Built in Australia for the Outback and proven across North American overland trails, ARK makes the XO-series trailer jacks (jockey wheels) fitted as OEM equipment on Black Series campers, along with the couplers, steadies and portable power that go with them. Sealed bearings shrug off mud and water crossings, dual off-road wheels roll over soft ground, and XO load ratings run from 770 lb to 1,650 lb static. Everything below ships from our warehouse in Upland, CA.
XO trailer jacks
The XO350 suits lightweight teardrops and small utility trailers. The XO500 and XO500 Black Edition handle most mid-size off-road campers. The XO750 is the heavy-duty original, also offered as the XO750 Black Edition, the longer XO750 XL, and tube-mount versions in silver and black. For crank-free lifting there are the XO350R and XO500R ratchet jacks. Utility and boat trailers are covered by the 10-inch heavy-duty swing-up jack, the 7,000 lb side-wind jack and the 5,000 lb weld-on or U-bolt jack.
