CRITICAL: Verify Specifications

Please confirm your firewall mounting pattern, 2.16-inch housing diameter, and stud thread dimensions (10 x 1.25mm) prior to installation. GMT400 heavy-duty trucks, Suburbans, and C3500HD chassis-cabs require exact hydraulic assist specifications to guarantee safe stopping under heavy towing and commercial loads.

“Engineered to deliver high-pressure hydraulic stopping force for early 90s GM 3/4-ton, 1-ton, and heavy-duty chassis trucks, ensuring fade-free pedal response under severe payloads.”

Restore maximum braking confidence to your heavy-duty rig with the Bexar Pro Hydroboost. Designed specifically for 1992-1993 Chevrolet & GMC C2500, C3500, K2500, K3500, C2500/K2500 Suburbans, and C3500HD commercial chassis (covering 6.2L Diesel, 6.5L Turbo Diesel, and 7.4L V8 gas engines), this hydraulic unit taps directly into your power steering pump pressure to provide massive stopping power. Engineered to resolve factory wear issues, each unit features 100% new internal seals, diaphragms, and precision-tested check valves for long-term fleet dependability.

🛠️ Expert Installation & Field Note

From our shop experience specializing in heavy-duty commercial brakes since 1985:

Pushrod Alignment: Ensure your firewall pedal linkage aligns completely straight during installation. On GMT400 firewalls, angular pushrod binding will score internal hydraulic seals, leading to rapid pressure loss and fluid leaks.
Hydraulic System Flush: Hydroboost systems are extremely sensitive to abrasive sludge and metal wear debris. We mandate a complete power steering fluid flush before connecting this unit to protect the new internal check valves and spool assembly.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process protects raw iron castings from road salt, grime, and underhood moisture, extending total operational service life.
