Carli Suspension has brought their 4.5" Pintop system to the 2017+ Ford F250/F350 Super Duty trucks. Utilizing key components to maintain proper suspension geometry and alignment specs, Carli's 4.5" Super Duty suspension systems are the premier option for 2017+ Ford Super Duty pickups. Carli has spent countless time tuning the shocks in this system, offering the best in both on road and off road ride quality and handling.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 Pintop system boasts Carli-specific, blueprinted, King 2.5” shocks on all four corners. In an effort to provide customers 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; they then tuned the shocks around the custom pistons based on the only thing that matters, seat-of-the-pants feel. All of Carli's King shock shafts are 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. Carli plans to release a Torsion Sway Bar in the near future so the end-link options were pulled from the base kit and made selectable in anticipation of the second option. 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, Carli includes Caster Shims to help achieve proper caster.
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 included Carli Fabricated 2” 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 Carli's Long-Travel Airbags (Coming soon for the 2017). 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.
