GNX5 Caliper
GNX5 calipers are the product of Wilwood's in-house FEA design and 3-D modeling technology. With its unyielding strength and superior piston design, the GNX5 generates positive pedal response and high clamping efficiency with a substantial weight savings over comparable OE Calipers. Base model calipers feature a natural aluminum finish protected by a durable clear coat anodizing. Forged billet aluminum bodies, stainless steel pistons, and high-temperature seals put an end to the rust, bore pitting, and seal failures that plague many OE caliper design. GNX5 caliper assemblies are designed use with DOT 3, 4 or 5.1 fluids and should not be used with Dot 5 fluids.  

Stainless steel pistons delay the heat transfer from the pads while the aluminum calipers dissipate the heat quicker than the OE cast iron calipers. Cooler operating temperatures translate into longer service life, regardless of the driving environment. Each caliper also uses stainless SRS bridge plates to reduce wear from pad gouging at the caliper bridge. The spring-loaded action of the SRS plates also reduces noise by eliminating pad rattle and dampening the engagement harmonics   Continue >>
