We'll do the hard part for you, providing a solid and reliable foundation that you can customize to your heart's content.

Whether you're tackling rocky terrains or navigating through muddy trails, our chassis will provide the strength and stability you need to conquer any obstacle.

The Ultra4 4800 Chasiss below was built out for racer Travis Riley. Travis required a taller roof to accommodate his height, but our standard Rock and Road Chassis is slightly shorter in height, measuring 3-4" less. This ensures a comfortable fit for most off-road enthusiasts while still maintaining the exceptional performance and versatility that our chassis is known for. See his full car specs below.
