A “Base Kit” SKU must be accompanied by the SKU of a Sway Bar and Leaf Spring option to form a complete system. The Add-a-Packs are made to run with a 4" F350 rear block. If you have an F250, you will need to add the 4" block kit as well.
The Coilover system uses Carli’s Fabricated Coilover Conversion plates as a display for the custom valved KING 2.5″ diameter Remote Reservoir Coilovers. This system's KING Coilovers allows users height adjustability for after-market bumpers and winches while providing an awesome on and off-road ride.
The Carli KING Coilover system rides nearly identical to the Pintop. Take the description for the Carli Backcountry and throw an exponent on it. Benefits of the Carli King Coilover System over the Carli Pintop system are aesthetics (what looks cooler than a coilover?), height adjustability for large bumpers/winch combination and future upgradability. Once the coilover plates are installed, you’re a Coilover tune and Front + Rear Bypass purchase away from owning the Carli King Coilover-Bypass System.
The King Coilover system boasts Carli specific, blueprinted, King 2.5 Coilovers front and piggyback reservoir shocks rear. 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 around the custom pistons based on the only thing that matters to us, 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 can’t 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.
The Coilover is a Jack-of-all-trades system from which every Super Duty owner would benefit. Raising the Super Duty Platform then adding Carli Tuned, 2.5” diameter shocks (55% more piston surface area than a 2.0” shock) will support the argument that these trucks should come equipped with 2.5” shocks from the factory.
The truck will sit 4.5” higher in the front and have more wheel travel thanks to the coilover that mounts in the Carli Coilover Conversion Bracket. 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. Bump Stop Drops protect the shocks from over-compressing, 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.
The rear can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a “light” ¾-ton) or factory leaf-pack modifying Progressive Add-a-Pack (maintains factory payload capacity and pairs with the factory 3-5/8” block). This is where the F250 and F350 are a bit different. Since 2008, the main spring packs on these two trucks is different; the F250 has a lighter rate spring pack than its 350 counterpart. The F250 Add-a-Pack equipped systems are a nice improvement over stock; the F350 with the Add-a-Pack is still very stiff in the rear as the main pack doesn’t move much unless loaded. We recommend the Full Replacement Leaf Spring packs for both trucks but especially the F350 given the super-stiff factory springs. If capacity is a concern, the Full Progressive Leaf Springs can be supplemented back to the factory capacity of a SRW F350 with the addition of our Long-Travel Airbags. The Full Progressive Leaf Spring Pack will shift the axle slightly forward in the wheel well to ensure maximum tire clearance for a 37” M/T at full compression.
If ordering this kit with an Add-a-Pack, Super Duties equipped with a 2″ tall blocks (F250's) from the factory will require either the factory F350 Block or choose the block option we have above (4" ReadyLift Block Kit) to achieve a leveled stance with the Add-a-Pack. Full rear springs do not use a block.
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 Carli 4.5” Ford Systems, we recommend 17”-18” wheels, no more than 9” wide with 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.
