Question Slotted Rotor Question

I'm looking at replacing my rotors and noticed that "Discount Power Parts" say they can cryogenically treat their slotted rotors prior to shipment, anyone know what this means or does? Thanks

Walt

Cryogenic treatment involves chilling metal down very cold; I think they use liquid nitrogen. It chagnes the grain structure of the metal, making it finer and more uniform. Cryo-treated rotors are said to last two to four times longer than non-treated rotors. It's fairly expensive but people who have used it say good things about it. If you use your truck hard and plan to keep it a long time (both of which you likely are since you're here), cryo-treated rotors are probably worth the extra expense.

FYI, slotted rotors MAY tend to wear out your pads slightly faster. On the flipside, I seem to recall pads lasting LONGER with cryo-treated rotors; go figure.

Keep on Trucking,

Thanks, CC

Your right about keeping the truck and FTE, it's a great place to learn and save big bucks for the DIY kinda guy.

Thanks Again

wfmcbride,

You won't catch a non cyro'ed rotor on my truck ever again!! I got the Powerslots cyro'ed ones and the Hawk pads and the performance difference and the lack of warpage is weeeeeel worth it!! Was good enough that we contated Powerslot and became a warehouse with them!

Hey Thanks Mark,

I'll definitely keep you in mind, DPPI has been added to my favorites, all I need now is to keep my wife from buying another horse.

If you want a stable life "marry a horse"

I'd like to ask an additional question within this thread if I could. Does anyone have any experience w/ these slotted and/or drilled rotors in wintertime w/ salt and such? Do the slots get rusty? Do they still perform as well? Thanks for any info you guys can provide.

I had slotted and drilled rotors on another vehicle of mine. It worked well during it's useful life and had no rusting issues. The only issue I did have with them was that the slotted rotors gave a kind of "fluttering" due to the slots. My wife didn't care too much for it, and when it was time to do the brakes, no-one locally was willing to cut them for me. In the end, I replaced them with the OEM rotors. (keep in mind this was not a SD) But that is my experience with slotted and drilled rotors. As for my truck, I will try the cryo'ed ones next time around.

metalman1320,

I imagine some brands do rust, but the Powerslots use a MIL spec cadium plating and do not, rust in the vent holes is one of the leading causes of rotor warpage too by the way. As far as the slots rusting nope won't happen unless you let them sit for months at a time with no use. Anyone that has a standard brake lathe can turn slotted rotors, the only difference is they must do it very slowly, like they should do regular rotors anyway just takes more time and they usually want to rush the job!! Concerning the fluttering that PHWLEE mentioned I haven't had or had any cuistoemrs call on that, I have them on my 6.0 and the wifes Navigator and no issues. Whatever you do get the cyro'ed rotors, the extra cost is weeeeel worth it in life span and not having any warpage issues. If you have any questions on them please call us.

I second the cryo'ed rotors. They cost more then OEM but are worth it. After a year of use there's no rust, no warpage, no significant wear and I use them hard. Still saving for the rear rotors.

I won't go back to OEM. Without the paperwork in front of me I can't think of who I purchased the rotors from. I think it was A.R.T. ?

I agree with Mark Craig.

I installed some Powerslot Cryo Rotors and Hawk LTS pads that I got from him last weekend. Very nice product and definately improved the braking perfromance of my truck. Great guy to deal with.
