S&S CYCLE Cam Kit - Chain - 570 Series 330-0003

If you're running a Twin Cam engine and want repeatable, precise valve timing without the slop of a stock chain, a gear drive kit is a non-negotiable upgrade. S&S Cycle's chain-drive solution eliminates timing chain lash entirely, which means tighter tolerances and the ability to run more aggressive cam profiles. You'll see measurable gains in the 3200-3700 rpm sweet spot where most street and track applications live.

This kit reverses the rear cam's rotation direction, creating additional clearance between cam lobes. That extra breathing room opens the door to higher lift camshafts without risk of valve-to-piston or lobe-to-lifter contact—something you simply can't achieve safely with a loosely fitted stock chain.
