Product Description

The Wilwood 140-15304-DR is a high-performance front big-brake kit built for vintage trucks, engineered specifically for 1963-1987 Chevy C10 / GMC C15 models using Wilwood Modular Drop Pro Spindles. Its forged Narrow Superlite 6R six-piston calipers in red powder-coat deliver strong clamping force and precise pedal response.

The 14" SRP drilled and slotted rotors ensure excellent heat dissipation and consistent braking performance. The Spec-37 iron rotors with 72-curved vanes maintain optimal airflow and reduce heat build-up. Aluminum big-brake hats reduce unsprung weight while maintaining strength and reliability.

This kit comes with all necessary hardware for installation and provides a visually striking upgrade as well as serious braking capability. Perfect for muscle truck restorations or high-performance street builds, the 140-15304-DR combines style, durability, and superior braking performance.
