ARK Corporation and AL-KO are two dominant brands for camper/RV and trailer running gear. They're strong in different categories — here's how to choose.
Jockey Wheels: ARK Wins Clearly
The ARK XO350 and XO500 are the benchmark jockey wheels in the market — widely regarded as more robust than AL-KO's equivalent products. Key ARK advantages: higher load ratings for the same product weight, all-metal construction (no plastic structural components), and broader range of clamp sizes.
Verdict on jockey wheels: ARK
Couplings: Context Dependent
AL-KO AKS (highway touring): Market leader for highway towing stability. The integrated friction stabiliser effectively resists yaw-axis sway caused by side winds or truck wash on the highway.
Cruisemaster DO35/DO45 (off-road): The benchmark for serious off-road use. Multi-axis articulation handles corrugated tracks and technical terrain better than the AL-KO AKS.
Verdict: AL-KO for highway, Cruisemaster for off-road
Independent Suspension: AL-KO Dominates
AL-KO's IRS is fitted to the majority of mid-range and premium RVs. It's well-proven, widely serviced, and has excellent parts availability nationally. ARK doesn't manufacture independent suspension systems.
Verdict on suspension: AL-KO
