†† This cam kit is not for touring models and does not work with compression over 9.9 to 1 Pinion shaft run-out must be checked before installing S&S® gear drive cams Gear Drive cams should only be used in engines with pinion shaft runout of no more than 003" 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 mechanic 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
