They all work about the same, a soacer mou ted on top of the strut. Check out ReadyLift or Autospring. There are others out there. Don’t go over 2.5”. 2-2.25” is probaly best if you don’t change the rear blocks.

appreciate it. I did some looking around today and settled on the bds with a fox upgrade for the rear.

The preload spaced goes in the strut assembly, on top of the coil spring. You can go about an inch on preload befor it gets to stiff. A preload spacer will limit down travel time n the suspension. The leveling spacer mounts on top of the assembled strut. On a 4x4 you are limited to no more than 2.5” with a leveling spacer due to issues with the axle shaft angles, especially if too much down travel, or droop, occurs.

There is a kit on the market that ReadyLift offers. It’s the 3.5 SST system. It combines a small preload spacer with a leveling spacer for a total of 3.5” of lift. I haven’t seen any reviews on it yet.

Halo/F150 Lifts makes a replacement coil over set up that gets 3” from preload alone, but the shock is designed for it. Most go 2.75” to avoid a rough ride.
