Quick Ship SKU #: CS-F45-CO25-08 Carli 4.5" King 2.5 Coilover Suspension System 08-10 Ford 6.4L Powerstroke

This suspension system will be the last system you will buy for your Ford truck. This is not a "lift kit." It is a true suspension system. Carli's Ford Suspension system brings dramatic improvements to the every day street ride, and plenty of dampening for the off road enthusiast.

CARLI TUNED 2.5" KING SHOCKS

At the heart of this Super Duty Coil Over Suspension System lies a KING shock package which delivers impeccable performance and reliability. This system gives 4.5" of lift with 10 inches of wheel travel in the front and 12 inches of wheel travel in the rear. As with all Carli systems, this kit has a vehicle specific valving profile for this suspension system to ensure superior ride quality, handling, and performance. There is a full spring pack option as well as provisions on the included front coilover mounts to add a bypass shock.

The Coilover system boasts Carli specific, blueprinted, King 2.5" Coilovers front and piggyback reservoir shocks rear. In an effort to provide you with the best product, Carli designed a custom piston to determine proper base flow rates to ensure the shock works well in the heavy duty truck platform; the shocks were then tuned around the custom pistons based on the only thing that really matters, seat-of-the-pants feel. Carli rounds off ALL 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.

CARLI COILOVER SUSPENSION SYSTEM COMPONENTS

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

SWAY BAR END LINKS SPECIFICATIONS:

• Corrects sway bar geometry on 4.5" lift
• Direct bolt-in
• Unhindered articulation, 100% rebuildable
• FK bearing 5/8" rod ends

REAR LEAF SPRINGS

The rear can be outfitted with a replacement Full Progressive Spring Pack (reduces capacity to a "light" three-quarter 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. Carli recommends 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 Carli's 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.

ADD-A-PACK SPECIFICATIONS:

• Built in the USA by Deaver Leaf Spring
• Smooth progressive design
• Supplied with u-bolts and hardware
• Provides 2.0" of lift
• OEM load capacity maintained, improved ride
• 3.5" axle tube

FULL PROGRESSIVE LEAF SPRING KIT SPECIFICATIONS:

• Block eliminating
• Light 3/4 ton capacity, full capacity attainable with Long travel airbags
• Includes new u-bolts and rear bump stop drops
• Provides a 1" rear high stance on matching 4.5" suspension systems
• 3.5" axle tube

WHEEL AND TIRE FITMENT

Carli recommends 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.

IMPORTANT NOTES:

• 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.
• ADD-A-PACKS Super-Duties equipped with a factory 2" Block will require the 3-5/8" Factory F350 Block [7C3Z-5598-HB, 7C3Z-5598-JB] to achieve a level stance.
• DRIVELINE: If you have a 2 piece rear drive shaft, you will need to add the Carli Carrier Bearing Drop Kit separately.
