The Super Duty Commuter 2.0 system is designed for people seeking the best on-road ride quality who don’t plan to off-road their vehicle beyond low-speed trail driving. Utilizing Carli SPEC 2.0″ Diameter, Internal Reservoir shocks, we’ve developed a tune that delivers all-around comfort and ride quality designed for on-road, in-town, highway, and towing/hauling.
Shock Valving Option:
This option is to select the valving for your shocks in the kit, depending on which rear leaf spring option you want. This valving matters as the two options are valued differently to compliment the rear leaf springs you wish to use. If you are planning on keeping the stock pack or going with the Carli Add-a-Pack kit, choose the add add-a-pack valving. If you plan on doing the Carli full progressive leaf spring pack, select the full progressive valving.

The mono-tube, internal reservoir, Carli SPEC 2.0 boasts 6063 Aluminum construction, anodized body for corrosion resistance, 5/8″ hardened steel chrome plated shaft, full serviceability & re-buildability, and are built with 1-piece bushings in the 6061 billet rod-ends. These shocks are spec’d with a premium 5WT oil to balance lubricity, consistent damping, and the widest available range in temperature variation.
The truck will sit 2.5” higher in the front and have more wheel travel thanks to the taller, lighter-rate coil springs. Stainless Brake Lines and an Adjustable Track Bar round off the front-end geometry correction while Caster Shims improve on the stock handling.
The rear can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a “light” ¾-ton) or factory leaf-pack modifying Progressive Add-a-Pack (maintains factory payload capacity and pairs with the factory 3-5/8” block). The Full Progressive Leaf Spring Pack offers the best ride and will shift the axle slightly forward in the wheel well to ensure maximum tire clearance for a 37” M/T at full compression. The Full Replacement Leaf Springs do not require any block (factory block is removed). The Add-a-Packs are designed to work with trucks equipped with the 2” rear block. Super Duties equipped with a 3-5/8″ tall block from the factory will require the factory 2″ tall Block to achieve a leveled stance with the Add-a-Pack. Part Number: 7C3Z-5598-L and 7C3Z-5598-K
