Collection: Ark Corporation

Built in Australia for the Outback and proven across North American overland trails, ARK XO-series trailer jacks (jockey wheels) are engineered to keep working where standard jacks bend, seize, or snap. Sealed bearings shrug off mud and water crossings, dual off-road wheels roll over soft ground, and load ratings from 770 lb up to 1,650 lb cover everything from a teardrop to a fully loaded off-road caravan. These are the same jacks fitted as OEM equipment on Black Series campers — and they ship fast from our warehouse in Upland, CA.

Which ARK XO jack is right for your trailer?

The XO350 (770 lb static) suits lightweight teardrops and small utility trailers. The XO500 and XO500 Black Edition (≈1,100 lb static) handle most mid-size off-road campers. The XO750 (1,650 lb static) is the heavy-duty original, the number-one choice of overland trailer builders for tandem-axle and fully loaded rigs.
