reviews of powerslot rotors for f-250 SD 4x2 2003

Looking to upgrade the brakes on my 2003 f-250 SD 7.3L. We pull a 30 ft airstream with regular elec brakes.

I have been seeing on the fordtruck.com forums the power stop rotors are good. I see them on Rockauto with drilled and slotted for the 2 wheel drive unit and wondered how they are preforming with the hawk LT pads.

Not really intrested in the drilled as most race cars use slotted but for what we do it probable ok

SO any reviews on this product.

POWER STOP AR8181XPR Extreme Performance Drilled and Slotted, on rockauto.

    They won't hold as many BTU's because there is less material. They look cool though! :B


    Can you cite a source for your first statement?

    Your second statement is misleading. With the slotted rotors, there is more surface area than conventional rotors, thus the ability to better dissipate the heat. Same principle as all the fins on the head of an air cooled lawnmower engine.

    With rotors, holding the heat, as you assert in your second statement, is the problem. Dissipating (or getting rid of the heat) is desirable.


    Rotors have to absorb heat before they can dissipate it. When you remove material from a rotor, you reduce its ability to absorb heat during the braking event.

    My E450 would boil the brakes in stop and go traffic.
    I replaced all the rotors with the slotted Power Stop. No more issues.

    I stayed away from the drilled rotors, as I have seen them crack at the holes.

    The stock hardware would gas off and turn to a sponge under hard braking, the new brakes wore down.020 I 20k miles and I always have a trailer upwards of 10k Pounds behind me.

    What's good for the track isn't always the best for the road. When I upgraded the old gmc 2500hd I went with a vented disk and paird pads from Raybestos This new system was night and day over stock.
