FACTORY LEAF SPRINGS
Knowing whether to swap leaf springs starts by understanding what’s on the truck and the shortcomings of the design. The factory springs do one thing well – haul. They’re designed and built to handle the max capacity of the truck every day of the truck’s life and, when loaded with max capacity, they ride decent. Thing is, most of these trucks sell to people that will use the HD truck for its intended purpose, but far less frequently than the design intends.

Leaf springs are archaic in design – they either haul well or ride well. You can land anywhere in this spectrum you’d like but there will be sacrifices at the opposite end as you shift throughout. The factory springs slide the scale all the way to the “haul well” end of the spectrum. Let’s dig into their design…

The factory leaf spring are designed with 2-3 stages of spring rate. Pictured is a Stock F250 Leaf Spring Pack with 2 stages.
