J-Craft’s Heavy-Duty ULTRA body is strong and reliable, perfect for any job! Available in square or elliptical body styles, we can build the ULTRA that’s right for you.

From its reliable, flat underside, to its rugged boxed sections & optional interior liners – ULTRA is built to haul it all with confidence. J-Craft utilizes high-strength steels, providing maximum durability without sacrificing weight. No matter what hauling test you put it through, this body is ready to work.

Elliptical dump body packages provide extreme durability with rounded sides that greatly reduce impact force and easy discharge of materials. Our single-panel tailgate comes standard with double-link upper hinges to allow easy dumping into any paver or chip spreader.
