

S&S Cycle rocker arms and covers are good quality replacement parts that are useful to anyone refitting his engine. The rocker arms are valve train components that are connected to the push rods to facilitate the opening of either intake or exhaust valves. The rocker covers on the other hand are used to cover the valve train preventing spillage of oil all over the engine compartments. The rocker arms are forged from heat treated steel that makes them strong, durable and long lasting. The motorcycle rocker arms and covers are affordable and this makes using these kits one of the cheapest ways of rebuilding your engine. These components fit easily on your engine requiring very little technical knowledge. They do not require you to strip down the engine to install them.
