CRITICAL: Verify Specifications

Please confirm your firewall mounting configuration, stud threads (10 x 1.25mm), and housing measurements before final purchase. GM G-Series 1-Ton commercial van hydraulic brake assist units require precise identification to guarantee safe operation across all gas, CNG, and diesel engines.

“Engineered to restore original stopping pressure for mid-90s GM full-size 1-ton vans and commercial chassis, ensuring long-term fleet reliability under heavy payloads.”

Restore authentic hydraulic assist performance to your heavy-duty commercial van with the Bexar Pro Hydroboost. This unit is engineered to match the precise operating specifications of the 1994-1996 Chevrolet G30 / G30HD 1 Ton and GMC G3500 models (covering 4.3L V6, 5.7L V8 Gas/CNG, 6.5L Diesel, and 7.4L V8 configurations). Utilizing high-pressure hydraulic fluid supplied directly from your power steering pump, it generates significantly more stopping power than traditional vacuum configurations. Each component is reverse-engineered to bypass original design flaws, ensuring maximum sealing reliability under severe fleet and commercial route conditions.

🛠️ Expert Installation & Field Note

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

Pushrod Alignment: Ensure your firewall pedal pushrod runs completely centered during installation. On G-Series van firewalls, tight engine doghouse clearances often cause off-center installation, leading to fast internal seal scoring and premature leakage.
Hydraulic System Flush: Hydraulic boosters are highly sensitive to abrasive debris trapped inside old fluid lines. We mandate a complete power steering system flush with fresh fluid before connecting this unit to protect the new internal check valves.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process seals the raw iron casing against moisture and road chemicals, preventing external degradation over extended cycles.
