Product Overview
Description
The Super Duty Commuter 2.0 system is designed for people seeking the best on-road ride quality that 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.
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 & rebuildability and are built with 1-peice 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. We back these with a 1-year warranty, serviced by Carli. More details on these shocks can be found HERE.
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 one of 3 options:
Best: A replacement Full Progressive Spring Pack (reduces capacity to a “light” ¾-ton). 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). This will be the best ride.
Better: Factory leaf-pack modifying Progressive Add-a-Pack (maintains factory payload capacity and pairs with the factory 3-5/8” block). 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.
Good: The final option is to select “NO rear option” in this scenario, the rear lift will be left up to the customer as no rear spring modification is purchased. With this option, the rear springs are unaltered and customers will be best with the “PAP” valving profile.
AGAIN: Ensure your System includes the properly valved shocks for the rear spring modification purchased as noted in the above system configurator.
Wheel and Tire: Factory Wheels SHOULD NOT be run with oversized tires. They’re known to rub the radius arm, sway bar and most concerning – Brake Lines. Factory tires and factory wheels will work without issue but we DO NOT recommend running oversized tires on factory wheels. On our 2.5” Ford Systems, we recommend 17”-18” wheels, no more than 9” wide with 5.5” of backspacing with Carli Fabricated Radius Arms or 5” Backspace with factory arms; 5” will require a bit more trimming. Tires, 37×12.5” will fit with some trimming; 35” will likely fit without trimming. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter. For more details, see our article on wheel and tire selection and tire pressures:
