2010-2021 F250 Auto Spring Rear Add-a-Leaf Kit AS250AAL

Increase Rear Ride Height and Towing Capability for your Super Duty

2010 to 2021 F250s that do some serious towing or hauling are going to need more than a standard rear block in order to get the job done, and Auto Spring is here to help with their high-quality Add-a-Leaf kit for the 2010 to 2021 Super Dutys. This pair of leaf springs install directly into your Super Duty's stock leaf pack without any drilling, cutting or trimming, and add up to 1100lbs of carrying capacity to your truck. The F250 Auto Spring Add-a-Leafs are also capable of increasing rear ride height by up to 1.5" to 2", giving your truck an aggressive look while helping keep your Super Duty level when you're towing or hauling all of your gear. The Auto Spring Add-a-Leaf Kit are perfect compliments to 2" leveling kits or coilovers, giving your Super Duty a mean look while letting you fit on proper-sized off-road tires.

High-Strength Leaf Springs That Reuse the Stock U-Bolts

Each one Auto Spring's F250 Add-a-Leaf Kits comes with a pair of high-quality leaf springs, new pins, and installation instructions. The springs are manufactured out of extremely strong, US-sourced 5160 tempered spring steel that allows them to hold up to just about any application that you have in mind. The springs also have Teflon pads on each end which reduce NVH and help prevent squeaking during break-in. The springs install directly into your Super Duty's factory leaf pack and are completely compatible with your F250's factory U-bolts and rear shocks for most applications. Auto Spring includes a set of four new Grade 5 adapter pins for installation.

Fitment: 2010-2021 F250 Only.

F250 Only: this add-a-leaf kit only fits F250 models. It will not fit F350s. A version for F350s is also available.
