Subsequent work involved performing a four-door conversion, refinishing the body in gray bedliner material, and installing steel front and rear bumpers as well as a hood scoop, a winch, LED headlights, side steps, and 17â³ KMC alloy wheels. The interior has been fitted with bucket seats trimmed in black leather in addition to four-point harnesses, custom storage boxes, and a Pyle Bluetooth-capable sound system. Power comes from a 6. 5-liter diesel V8 linked with a four-speed automatic transmission and a dual-range transfer case, and additional equipment includes a roll cage, a custom-fabricated underbody guard, and aftermarket suspension components. The High-Mobility Multipurpose Wheeled Vehicle (HMMWV) went into production for military use in 1984, and the later M1123 variant was used primarily by the United States Marine Corps. Modifications include custom-fabricated front and rear bumpers, a partial roof covering, LED headlights, NAOEVO LED auxiliary lights, a ZESUPER winch, a hood scoop, a hood-mounted shovel and pick axe, side steps, and a custom-fabricated HUMMER tailgate logo. The windshields and washer fluid reservoir were replaced, and a locking fuel filler door was fitted. The 17â³ KMC alloy wheels are mounted with 38Ã13. 5â³ Nitto Trail Grappler M/T tires. Braking is handled by inboard-mounted discs.
