S&S Cycle 465G Camshaft Kit — Gear Drive — 2017-Up M8

S&S's torque cam for the Milwaukee-Eight in gear drive. Same 465 grind as the chain kit — power down low where a bagger rides, bolt-in with stock valvetrain — but the gears hold timing more accurately and there's no chain tensioner to wear. Note S&S's warning: gear-driven cams can produce greater valvetrain noise.

FITMENT

Fits 2017-up Harley-Davidson M8 models, excluding VVT models. In our catalog: 2017-up M8 Touring models.

INSTALLATION

Camshaft installation is internal engine work. The kit includes the bearings, gaskets, o-rings, and hardware S&S specifies for the job; follow the S&S instruction sheet included in the box and your Harley-Davidson service manual for timing and torque specs. S&S publishes an official cam chest install video — it is embedded below. Professional installation is recommended; email us if you'd like a referral to one of our install partners.

QUESTIONS RIDERS ASK

What does the 465 do for a stock 107/114?
It's a torque-first grind: a broad increase in torque and horsepower with most of the power down low in the revs. It's the bolt-in choice for a Touring bike that hauls weight and pulls out of corners.

Anything to check before gear drive?
Yes — pinion shaft runout. Gear drive needs a true crank; if your runout is over spec, run the chain-drive 465C (330-0620) instead. Email us if you're not sure.

Can you ship this to California?
No. This is a race-use-only part that does not conform to CARB standards, so we do not ship it to California — see the California Notice above. It is available to the other 49 states.
