Every job asks more of your truck. The A.R.E. MX HD Series Truck Cap answers with a sleek, low profile on the outside and a rugged aluminum frame on the inside. That frame triples what the roof rack and side toolboxes can hold, supporting up to 500 lbs. on top and 200 lbs. per side box. Whatever you’re hauling, the MX HD keeps up — without adding bulk to your truck.
