RVs and truck campers spend long periods loaded, then cover big distances over rough roads and mountain passes. That combination slowly takes the arch out of leaf springs. Sagging springs reduce ground clearance, upset handling and braking, and put extra stress on hangers, shackles and tires.
Signs your springs are sagging
- The trailer or truck sits noticeably lower than it used to, or leans to one side.
- Tires rub the fender or wheel well over bumps.
- The suspension bottoms out on dips or driveways.
- On a truck carrying a camper, the headlights aim high and steering feels light.
- Uneven tire wear, or springs that look flat or reversed in arch.
More warning signs are in signs your leaf springs need replacing.
Why springs sag
Steel springs lose arch through repeated heavy loading, overloading beyond their rating, corrosion, and age. Weak or broken leaves inside the pack also let the spring flatten. Worn bushings and shackles can make the ride height look worse than the spring itself.
Repair options
- Replacement springs at the correct rating restore the original ride height. Browse leaf springs and trailer parts.
- Custom-built springs can be made for the actual load the vehicle carries. See custom leaf springs.
- Helper options such as add-a-leafs or air bags on trucks. Compare them in lift springs vs add-a-leaf vs air bags.
No spring upgrade raises the vehicle's or trailer's rated capacity (GVWR). Stay within the manufacturer's ratings.
Always recommended to replace in pairs, but single springs are available too.
