1964-72 A-Body, 1967-69 F-Body, 1968-74 X-Body Street Beast HydraStop booster assembly with black direct mount bracket
The CPP Street Beast HydraStop Assembly is engineered for 1964-72 A Body, 1967-69 F Body, and 1968-74 X Body GM platforms and provides a direct mount hydraulic assist upgrade using a black aluminum bracket. This assembly is ideal for builders who already have a master cylinder and proportioning valve setup but want to eliminate vacuum assist limitations. Popular in muscle car restomod and LS swap applications, HydraStop operates from steering system pressure to generate up to 1800 psi at the wheels for strong and consistent braking performance. The assembly includes the hydraulic assist unit, black direct mount bracket, AN6 fittings installed, and mounting hardware. Designed specifically for classic GM performance platforms seeking improved pedal feel without relying on engine vacuum. All HydraStop assemblies are brand new units backed by a limited lifetime warranty when installed with proper hydraulic filtration.

Customer Questions
I have a wilwood 1 1/8 master cylinder with the spacer inserted. Does any adjustments need to be made for the push rod spacing of these 2 parts? I see no way to adjust the length for the hydrastop.
You will need to make sure the master cylinder depth is where the Hydrastop needs to be, you can measure depth with our MCDG.
