Chevy Silverado 1500 / GMC SierraRequires a 6-inch to 7-inch suspension lift kit and heavy trimming of front bumper brackets.

Toyota Tacoma (2nd, 3rd, 4th Gen)Requires solid front axle swap or long-travel suspension with aggressive fiberglass widebody fenders and 5.29 differential gears.

Ram 1500 (Bighorn / Laramie / Rebel)Requires a 6-inch suspension lift (RAM TRX fits 37s with minor leveling and front bumper spacing).
