Performance 2.5 Development

The Super Duty Suspension line is steadily progressing. The 6-leaf add a pack underwent a revision that brought us much closer to what we can expect from the stock leaf pack and the 4th set of shocks are being dialed in.

Lucky for all of the Super Duty owners, your project starts out at the height of the company's ride quality and performance progression.

Our King 2.5 shock comes with our custom low-flow pistons, designed and developed for straight-axle short/mid travel suspension performance. The signature Carli Suspension ride quality delivers refined manners for daily driving, towing / hauling as well as getting wild in the dirt. One shock tune that does it all.

This story begins with the first Performance 2.5 road tests.


First things first... off come the last shocks, Bilstein 5100s, and it's time to round up all of the hardware for a set of 2.5 Kings with our Total Control Pistons.

The company is founded on it's ride quality and system performance. Product quality isn't just about building something that stands up to the environment, abuse and a few parties... it's about you loving the way your truck drives, everyday, no matter what you're doing or driving on.

A fine balance is under development; one that will dramatically improve your street and in-town driving, highway commutes, towing / hauling and one that will probably scare you in the dirt with its capabilities.

Lucky for the Super Duty crowd, your performance 2.5 system starts out with half a decade of tuning behind it.

An hour or so fitting the shocks to the truck and it was time for the first drive. Just stepping into the truck and taking a local drive is impressive. As far as a first stab at a tune goes and still working with the stock upper leafs, the ride quality is amazing. The expectation of how much comfort can be pulled out of Ford's platform is growing.


The development of the full leaf pack and torsion sway bar will definitely be finishing touches, rounding off some of the rough edges left behind by the factory leafs and sway bar. The first off road tests will be done the first weekend of March and there'll be photos, reviews and details about the development of the Performance 2.5 tune.

So far, the ride quality is impressing us and the best part is, we just got going on this tune.
