Description
Product Overview
The LXJZCP Hydro‑Boost Seal Repair Kit is engineered to eliminate fluid leaks that occur between the hydro‑boost unit and the master cylinder. Constructed from durable, heat‑resistant polymer, the three‑piece seal set offers a precise fit for a broad spectrum of hydro‑boost systems found in Ford, Chevrolet, GMC, Dodge and Ram models. Each seal is pre‑shaped to match OEM specifications, reducing installation time and minimizing the risk of improper seating. The kit weighs just 0.528 ounces and is packaged in a compact 3.78 x 2.13 x 0.28‑inch box, making storage and handling effortless.
Usage
Designed for both professional workshops and home garages, this kit is ideal for anyone needing to restore brake pressure after a leak diagnosis. Simply remove the old seals, clean the mating surfaces, and install the new components using standard hand tools. The universal design means you do not need to order separate kits for each vehicle make; one kit covers most popular models equipped with hydro‑boost technology. Perfect for routine maintenance, brake system overhauls, or emergency repairs after a leak is detected during a safety inspection.
