Caliper Mounting Kits w/Bracket SL6R / SL4R

The Caliper Mounting Kits w/Bracket SL6R / SL4R represents a critical brake system component designed for professional and enthusiast builders who demand precision hydraulic braking performance. Built by Wilwood, a trusted name in high-performance brake engineering, this caliper mounting kit serves as the mechanical interface between your brake calipers and suspension geometry. Whether you're building a custom off-road platform, upgrading a competition vehicle, or fabricating a specialized tactical transport, proper caliper mounting is non-negotiable for safety and consistent stopping power under extreme conditions.

This kit features a 3.50-inch radial mount design engineered to accommodate Wilwood's Billet Dynapro calipers with precision tolerances. The bracket is machined from aluminum and finished in black anodized coating, providing both weight savings and corrosion resistance critical in field operations or harsh environments. The radial mount geometry allows for angular brake line routing flexibility, reducing line stress and improving system longevity. At just 0.61 lbs, the compact footprint (4 x 1.25 x 7.5 inches) fits tight packaging constraints without sacrificing structural rigidity or load capacity. Billet construction ensures consistent material density and eliminates casting voids that can lead to premature failure under repeated hard braking cycles.

This mounting kit is ideal for builders, fabricators, and engineers integrating Wilwood Dynapro brake systems into custom platforms where OEM solutions are unavailable or inadequate. Mechanics and technicians will appreciate the standardized 3.50-inch radial mount specification, which pairs directly with Wilwood's complete brake ecosystem—minimizing compatibility headaches and ensuring repeatable installation across multiple platforms. Installation requires basic mechanical aptitude and standard fastening hardware; consult Wilwood's technical documentation for your specific application. Proper mounting ensures maximum braking efficiency, reduced line flex, and extended service life in both street and off-road duty cycles.
