Disc Brakes, Forged Narrow Superlite 6R Big Brake, Front, Slotted Surface Rotors, Red Calipers, Jeep, Kit

Lifted 4x4s with taller and heavier tire and wheel combinations need Wilwood Forged Narrow Superlite 4R big brake front brake kits to restore stopping power. SL4 kits are specifically engineered per application, but all revolve around Forged Narow Superlite 4R four-piston stainless steel calipers with their 4-symmetrical bores and high clamping force. Oversized, proprietary iron alloy, Spec 37 rotors withstand extreme temperatures and have a high degree of resistance to warping, cracking, distortion, and wear. Both of these parts are built to work hard without issues, but Wilwood's kit doesn't stop there. They also feature forged aluminum mounting hats, BP-10 Smart Pads to increase friction and reduce pad dust, radial mounting brackets, and hardware. Custom wheels and tall tires give character and off-road prowess, but if you can't stop them you're destined to hurt yourself and many others. Wilwood Forged Narrow Superlite 4R big brake front brake kits will help reel in your beast.
