CRITICAL: Verify Specifications

Please confirm your firewall mounting pattern, 2.34-inch housing diameter, and stud thread dimensions (10 x 1.25mm) prior to installation. Late GMT400 C/K trucks and Suburbans require exact hydraulic assist specifications to safely handle severe towing, 6.5L Diesel, and 7.4L Big-Block braking demands.

“Engineered to restore maximum high-pressure hydraulic stopping power for late GMT400 platform trucks and Suburbans, delivering firm, fade-free braking under heavy payloads.”

Restore confident stopping power and eliminate excessive pedal travel with the Bexar Pro Hydroboost. Built specifically for late GMT400 platform vehicles—including 1997-2000 Chevrolet & GMC C1500, C2500, C3500, C3500HD, K1500, K2500, K3500, and Suburban models—this heavy-duty hydraulic power brake booster draws pressure from the power steering pump to deliver high-output assist.

🛠️ Expert Installation & Field Note

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

Pushrod Alignment: Ensure the pedal pushrod aligns straight with the firewall bracket during reassembly. On GMT400 cabs, angular side-loading will score the main internal spool seals, causing fluid bypass and loss of hydraulic boost.
Hydraulic Fluid Flush: Hydroboost assemblies are highly sensitive to thermal breakdown and metallic contamination in power steering fluid. Perform a complete fluid flush before plumbing high-pressure lines to protect internal spool and check valves.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process protects raw iron castings from road salt and underbody moisture to maximize operational life.
