R&P Knowledge Hub
Square tube trailer jacks use internal gears, bearings, and ACME rods to convert handle rotation into vertical lift. Over time, high-load applications can cause wear to lift nuts, gears, and bearings. Rebuild kits allow restoration of lifting performance without replacing the entire jack. Always confirm jack model and internal tube dimensions before ordering service components.
