3.5 inch Add-a-Leafs Kit, 66-77 Ford Bronco SKU: 1490

Early Bronco Rear Leaf Spring Add-a-Leafs | 3.5-Inch Lift

Boost your Bronco’s rear suspension with our Rear Leaf Spring Add-a-Leafs, engineered to provide approximately 3.5 inches of lift while increasing load-carrying capacity. Designed to work with your stock 5- or 6-leaf spring pack, these short add-a-leafs are an ideal solution for those looking to add lift without swapping out their entire spring pack.

While these add-a-leafs stiffen the ride, they offer improved support for carrying gear, towing, or accommodating larger tires. For those seeking a smoother ride quality, we recommend upgrading to our full 3.5" lift rear spring packs instead.

• Fits 1966–77 Ford Broncos: Designed for use with OEM 5–6 leaf spring packs.

• Provides 3.5" of Lift: Gain ride height and rear suspension support without a full spring replacement.

• Increased Load Capacity: Helps reduce sag when hauling gear or towing.

• Stiffens Ride: Great for utility builds—note that it may ride firmer than full lift springs.

• Cost-Effective Upgrade: Adds height and strength without the expense of full replacement springs.

• Bolt-In Installation: Works with your existing leaf spring pack—professional installation recommended.

Lift your 1966-77 Ford Bronco rear end 3.5 inches and add load support with this bolt-on add-a-leaf rear spring kit - simple, rugged, and ready for the trail.
