Aluminum Underbody-Spring Mount Tarp System for 14 to 23 Foot Dump Bodies keeps your payload in the truck and out of the weather. With strong, reliable technology and fingertip controls, the Underbody-Spring Mount Tarp System has got you covered. The telescoping tarp arms utilize a single underbody-mounted spring instead of two side-mounted springs to maintain tension. The design is simple, strong, and preserves a slim profile where the pivots attach to the dump body. The tarp system works time after time, thanks to its sturdy aluminum arms that telescope to fit dump bodies ranging from 14 ft to 23 ft. An optional aluminum wind deflector protects the tarp from wind and weather bombardment. At the back, an optional extruded aluminum tension bow keeps the tarp from flapping in transit. The system’s gear motor features a bronze alloy gear for long life, protected by a weatherproof enclosure with a chrome cover. The system is available with the following motor options: High speed, 60:1 motor with a 1 or 3 year warranty High torque, 90:1 motor with 3 year warranty Regular speed, 90:1 motor with a 1 or 3 year warranty Tarps are sold separately.
