Bexar Pro Hydroboost | 1994-1996 GM Diesel Vans & Express 3500

Heavy-Duty Diesel Grade
SPECIAL ORDER: Extra 3-5 Business Days to Ship

CRITICAL: Heavy-Duty Fitment Verification

Please confirm your housing diameter (3.68 in) and firewall mounting specs prior to installation. Mid-90s GM full-size diesel van platforms (equipped with 6.5L Turbo or Naturally Aspirated Diesel engines) demand exact hydraulic assist sizing to guarantee safe commercial operation and proper pedal travel.

“Built to deliver heavy-duty hydraulic stopping power for mid-90s GM commercial diesel vans, cutaways, and passenger chassis handling demanding payload capacities.”

Restore authentic hydraulic assist performance to your commercial fleet with the Bexar Pro Hydroboost. This unit is engineered to match the precise operating specifications of the 1994-1996 Chevrolet G20, G30, GP3500, 1996 Express 3500, and GMC G2500 / G3500 models powered by 6.5L Diesel 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 route and heavy towing conditions.

🛠️ Expert Installation & Field Note

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

Pushrod Alignment: Ensure your firewall pedal pushrod runs completely centered during installation. On G-Series and Express van firewalls, tight engine doghouse clearances can lead to off-center pushrod binding, resulting in accelerated seal scoring and fluid leaks.
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.
