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

How is this different from the 465/475?
The 496 is a bigger, later grind — .485 in. lift with a lopey idle and power that keeps building. It's still a bolt-in: S&S designed it for stock or S&S rocker arms and springs.

Chain or gear drive?
This is the gear-drive kit (330-0826) — no chain or tensioner, more accurate timing, but your pinion runout must be in spec. The chain-drive version is the HPT496C, part 330-0825.

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.
