Designed for tight spaces in heavy-duty industrial and automotive applications, Wilwood’s Compact Side Mount Master Cylinder combines high performance with space-saving features. Its ultra-short 3.37-inch body provides an additional 2.16 inches of clearance between the mounting boss and fluid outlet, making it ideal for confined engine bays or equipment compartments. The integral side mounting lugs, with a 3.00-inch center-to-center distance, eliminate the need for a traditional mounting flange, further facilitating installation in restricted areas. This master cylinder offers a full 1.12-inch piston stroke, capable of meeting or exceeding the demands of most full-size cylinders, ensuring reliable braking performance under heavy-duty conditions. The top-radius 1/8-inch NPT fluid outlet port reduces the risk of trapped air, promoting consistent brake pedal feel and responsiveness. The enhanced fluid inlet port supports standard reservoirs, which are included in the kit, and features 11/16-20 internal threads for custom reservoir configurations. Constructed from corrosion-resistant black E-coated aluminum, the body maintains a durable finish suitable for demanding environments, extending service life and reducing maintenance needs. Whether used in commercial vehicles, industrial machinery, or custom automotive builds, this master cylinder provides compactness without compromising performance or reliability.
