The CPP Street Beast Universal HydraStop Assembly is designed for custom applications utilizing a 3 3/8 square bolt mounting pattern and provides the hydraulic assist unit with a black mounting bracket. This assembly is ideal for builders who already have a master cylinder and brake valve configuration and want to upgrade from vacuum assist to steering powered hydraulic braking. Perfect for street rods, muscle cars, and custom chassis builds requiring flexible mounting geometry. HydraStop operates from the power steering system and delivers up to 1800 psi at the wheels for consistent pedal response. The assembly includes the hydraulic assist unit, black bracket, AN6 fittings installed, and mounting hardware. Engineered for universal installations requiring the 3 3/8 square bolt pattern. Each HydraStop unit is manufactured new and supported by a limited lifetime warranty when paired with proper filtration.
