S&S Cycle Gear Drive MR103 Camshaft Kit For Harley 1999-2006

S&S Cycle Gear Drive MR103 Camshaft Kit For Harley

Features:

• While it is true that the early version introduced in 1999 was often not well suited to high performance applications, the later version introduced in the 2006 Harley-Davidson Dyna model, and later incorporated in all Big Twins in the 2007 model year, was vastly improved
• The S&S Camshaft Gear Drive Kit increases valve timing accuracy by eliminating timing chain lash and the loosely fit stock cam gears
• This is accomplished by replacing the stock cam drive sprockets and chain with light press fit S&S gears
• Because the chain, chain guides, and tensioner are eliminated, there is no longer a possibility for these parts to fail and damage other parts
• The S&S Camshaft Gear Drive Kit reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes
• As a result, higher cam lifts are possible with the gear drive kit
• Popular camshaft grinds MR103, HP103, 635 H.O. now available for early Twin Cams
• Experience has shown that the new chain drive with hydraulic chain tensioners works well for all but the most demanding high performance applications
• The kit includes gear drive kit, gear cover gasket and cam bearings
