Wilwood Superlite 4R Rear Drum-to-Disc Brake Kits 140-17542-R

Upgrading the brakes on older trucks makes them safer with improved stopping power. Wilwood's new Forged Superlite 4R rear drum-to-disc conversion kits for select Chevy and GMC trucks and SUVs are one of the best upgrades for overall braking performance. You'll experience more brake clamping force, thermal capacity, improved pedal feel, and confidence--from daily street performance to heavy-use applications, including towing, hauling, commercial workloads, and off-road.
