Fitment & Compatibility

The listed 2020–2021 Jeep Gladiator JT applications retain the original internal parking brake arrangement. Check the Overland, Rubicon, Sport and listed 2021 trim rows individually rather than applying an open-ended year claim. DS-1393 requires the rear dust shield to be cut for rotor clearance; have that work performed by a competent installer. The included 20-inch braided flexlines must clear moving suspension and wheel parts throughout travel. The original hub is reused. Check the actual wheel shape with the manufacturer diagram; an 18-inch nominal diameter alone is insufficient.

Use the fitment table below to check each listed year, model and brake configuration alongside these installation requirements.
