Fitment & Compatibility

The table covers Wrangler JL beginning with 2018 entries, later Wrangler applications through selected 2025 trims, and Gladiator entries beginning in 2020. Trim/year ranges differ, including 4xe and special-edition rows; read every applicable option in the table. This kit retains the documented existing hubs and is designed around the stated factory master-cylinder and ABS operation. Check the 18-inch wheel envelope and route the long flexlines for the actual suspension travel. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.
