Description
Distinctive Style. Elite Performance. Stand out with SP Performance Diamond Slotted rotors. The diamond dimples increase surface area and help the rotor shed heat without drilling through it, while the slots keep the pad surface clean, vent the gases that cause fade at high temperature and channel water away for better wet weather response. Form and function in one rotor. This set covers the rear axle with two rotors in silver zinc coating. Fits 1998-2006 GMC Sierra 1500, 1999-2006 Chevrolet Silverado 1500, 2000-2002, 2004 GMC Yukon, 2000-2002 Chevrolet Suburban 1500, 2000-2002 Chevrolet Tahoe, 2000-2002 GMC Yukon XL 1500, 2002 Chevrolet Avalanche 1500 and 3 more. SP Performance is a women owned business in Lawrenceburg, Indiana. Our rotors are machined in house on CNC equipment, inspected before they ship, and finished in our ZRC coating in grey, black, silver or red for corrosion resistance and a clean look.
