f450 suspension systems

The Backcountry on steroids, take the description for the Backcountry and throw an exponent on it. This system is our most popular, all around suspension system. The on road ride is terrific, sharp edges are rounded and light to medium duty offroad escapades become completely controlled and uneventful. Most Carli videos were filmed with the Pintop kit showcasing the extremes of its capability.

Please note that the addition of Carli rear leaf springs will dramatically reduce payload/ towing capacity of a F-450 in favor of better ride quality. If you have heavy towing needs, please call or email so we can get you the right setup!

The Pintop is a Jack-of-all-trades system from which every Super Duty owner would benefit. Raising the Super Duty Platform then adding the 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 higher end systems (currently in development, no ETA) will get you more off-road capability, yes, and even a bit more on-road. The premium paid for these systems; however, doesn’t compare to the on and off-road ride quality per dollar spent on the Pintop. For these reasons, it will likely remain our best seller for years to come.

The Pintop system boasts Carli specific, blueprinted, King 2.5” shocks on all four corners. 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 truck will sit 4.5” higher in the front and have more wheel travel thanks to the taller, Progressive Rate Coil Springs. Radius Arm Drop Brackets reset the pivot point and keep the travel linear for the best ride while the Sway Bar Link & Drop Brackets Kit resets the sway bar engagement point. The End Link Kit is listed as an “option”, but it’s necessary to run. If you desire the ultimate in ride quality, the Torsion sway bar can be added. 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 your factory leaf-pack can be retained if  a custom block (please contact CJC Off Road for details) is utilized. 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.

This system fits Ford F-450 4x4 trucks from 2017, 2018, 2019, 2020, 2021, 2022.

Wheel and Tire: Factory dual rear wheels require spacers when running oversized tires. 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. For more details, see our article on wheel and tire selection and tire pressures:
