Valve Seals / Twin Cam - M8

Features of the Valve Seals

• Includes four seals
• Made in the U.S.A.

Which seal fits your engine

Harley-Davidson changed valve stem diameter at the '05 model year. The seals on this product are the metric stem versions and suit '05-'17 Twin Cam, '04-'22 Sportster XL, the Milwaukee-Eight and the V-Rod.

If your engine is a '99-'04 Twin Cam or an '86-'03 Sportster XL, it runs a 5/16 inch valve stem and takes a different seal. Those are on the Viton Valve Guide Seals product, which also carries the 0.500 inch and 0.530 inch oversized guide options for heads that have been machined.
