The Wilwood 120-16529 Grand National GN4R is a high-performance forged aluminum four-piston radial mount brake caliper designed for demanding racing and performance applications. Built from high-strength forged billet aluminum, this caliper features a durable hard-anodized finish that provides superior protection against corrosion and wear while dissipating heat effectively.

Key Features:

• Forged aluminum construction for maximum strength and minimal weight
• Four-piston design delivers balanced clamping force and consistent pad wear
• Radial mounting configuration for improved structural rigidity
• Purpose-engineered for 1.25-inch thick rotors with special bracket offset
• Hard-anodized finish resists corrosion and enhances heat dissipation
• GN4R design optimized for Grand National racing applications

This caliper is part of Wilwood's professional-grade Grand National series, offering race-proven performance with precision machined tolerances. The radial mount design provides a stiffer mounting platform compared to traditional axial mounts, reducing flex under heavy braking loads. Compatible with Wilwood's high-performance brake pad compounds for customized friction characteristics to suit your specific application.
