The vehicle was powered by four 265 hp (198 kW) GMC diesel engines positioned in the sides of the hull, each of which drove one wheel on land.
The LARC-LX was used to transport wheeled and tracked vehicles, including beach preparation equipment and general cargo, from ship-to-shore or to inland transfer points.
It was also capable of transporting 40 ft (12 m) shipping containers, which could be landed from the LARC either by crane, straddle carriers, or rollers.
Typically, the LARC-LX was carried as deck cargo on a commercial vessel or heavy lift ship to be transported overseas.
However, a few remain in civilian service performing specialty roles, including two operating out of Montross and Tappahannock in Virginia.
