This suspension system is designed as the do-it-all suspension system. This is not a "lift kit", it is a true suspension system that will technically allow you to do things you probably should not be doing in a daily driven truck.....but you can!

Please see notes below regarding available options and requirements.

This is the true, Jack of all trades suspension system offering the most wheel travel of any Carli system. The Dominator rides better than any other system on the road while boasting off-road manners to rival the Coilover Bypass. No tubes to adjust or user-tunability in this system; Carli has done the hard work for you.

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 Extended Sway Bar End Links 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, you will receive Caster Shims to tighten the steering.

The rear is outfitted with a Full Progressive Spring Pack requiring no block to achieve proper ride height; thus, travel is extended and wheel hop/axle wrap minimized at the cost of 15% less load capacity than a stock F-250. If capacity is a concern, check out the Carli Long Travel Airbags to restore the payload capacity to that of a SRW F-350.

This system boasts Carli Signature tuned, King 3.0" Remote Reservoir shocks so large, they 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. The massive surface area also ensures you'll get amazing off-road performance combined with the best on-road ride of any Carli system. To fit these shocks, Carli 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 you with the best product, a custom piston was designed to determine proper base flow rates to ensure the shock works well in the heavy duty truck platform; the shocks were then tuned based on seat-of-the-pants feel, which really is the only thing that truly matters. ALL of Carli's King shock offerings are finished off 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.

Aesthetically, there will be one huge shock at each corner. The purpose for which the truck's being built does not need to be a consideration when purchasing the Dominator. On Road, it's the best; Off-Road, it's a monster and cycles more travel than any other system offered. All the aforementioned with only 4 completely rebuildable shocks to maintain and stupidly simple operation with the tuning left to the experts. If it's in the budget, this is the Carli recommendation for everyone.

As with the Coilover Bypass, it's recommended that users purchase a Differential Guard for axle protection, High Mount Steering Stabilizer to keep the steering as controlled as the suspension and Fabricated Radius Arms for strength and Limit Strap mounting. At this level of suspension, a roll cage is also recommended if the system will be used to its full off-road potential.

Wheel and Tire: Carli recommends 17"-18" wheels, no more than 9" wide with 5" of backspacing with with a 37", E-Rated Tire. If running the Carli Fabricated Radius Arms, up to 5.5" of backspacing is possible given the additional tire clearance provided by the arm. 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.

  • WHEELS: Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5" of Backspacing on 4.5" Lift Systems
  • TIRES: 37", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 45F/40R.
  • RECOMMENDED CONFIGURATION: Carli 4.5" Systems are Designed and Tested on Vehicles with 17"-18" Wheels with 37", E-Rated Tires. Stock wheels and tires or running a larger wheel diameter will result in a stiffer ride.
  • FULL LEAF SPRINGS: Full Replacement Leaf Spring Option Requires NO BLOCKS to achieve level stance.
  • REAR DRIVESHAFT Trucks equipped with a 2 piece driveshaft will require a Carli Carrier Bearing Drop (sold separately) to ensure proper driveline angles.
