Jeep Gladiator Brake Kit - Rear - Wilwood - Narrow Superlite 4R SRP 13.50in Rotor w/Lines - Red (’20–’21) is a rear brake upgrade engineered for 2020–2021 Gladiator models. This kit pairs Wilwood’s Narrow Superlite 4R caliper package with a 13.50" SRP rotor and includes braided brake lines for a ready-to-install rear brake solution.

Built for enthusiasts who demand improved control and reliable hardware, this Wilwood rear kit focuses on consistent performance and durable construction without guessing about fitment. The compact Narrow Superlite 4R caliper is designed for reduced mass compared to larger street kits, while the 13.50" SRP rotor provides a known rotor diameter for heat capacity and pad contact area suitable for street and light-duty use. Included lines upgrade pedal feel and reduce expansion compared with standard rubber hose.
