Designed as a bolt-in cam for 88, 95, and 96 CID engines with compression ratios below 9.7:1, it is primarily intended for use with stock, un-ported heads. 3000-5500 rpm. The 510C chain drive camshafts for 1999-’06 use the stock Harley-Davidson® chain drive mechanism and offers an economical option for engines with mild performance upgrades.
Features and Benefits:
- Great way to increase performance at an affordable price
- Quick installation – reuse many stock components
- Can be used with stock valve springs
- Gearcover gasket
- Cam bearings
These cams are not bolt in and will need special valve springs.
Pinion shaft run-out must be checked before installing S&S® gear drive cams.
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 stock crankcase will require clearancing for S&S .625", .640", and .675" lift cams. S&S recommends that gear drive cams be installed by a professional
New cam bearings and a new gearcover gasket are required to complete cam installation. Gear drive cams for 1999-' 06 models require the use of ball bearing style cam
bearing rather than the stock roller bearing. Roller bearings have more internal clearance which can cause excessive gear lash and increased noise. The correct parts are
provided in S&S Camshaft Installation Kit, part #106-5896.
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 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 provide higher seat force should be used.
