Fender Flares 99-06 Silverado/Sierra Set of 4 vs Spec-D Fender Flares

Both are matte black, paintable four-piece flare sets for the GMT800 trucks, so the choice comes down to fitment. The Fender Flares set is the one to buy if you own a Suburban, Yukon or Avalanche, because it names those SUVs explicitly. The Spec-D set is the safer pick for Silverado and Sierra pickups, with a documented part number, fleetside bed-length notes and OE-style fitment. Owners of either report the plastic holds up well, but both need paint for a glossy match and both mount with screws and tape rather than factory clips.

• Choose the Fender Flares set if you drive a 2000-2006 Suburban, Yukon or Avalanche and want a full four-corner set listed for your SUV.
• Choose the Spec-D flares if you own a GMT800 Silverado or Sierra fleetside and want a documented part number with clear bed-length and body-style fitment notes.
