Description
Converting to a hydraulic clutch release means finding a master cylinder that delivers the right balance of fluid volume, pedal feel, and packaging--especially in a cramped classic car engine bay. This Wilwood Girling-style compact master cylinder solves that problem with a 0.750" bore and integral reservoir in a lightweight cast aluminum body that tucks in where space is at a premium.
The 0.750" bore diameter is the standard choice for most external slave cylinder setups, providing enough hydraulic volume to fully actuate the release bearing while maintaining a firm, progressive pedal feel. The integral 1.4-ounce reservoir keeps fluid directly at the cylinder, eliminating the need for remote reservoir mounting, banjo fittings, and additional lines--a major simplification for street-driven builds where clean installation matters as much as function.
Wilwood's Girling-style layout uses a 2.25" on-center mounting pattern that fits most aftermarket pedal assemblies and original firewall mounting locations. The 3/8"-24 threaded outlet port accepts banjo bolts or inverted flare fittings, giving you flexibility in your hydraulic line routing. An improved plastic screw-on filler cap protects the fluid from moisture contamination.
Whether you are building a restomod Mustang, upgrading a classic Camaro, or swapping a TREMEC into a vintage Mopar, this master cylinder delivers proven Wilwood reliability in a compact, easy-to-install package.
