OPTIONS<br />
Which S&S Gear Drive Cam Kit to Order<br />
• If updating a stock chain drive system, it's easiest to order a complete kit. Includes:<br />
• Camshafts with inner gears<br />
• Outer cam drive gear kit<br />
• Camshaft installation kit<br />
• If replacing cams in an engine already equipped with S&S gear drive cams, order<br />
cams with inner gears and reuse the existing outer gears. Camshaft installation kit for<br />
the appropriate model year is recommended.<br />
• If installing a set of gear drive cams from another manufacturer, order S&S cam gear<br />
kits for the appropriate model year. Each kit provides the inner cam gear as well<br />
as an outer cam gear. Camshaft installation kit for the appropriate model year is<br />
recommended.<br />

NOTES:<br />
• Fuel injection tuning required.<br />
• Pinion shaft run-out must be checked before installing S&S® gear drive cams.<br />
• A hydraulic press and other professional tools are required to install S&S gear drive cams. Additionally, material must be removed from the inner surface of the stock gearcover. The<br />
stock crankcase may require clearancing for S&S .625", .640", and .675" lift cams. S&S recommends that gear drive cams be installed by a professional mechanic.<br />
• Due to the inherent characteristics of gear drives, you may experience more valve train noise with gear driven cams. Oversized and undersized gears are available to help achieve<br />
correct gear lash. We have found that with 160 lb. of valve seat force, the S&S gear drive cams will perform well up to 6200 rpm. If higher rpm is anticipated, valve springs that<br />
provide higher seat force should be used.<br />
• S&S can do a special order cam. Contact your S&S Customer Service Representative for more information.<br />
