The future of the HD truck suspension world is here. Carli suspension has spent months developing this dynamic valving shock package that responsively and constantly adapts to the terrain for the smoothest ride possible. An on board computer and advanced algorithm constantly adjusts the shocks hundreds of times per second. Carli pre-programed three presets for highway, rock crawling, and high speed off road driving.

The system uses a sensor mounted on top of the engine to determine vehicle pitch/roll as well as sensors tied into the OBD2 to read the truck's speed, brake pedal position, accelerator pedal position, and steering wheel rotation. That info then gets interpreted by an algorithm to allow individual adjustment of each shock.

Damping is variable in any setting, meaning the truck can be supple on small chatter, then detect a large impact, rise or dip, and ramp up instantly. That variable damping dramatically reduces body roll in corners in any setting as well and allows for insane small bump sensitivity without giving up big hit composure.

The truck will sit 4.5” higher in the front with this lift 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/sway bar drop kit is listed as an “option”, but it’s necessary to run, unless you opt for the torsion sway bar which dramatically improves ride, but isn't recommended for trucks with in bed campers or a high center of gravity.

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 correct alignment.

This kit REQUIRES the addition of a rear lift option, unless you want a front high stance. Please note that the addition of Carli rear leaf springs will dramatically reduce payload/ towing capacity with an F-450 in favor of better ride quality. We offer a Carli rear airbag kit which has a 2,000 pound capacity per bag, but that will not retain complete factory capacity on these F-450 trucks. If your trailer tongue weight or camper is over about 3,000 pounds, you'll want to stick with the stock rear leaf springs and select the rear block kit option.

Please note that the exact lift amount of these systems can vary slightly depending on how the truck is optioned from Ford, but the truck will sit level with a Carli rear leaf or 5" block.

This system fits Ford F-450 4x4 trucks from 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024+
