Chrome Proportioning Valve Kit Designed for Wilwood Master Cylinders, Disc Disc

Chrome Disc/Disc Proportioning Valve Kit for Wilwood Oval Aluminum Tandem Master Cylinders

Finish your Wilwood master cylinder install with a clean, bolt-on proportioning valve setup. This kit was designed specifically to fit Wilwood’s oval-style aluminum tandem master cylinders, and it includes everything you need to mount and plumb the valve in one box.

At the heart of the kit is a chrome disc/disc fixed proportioning valve. It’s a proven GM-style valve, popular on street rods and early muscle cars, that balances front-to-rear brake pressure so your rear discs don’t lock up before your fronts. The valve mounts on the left side with the included chrome bracket, and two stainless steel lines with fittings run from the master cylinder to the valve for a tidy, show-quality look. Stainless mounting hardware is included too.

Need disc/drum instead? We’ll swap in a disc/drum valve at no extra charge. Just leave us a note at checkout.
