Wilwood's GNX4 calipers are the product of their in-house FEA design and 3-D modeling technology. With its unyielding strength and superior piston design, the GNX4s generate positive pedal response and high clamping efficiency with substantial weight savings over comparable OE calipers. Base model calipers feature a natural aluminum finish protected by a durable clearcoat 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 designs.

Note: Current GNX4 caliper assemblies are designed solely
