It depends what rotor size you have. I tryed to find sloted rotors and had a heck of a time. I did locate a slotted rotor for each size. SP Performance has a "diamond cut" slotted rotor for 1" and Powerslot rotors have rotors for 1 1/4". Please note that powerslot refuses to say their rotors will work for our trucks - It is listed under 1/2 ton 2wd suburban. Any question please ask. I have the powerslots on my truck now. the SP rotors can be bought at
www.jcwhitney.com and the Powerslot one can be bought at
