Stock rotors on a work truck or daily-driven F-150 see plenty of heat cycles, road grime, and uneven pad wear over time. EBC's USR Slotted Rotors intercept that degradation cycle early, keeping pad and rotor surfaces flat and parallel through every stop.
Precision slot geometry does the real work. The Ultimax USR's narrower multi-slot pattern is machined at a progressive angle that sweeps gas, water, dirt, and debris clear of the pad face without the noise penalty common to aggressively slotted designs. The result is a quiet-running sport rotor that delivers genuine braking benefits rather than just looking the part.
Flat, parallel pad wear is the primary advantage. EBC engineers are direct about this: slotted rotors excel because they prevent the ridges that form on drilled-only designs. Ridges create inconsistent contact, uneven pressure, and shortened service life for both the pad and the rotor. The USR slot geometry eliminates that failure mode, keeping braking feel consistent from the first stop to the last mile of pad life.
R90-approved G3000 grey iron construction. Every USR blank meets R90 certification standards, the European homologation benchmark for rotor metallurgy and dimensional accuracy. EBC batch-checks incoming materials for metallurgy, balance, dimensional tolerances, and X-ray inspection before a rotor ever reaches the machine. That process applies to all 92% of components manufactured in EBC's own UK and USA facilities.
Designed for fast street use on the 2009 F-150 4.6L 2WD 6-Lug. These front rotors fit the specific bolt pattern and hub geometry of the 2009 F-150 4.6L two-wheel-drive configuration with a 6-lug wheel. Pairing the USR rotor with a matched EBC high-friction pad set maximizes the performance and longevity gains the slot design delivers.
