If you're dealing with sagging or worn-out RV suspension, these AP Products leaf springs are exactly what you need to get your rig riding properly again. The 2000 pound capacity is suitable for many smaller trailers and campers, providing that crucial support for your axle system. The 2-1/2 inch design with 4 leafs offers the right balance of flexibility and strength - they absorb road bumps without bottoming out. Installation is straightforward if you're mechanically inclined, though having a professional handle it is never a bad idea given the safety implications. I replaced both sides on an older travel trailer that was starting to drag on steep driveways, and the difference was immediate - no more bottoming out on bumps and much more stable towing. The build quality is solid - no rust issues after several months of use through various weather conditions. They're compatible with part number 14-125799, so double-check that matches your existing setup. Whether you're restoring an older RV or just need to refresh worn suspension components, these springs will restore proper ride height and handling. Don't wait until you're damaging your frame or having tire clearance issues - replacing worn leaf springs is one of those maintenance items that dramatically improves both safety and comfort while towing.
