Wilwood Disc Brakes has just released a new disc brake upgrade kit (P/N 140-12613) for the 1982-1986 Jeep Wrangler CJ. This kit offers simple bolt-on installation to the OE brake axle hubs and
delivers big brake stopping power and styling for the street, off-road, or show to compliment wheel
and tire upgrades on all types of modified/customized Jeeps.
High strength clamping force and positive stopping power is the trademark of the Wilwood forged narrow Superlite 4 (FNSL4R) series calipers. Four symmetrical bore stainless steel pistons provide fully balanced pad loading, along with the corrosion resistance and thermal retardant qualities of the stainless alloy that will keep your calipers cooler and running trouble free for many more miles down the road. Base model kits include either sealed gloss black or red powder coat calipers. Wilwood’s new Quick-Silver finish series calipers are also available as an option by special order and additional cost.
FNSL4R upgrade kits can be purchased with 12.19” ULHP or SRP rotors to maximize braking
capacity. ULHP rotors are smooth face machined from premium grade carbon iron castings to provide
true and precise running for the street. SRP performance rotors feature Wilwood’s signature
directional drill and slot design with a protective E-coat finish. The drill and slot pattern adds race-tech
styling and the venting qualities that preserve pad performance. The heat resistant E-coat finish
protects the rotors from rust on all areas that are not swept clean by the brake pads.
Friction is provided by BP-10 compound Wilwood “Smart pads”. BP-10 is a unique metallic composite formula that provides quiet engagement and low dusting, but with the added temperature range and
higher friction values of a semi-metallic compound pad. BP-10 runs clean and quiet on the street, with improved stopping power and fade resistance for tough roads, or no road at all.
To complete the installation, precision machined and application specific brackets come along with premium grade hardware and alignment shims for a secure and accurate installation. DOT approved flexline kits, required to adapt Wilwood calipers to your chassis plumbing, are available separately, order part number 220-12763.
All of Wilwood’s performance brake kits are loaded with cutting edge technology built on decades of
domination in world motorsports, and proven reliable through Zero PPM defect supply to OEM’s. This
kit will not only optimize the braking performance, it will deliver mile after mile of reliable performance
and service life on your Jeep, on and off-road.
