Carli Suspension Ford 2.5" t0 5.5″ Lift Springs for the 2005+ Super Duty Platform. Carli springs are Shot Peened and Pre-Set, then powder coated by the manufacturer ensuring they won’t sag and the finish will last for years to come.
The 2.5″-3.5" Lift Springs are a linear spring with a slightly softer rate than stock to provide a leveled stance and smooth ride through the whole travel stroke.
The 4.5″-5.5" springs are side specific and multi-rate to provide ride comfort and a secondary increased spring rate to prevent the suspension from hitting the bump stops in their massive travel range.
