The CPP Street Beast HydraStop Kit is designed for 1955-64 Chevy Full Size applications and features a 90 degree clocked hydraulic unit for improved clearance in tight engine bays. This configuration is ideal for big block, LS, and column shift applications where steering columns and valve covers compete for space near the booster. By rotating the hydraulic ports, this system improves hose routing while maintaining clean firewall installation. HydraStop replaces traditional vacuum assist and uses steering system pressure to deliver up to 1800 psi at the wheels for strong and consistent braking performance. This complete Street Beast kit includes a black direct mount aluminum bracket, rubber high pressure hoses with return lines, AN6 fittings installed, 1 1/8 inch bore master cylinder, adjustable valve, mounting hardware, and black accumulator cover. Engineered specifically for modified 1955-64 Chevy Full Size builds requiring additional clearance without sacrificing braking power. All HydraStop assemblies are brand new and backed by a limited lifetime warranty when installed with proper hydraulic filtration.
