Carli Commuter 2.5" Leveling System, 2017-2019 F250 & F350 6.7L
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. Utilizing Fox 2.0” 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 Fox 2.0s boast extruded aluminum construction with a clear anodizing for corrosion resistance, are fully rebuildable and are built with hour-glass bushings in the rod-ends. Fox builds these shocks with their legendary red shock oil that flows well down to -55° F. Unlike most of our suspension systems, the Commuter was tuned with 20”, factory wheels on factory Michelin tires given many in the entry level, 2.5” lift market want the most bang for their buck and will continue to run the factory wheels and tires.
The truck will sit 2.5” higher in the front and have more wheel travel thanks to the lighter rate Carli Coil Springs. The Adjustable Track Bar centers the front axle and Stainless Brake Lines firm up braking and ensure there is enough line for the newfound travel. To round off the front end, we include Caster Shims to tighten the steering and a fabricated, High-Clearance Bump Stop Drop to keep the springs clear from the contacting the factory bump stop. The front Sway Bar Geometry will need to be addressed with your choice of a Sway Bar Drop Bracket (more economical, maintains the factory Sway Bar End Links) or our Extended Sway Bar links – a FAR more robust option. The replacement End Links are the only option compatible with a plow bracket.
The Commuter is the beginning of our no-compromise, custom tuned suspensions. The 2.5” lift variation was tuned with the Progressive Add-a-Pack. The Add-a-Pack installs in place of the lower, factory overload spring effectively making the factory leaf spring pack progressive in nature. In the 2017 platform, the factory block is eliminated with the installation of the Add-a-Pack; thus, axle wrap and wheel hop are non-existent. A rear bump stop drop is included to bridge the distance lost by removing the factory block.
Payload capacity is maintained and the rear end becomes a touch softer while being far more planted and predictable. The custom tuning in the rear Fox 2.0” is optimized to control the combination of our Progressive Add-a-Pack combined with the factory main pack; it’s for this reason we advise against upgrading to the Full Progressive Spring Pack (too much rebound valving for a lighter rate spring).
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.
- The Commuter System has been optimized for use with the Torsion Sway Bar; this sway bar upgrade is a HUGE ride quality upgrade. Maintaining the factory sway bar through use of the Sway Bar Drops or Extended Link Kit is only recommended for customers with snow-plows, in-bed campers or who are constantly hauling to the capacity of the truck.
- The Commuter System has been optimized for use with the Progressive Add-a-Packs on an F250. These are NOT recommended for the F350 (or any F250 equipped with the High Capacity Tow or Tremor Package).
