Backcountry 2.0 System 4.5-Inch Front Lift Suspension Kit

The Carli Suspension Backcountry 2.0 system is engineered to enhance the on- and off-road driving experience for 2011-2016 Ford F250 and F350 4x4 trucks. This kit is ideal for owners who desire superior ride quality and capability for occasional off-road excursions without compromising the truck's intended usability for highway driving and towing. It provides a substantial 4.5-inch lift at the front and 0.0-3.5 inches at the rear, significantly increasing wheel travel to 11.3 inches in the front and 13.8 inches in the rear. The base kit is comprehensive, featuring multi-rate coils (CS-FMRC-05) for progressive spring rates, and Carli SPEC 2.0" remote reservoir shocks (CS-F45SPKG-CS20RR-A). These shocks are constructed from 6063 Aluminum with an anodized body, a 5/8" hardened steel chrome-plated shaft, and are fully serviceable. They utilize a premium 5WT oil for optimal performance across various temperatures. The kit also includes essential components like stainless steel brake lines (CS-FORDBBL-11), radius arm drop brackets (CS-FRAD-05) to maintain proper suspension geometry, bump stop drops (CS-FBDF-05-4.5) to protect the shocks, an adjustable track bar (CS-FPRB-05) for precise axle centering, and 1° caster shims (CS-FCASTERSHIM-4.5) to improve steering stability. Optional upgrades include sway bar drop brackets or a custom torsion sway bar kit for enhanced handling, especially on uneven surfaces and during cornering. For the rear suspension, buyers can choose between a Progressive Add-a-Pack (CS-FPAP-11) which maintains factory payload capacity and provides approximately 2.0 inches of lift, or a Full Progressive Leaf Spring Pack (CS-FFSP-11). The latter, built by Deaver, offers a lighter "3/4-Ton" capacity (max 2,000lbs bed load) and positions the truck with a 1-inch rear-high stance, optimizing clearance for 37-inch tires. It's important to note that the F250 and F350 have different factory spring packs, with the F350 being notably stiffer. For those seeking to maintain F350 payload capacity with the full leaf spring pack, Carli's Long-Travel Airbags can be added. Fitment is specified for 2011-2016 Ford F250/F350 4x4 models. The system is designed to accommodate up to 37"x13.50" tires, with a recommendation for 17"-18" wheels, no more than 9" wide with 5" of backspacing. The manufacturer advises against using factory wheels with oversized tires due to potential rubbing on suspension components and brake lines. If ordering with an Add-a-Pack on a factory-equipped 2" block Super Duty, a factory 3-5/8" block (Part Numbers: 7C3Z-5598-HB, 7C3Z-5598-JB) may be required for a leveled stance.
