GXD322-38 AR Belly Dump

The Renn Belly Dump is impressive with it’s capacity, strength and trouble free operation. Increased hauling capacity coupled with minimal downtime means increased profits.

We built this unit to be tougher than the day is long with the structural integrity being supplied by our light weight design. Lighter construction means better fuel economy and increased payloads.

The oscillating 5th wheel design coupler system reduces structural stress to your truck and to the unit itself.
