‘24 F250 Alignment from Factory to determine Carli Radius Arms or Factory

[thatdood]

From what I’ve read the caster from factory can vary quit a bit.

Planning on the 5.5 Carli Backcountry on my 24 F250 Tremor being built in two weeks.

Would love to get away with the factory Radius Arms (I do plan on running stock wheels with 37x12.50) tires.

I can use that money and go ahead and install long travel airbags.

Only concern is if I need the Carli Radius Arms in order to get the idea caster.

Should I look at just spending a couple hundred dollars and get the alignment specs when I get it from factory to determine if it was was on the lighter side of caster or not to help determine if I can stick with factory Radius Arms?

take your truck to an alignment shop (the same one you would use after the lift) and get baseline numbers before you modify anything on the suspension. that way you will know where you are starting.
the carli 5.5 uses radius arm drops, so you may end up pretty close to stock specs.
the carli arms obviously have more adjustability to the caster range.

i personally would do the drops, see what the numbers are at, then go from there.

The 5.5" kit has drop brackets for the radius arms so in theory with no other adjustments it should be basically 0 degrees off from factory caster settings and the included caster shims should get you an increase over that so even if your current setup is a little on the light side, I wouldnt think you'd have too much trouble getting it dialed in.

Where you'd want to consider the radius arms is if you are running wide tires and/or positive offset, but the 2023+ trucks have a LOT more clearance for tires so even then, probably not needed.

I had my stock truck (except for carli leafs, shackle, pinion shim) put on the alignment rack today to get a caster baseline. I was surprised. the truck is sitting at 3.1* driver and 3.6* passenger. i wasn't expecting it to be that high.
my truck did loose 1/2" of rake after the leaf spring install. currently it has 2" rake.
my Carli Backcountry level with the new radius arm drops (stock caster shims) will go on next week. I will put the truck back on the rack and see where it is at.
