About this part
Double Cab Floor Mats, fitment-checked
Rough Country M-21412 is a floor mat set for Double (Extended) Cab GM trucks — Silverado 1500 and Sierra 1500 (2014–2018), Silverado 1500 LD (2019), and the 2500 HD and 3500 HD pairs (2015–2019). It does not fit trucks with a floor-mounted manual 4x4 shifter or vinyl flooring, and aftermarket under-seat storage may call for trimming.
Coverage runs across the Silverado 1500, Silverado 1500 LD, and the 2500 HD and 3500 HD chassis, plus their GMC Sierra counterparts, in Double Cab form only — the fitment list below shows every trim and drive combination. The mats sit on top of the factory carpet and lift back out for cleaning, with a raised perimeter lip that keeps melted snow, road salt, and spilled coffee from soaking into the carpet beneath. Trucks with aftermarket under-seat storage may need a trim to seat properly. A Limited Lifetime Warranty applies.
