Caliper Forged Dynalite 1.75in x .380in Rtr

The Caliper Forged Dynalite 1.75in x .380in Rtr from WILWOOD is a premium lightweight brake caliper engineered for serious vehicle builders and track-focused enthusiasts who demand precision stopping power without sacrificing weight. This forged aluminum caliper sits at the heart of custom brake system builds, delivering the engineering sophistication needed for high-performance road and competition applications. Whether you're upgrading a street rod, vintage race car, or modern performance platform, the Dynalite series offers the design refinement that separates professional installations from amateur upgrades.

WILWOOD's forged construction process creates a caliper body with superior strength-to-weight ratio compared to cast alternatives, critical for reducing unsprung mass and improving brake response. The 1.75-inch piston diameter and .380-inch rotor thickness specifications are engineered for balanced clamping force across modern and vintage rotor profiles, ensuring consistent pad pressure and fade-free performance under sustained braking loads. This rear-position configuration (Rtr designation) integrates seamlessly into proportioning-balanced brake systems, allowing proper weight transfer management between front and rear axles without requiring complex load-sensing compensation valves.

Mechanics and fabricators building custom brake systems—particularly on classic hot rods, custom trucks, and dedicated track cars—choose Dynalite calipers for their straightforward mounting interfaces and compatibility with both manual and power brake systems. The compact 4 x 4 x 8.88-inch footprint allows installation in tight wheel wells where space constraints eliminate heavier OEM components. Installation pairs naturally with WILWOOD proportioning blocks and master cylinders, creating fully balanced brake systems where stopping performance scales predictably with driver input and vehicle load.
