Bagger Twin Cam ‘07 & Up

Engine and cam chest parts for the later Twin Cam touring bikes, 2007 through 2016 - the years running the revised cam chest with hydraulic chain tensioners from the factory. Cams, plates, oil pumps and everything else that lives behind the cam cover.

What Changed In '07

Harley revised the cam chest for 2007, moving to hydraulic cam chain tensioners and a new cam support plate and oil pump. It fixed the wear problem that dogged the earlier motors, and it means the two generations do not share cams, plates, tensioners or pumps. A '06 part and an '07 part look similar and are not interchangeable.

The six-speed transmission arrived the same year, and displacement moved from the 88 and 95 of the early years to the 96 and later the 103.

What Is Here

Camchest kits in gear and chain drive, camshafts, cam plates, cam chains, hydraulic and race-series tensioners, oil pumps, lifters, pushrods and pushrod tubes, valve springs, head breathers and fastener kits, mostly Feuling. S&S Cycles supplies big bore kits, hot set up performance kits and complete long blocks, with tooling from JIMS and Trask forced induction alongside.

Why This Collection Is Split By Motor

Bolt-on parts go by platform. Engine parts go by cam chest. Two Harleys can wear the same badge, the same year, and still take different cams, plates, tensioners and oil pumps because the motor inside them changed. That is why the store keeps a separate page for each engine generation instead of listing everything under one platform.

For Touring the late chest runs 2007 through 2016, and the Milwaukee-Eight takes over from 2017. On a Dyna the same generation starts a year earlier, in 2006 - see Dyna Twin Cam '06-'17.

Before You Order

Displacement, cam chest generation and whether the motor has been apart before all decide what you need. The fitment list on each product page carries the manufacturer's exact year and model coverage - read it, and if you are building rather than repairing, work out the whole combination before buying the first piece. Performance claims belong to the manufacturer; what any part is worth depends on the rest of your build.
