Leaf spring packs, add-a-leaf kits, shackles, hangers, U-bolts and bushings — Rugged Ridge, Skyjacker Suspension, MaxTrac Suspension and more, fitting Chevrolet, GMC, Ford and Dodge vehicles.

Leaf springs do two jobs at once: they locate the axle and they carry the load. That is why a sagging pack is not merely a ride height problem — as the arch flattens, the axle moves and the pinion angle changes with it. Replacing a tired pack restores geometry as much as height.

An add-a-leaf is the inexpensive way to recover sag or gain a modest lift, at the cost of a stiffer ride, because you are adding rate to a spring that has already lost its arch. A full replacement pack costs more and rides properly. Whichever you fit, replace the U-bolts — they are a stretch-to-yield fastener and are not designed to be torqued twice.

Many listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.

Squatting under a load? Our guide to helper springs and air suspension compares the two, and explains what each does not fix.

Common questions

When do leaf springs need replacing?

When the truck sits low at the rear unloaded, when a leaf is cracked, or when the ride has gone harsh because the leaves have lost their arch. Sag is the common one and it happens gradually.

What are add-a-leaf kits?

An extra leaf added to the existing pack to restore or increase capacity. It is cheaper than a new pack but it stiffens the ride, and it does not fix a cracked or worn-out spring.

What are shackles for?

Shackles connect the spring eye to the frame and allow the spring to lengthen as it flexes. Longer shackles raise ride height slightly, which is a different thing from a lift kit.

Do leaf springs come in pairs?

They are sold both ways, but they should be replaced in pairs on an axle. A new spring beside a sagged one leaves the truck sitting unevenly and loads one side harder.
