Carli Linear-Rate coil springs are built with a custom wind, giving them a smooth linear rate and improved ride over stock. Their design delivers subtle initial compression feel on highway chatter and small bumps as well as smooth compression deeper into the travel. Of course travel is another key point. Unlike most level coils that are about height, these level the truck and increase wheel travel to a massive 9.5" up front.
All 17+ trucks all use the same Carli coil part numbers for the Diesel variant, and the same part number for the gas variant. 17-20 F-250/350 trucks are a 2.5” height increase from factory with a level coil and Tremors are typically 1.5". Normal 20+ Super Duty trucks typically get 3.5” of height increase since Ford actually lowered those trucks from 2020 forward. That said, certain trim packages will sit trucks higher (ie snow plow prep etc) which will influence the lift height relative to stock height.
That said, the final hood and roof height is identical between trucks regardless of the year and trim package since the change in measured lift height is just due to the difference in starting factory coil height. Once those come off and the Carli coils go in, the difference is gone. In short, we like to refer to these as "level height" coils, as referring to specific lift is tricky thanks to how much variance Ford has from the factory depending on trim and options.

Great springs!
Used these gas spec springs on my 97 cclb with 05 axle swap.
Improved the ride over the diesel spec springs.
Ride height is perfect, much smoother than stock thank God lol
Carli Ford Super Duty 2.5"/3.5" Lift Leveling Coil Springs
My favorite truck I have owned was a ford raptor and all because of the suspension. I was really disappointed in the ride and drivability of this 2024 f250. I purchased a competitors leveling kit. It made the truck drive so much worse and the 37/12.50/20s did not help with that. I purchased the carli coils, rear leaf springs and commuter shocks but left the other companies radius drop brackets on. That made a significant difference. I later purchased carli track bar and sway bar. The sway bar did make just as much of a difference as the springs or maybe even more of a difference. I would not say the truck has a ford raptor ride but it is pretty close and for a big heavy diesel pickup it is by far the softest ride I have felt. I also have a fleet of heavy duty pickups( ford, chevy and Ram) that I work on and drive for work so I am very familiar how they all drive. I now really like the way this truck rides and drives. It does ride better than a stock f150. Most people think its crazy to buy a new pickup and change all the suspension but for me I usually just haul a side by side or a jet boat and I wanted the big diesel power, decent fuel mileage and most comfortable ride I could get while not hauling anything. This is it and I will do my next truck the same way.
Ride a lot softer then stock springs. A little more body roll but it’s definitely an up grade from stock springs. Also installed the caster shims.
