Ford 4.5" King Unchained 3.0 System, 2005-2007 Base Kit

Base Kit Includes:

If you’re looking for the best on road ride we offer with a huge boost in off-road capability, grab a Dominator. If you’re after a suspension that will allow more off-road performance than the chassis to which it’s bolted, this is your huckleberry. With the Unchained Suspension System, we recommend a roll cage and axle truss. This system is far more capable off-road than even the Coilover-Bypass System.

The truck will sit 4.5” higher in the front and have more wheel travel thanks to the taller, Progressive Rate Coil Springs that mount into the Fabricated Carli Spring Buckets. Radius Arm Drop Brackets reset the pivot point and keep the travel linear for the best ride while Sway Bar Links or Drop Brackets reset the sway bar engagement point. The included Bump Stop Drops protect the shocks from over-compressing while 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.This system boasts Carli Signature tuned, King 3.0” 2-Tube Front and 4-Tube Rear Piggy-Back Bypass Shocks so large, we needed to fabricate custom mounts to fit them; as the old adage goes, there’s no replacement for displacement. The 3.0” shock has a piston surface area 45% greater than a 2.5” King and 126% larger than a factory 2.0” shock making it far more efficient in all situations. Additionally, as explained above, we’ve added bypass tubes to this pinnacle off-road system. The massive surface area and bypass tubes ensure we can achieve unmatched off-road performance while offering a civil & controlled on-road ride. To fit these shocks, we provide fabricated mounts that lift the upper mounting point and position the shock away from the frame while the standard bump stop extensions were shortened to allow for more up-travel to compliment the additional down-travel from the longer shock. In an effort to provide customers with the best product, we designed a custom piston to determine proper base flow rates to ensure the shock works well in the heavy duty truck platform; we then tuned the shocks based on seat-of-the-pants feel. We round off ALL our King shocks with shafts machined and polished from a solid piece of 17-4 Stainless. Unlike King’s standard shafts, there is no coating to wear off, weather is far less likely to hurt them and if there is a small chip, you can round the edges with emery cloth to ensure the seal housing isn’t damaged as they’re not brittle like the stock, hardened shafts. The shocks are finished with King oil good to -55° F. Note that all King shocks are built with a plated steel body. If subjected to inclement weather for extended periods, we recommend wrapping your shocks in 3M to provide a moisture barrier that’s replaceable.

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 4.5” Bypass equipped Ford Systems, we recommend 17”-18” wheels, no more than 9” wide with 4.5”-5” of backspacing with a 37”, E-Rated Tire. 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.
