Master Cylinders
Rear master cylinders for Harley-Davidson® and custom builds. GMA Engineering's Kelsey Hayes and Wagner-style 5/8-bore units are the standard for hardtails and forward controls, and V-Twin Mfg offers billet versions for 1979-up. Rebuild kits, plunger pushrod kits and Mid-USA chrome plungers keep an existing master cylinder in service. Match the bore to your caliper: 5/8 for most single-caliper rear setups.
