Caliper Forged Dynalite 1.38in Pis / 1.25in Rotr

The Wilwood Caliper Forged Dynalite 1.38-inch Piston / 1.25-inch Rotor brake caliper is a purpose-built component for high-performance and heavy-duty braking applications requiring reliable stopping power and thermal management. Engineered with a forged aluminum construction and gray anodized finish, this driver/passenger side caliper delivers the heat dissipation and structural integrity demanded by operators running modified vehicles in duty, tactical transport, or off-road recovery scenarios where brake performance is non-negotiable.

The caliper is sized for a 13.06-inch outer diameter rotor with 1.25-inch thickness, mounted via 5.25-inch lug pattern. The 1.38-inch piston bore generates sufficient clamping force to handle sustained braking loads without fade, while the internal dynalite design reduces unsprung mass—critical for vehicles requiring both stopping authority and responsive handling. Gray anodized finish provides corrosion resistance suitable for extended field deployments in varied climates.

This caliper suits operators upgrading brake systems on trucks, SUVs, or tactical support vehicles where stock components fall short of duty demands. Wilwood's reputation in the performance brake market reflects decades of experience with law enforcement fleet upgrades and specialized vehicle builds. The forged construction and precision machining ensure caliper-to-rotor consistency and long service intervals under duty cycles that would wear inferior components prematurely.

Sold as a single caliper unit (driver or passenger side), this component requires matching counterpart and rotor/pad selection compatible with your vehicle's lug pattern and mounting architecture. Verify OEM or upgrade brake line routing before installation to confirm fit with existing brake system plumbing.
