EBC F-150 USR Slotted Rear Rotors (2021-2026)

Stock rotors work fine until you start pushing harder: spirited canyon runs, towing at highway speeds, or track days where heat, gas, and debris build up faster than factory venting can manage. EBC's USR Slotted Rotors give the rear brakes on your 2021-2026 F-150 a precision-machined solution that handles those conditions without introducing the noise penalty typical of slotted designs.

Narrower multi-slot geometry with progressive machining angles. The slot pattern on a USR rotor is not simply cut straight across the face. EBC machines each slot at a progressive angle, which sweeps gas, water, dirt, and debris clear of the pad surface while maintaining parallel pad wear. That progressive geometry also keeps the rotor running quietly, which separates the USR from louder aftermarket slotted options.

Flat, parallel pad wear over the full service life. Slotted rotors provide their biggest benefit not through raw airflow, but by preventing the ridges that develop on pads and rotors when brake surfaces wear unevenly. Drilled-only designs allow those ridges to form between holes; the USR slot pattern prevents them from forming at all. Consistent pad-to-rotor contact means consistent pedal feel from the first stop to the last.

R90-approved G3000 grey iron blanks, precision machined in the UK or USA. EBC manufactures 92 percent of everything it sells in its own facilities. The USR rotor starts as a high-quality, R90-approved G3000 grey iron blank held to exacting dimensional tolerances. Every incoming batch of bought-in components is verified through metallurgical checks, X-ray inspection, balance testing, and dimensional audits before machining begins.
