Good Rotor, Minor Cosmetic Flaw

The rotor works perfectly, but there was a small scratch on the surface when it arrived. It didn't affect performance, but I was a little disappointed. Still, it's a solid, heavy-duty part.

Flawless Fit and Function

Replaced my old rotors with these and the difference is night and day. The fit was perfect on my Kodiak setup, and the Dacromet coating looks like it'll hold up to the weather. Brakes feel much more responsive now.

Fits Like a Glove

Needed to replace a single rotor and this one fit my 7K axle perfectly. Bolted right on with no problems. The quality feels premium.

Heavy Duty and Reliable

I haul heavy equipment every week and needed a rotor that could handle the abuse. This one has held up without any issues. No warping, and the stopping power is consistent. Exactly what I was looking for.

Easy Install, Solid Performance

Bolted these right on and bled the lines. The entire process was simple. Performance is great—no brake fade on long descents. The coating is a nice bonus.
