Master Your 4-Wheel Disc Conversion with the LEZHEY PV4 Performance Kit Upgrading your classic vehicle to four-wheel disc brakes is one of the best safety moves you can make—but only if the hydraulic pressure is balanced correctly. The LEZHEY PV4 P-Kit is the professional-grade solution designed specifically for Disc/Disc setups. We’ve bundled our high-performance brass valve with custom lines and a sturdy bracket to make your installation fast and flawless.

Everything in One Box: Stop wasting time at the auto parts store. Our P-Kit includes: Premium PV4 Brass Valve: Naturally rust-proof and built for high-pressure durability. Pre-Flared Lines: Two stainless/steel lines specifically sized for 1/2" and 9/16" master cylinder ports. Coated Mounting Bracket: A heavy-duty, vibration-resistant bracket for a secure factory-look finish. Fitment & Specs: This kit is an ideal replacement for OE numbers 172-1361, 172-2187, and 172-2174. It fits a wide range of GM, Ford, and Mopar-based custom builds and restorations. Drive with Confidence Don't let a mismatched braking system compromise your hard work.
