Prop 65 warning
The CPP Street Beast Frame Mounted HydraStop Assembly is built for 1955-59 Chevy Truck applications and provides a hydraulic assist solution that mounts to the frame while retaining the factory brake pedal. This configuration is ideal for builders who want to improve braking performance without converting to a firewall mounted swing pedal system. By replacing vacuum assist and operating from the steering system, HydraStop delivers up to 1800 psi at the wheels for consistent and reliable stopping power. The assembly includes the hydraulic assist unit, frame mount bracket, AN6 fittings installed, and mounting hardware. Designed specifically for 1955-59 Chevy and GMC truck frame mounted installations seeking modern hydraulic brake assist while maintaining original pedal geometry. All HydraStop assemblies are brand new units backed by a limited lifetime warranty when paired with a power steering filter.
