Wilwood Front Red Superlite 6R Kit, 12.88-Inch Drilled Rotors for 2007–2018 Jeep Wrangler/JK

Red Superlite 6R calipers are paired with drilled-and-slotted vented rotors for the specified Jeep JK front axle. The conversion retains the hub and needs a separately selected hydraulic flexline kit. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.

Fitment & Compatibility

Use the listed 2007–2017 Wrangler or 2018 Wrangler JK application; the 2018 JK entry must not be extended to the newer JL platform. Confirm the original front hub and five-lug pattern, then use the wheel drawing rather than rim diameter alone. Front flexline kit 220-11237 is specified separately; the kit is designed around the qualifying OE master-cylinder output and ABS function.

Listed models: Wrangler; Wrangler JK. Use the fitment table below for the individual years, submodels and equipment conditions.
