Engine and cam chest parts for the later Twin Cam Dyna, 2006 through 2017 - the years running the revised cam chest with hydraulic chain tensioners. Note the start year: the Dyna got the new chest in 2006, a year before Touring and Softail.

The '06 Dyna Is The Odd One Out
Harley revised the cam chest for 2007 across most of the range, moving to hydraulic tensioners with a new cam support plate and oil pump. The Dyna got it a year early, for 2006. That single year catches people out constantly: an '06 Dyna takes the later parts even though an '06 Road King or Softail takes the earlier ones.
If your Dyna is '05 or older, you want Dyna Twin Cam '99-'05.
What Is Here
Camchest kits in gear and chain drive, camshafts, cam plates, cam chains, cam tensioners, oil pumps, lifters, pushrods and pushrod tubes, valve springs, head breathers and fastener kits from Feuling. S&S Cycles supplies big bore kits, hot set up performance kits, Dyna engine cases and complete T-series long blocks, with tooling from JIMS and forced induction from Trask.
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.
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.
