Reliable stopping power.

My cargo trailer stops much better now. The heat dissipation seems to be a real thing, as I haven't noticed any brake fade on long descents. Solid performance.

Much Better Than Old Brakes

I was using old drum brakes and decided to upgrade. These rotors are a massive improvement. The stopping power is incredible, even with a full load.

Kliment Semrad
Solid upgrade for my 3.5k axle.

The one-piece design is a great idea. It feels much more robust than the old two-piece setup I had. Braking is consistent and smooth.

Perfect Replacement

Needed to replace a rusted rotor and hub. This one-piece design was a perfect fit. The pre-installed races and studs were a nice touch. Saved me a lot of hassle.

Fits a wide range of wheels.

I was worried about wheel compatibility, but my 14" wheels bolted right on without any issues. The studs feel solid and secure.
