Rear Brake Kit - GNX4 Rear Kit Brake Kit The GNX4 Brake Kit is the result of Wilwood’s in-house FEA design and 3-D modeling technology.
Paired with 12.00" diameter, .95" width rotors, the GNX4 caliper offers a durable, high torque braking solution.
This upgrade is for AM General Military REV HUMVEE vehicles and will require modifications to the vehicle platform for installation.
With its unyielding strength and superior piston design, the GNX4 caliper generates positive pedal response and high clamping efficiency while providing substantial weight savings over original calipers.
The caliper features a natural aluminum finish protected by a durable clear coat anodizing.
Forged billet aluminum bodies, stainless steel pistons, and high-temperature seals eliminate rust, bore pitting, and seal failures that affect many OE caliper designs.
Stainless steel pistons delay heat transfer from the pads while the aluminum calipers dissipate heat quicker than the OE cast iron calipers.
Cooler operating temperatures lead to longer service life, regardless of the driving environment.
Note: rear kits do not come with provision for parking brake.
