Thuren rear coil ride height

JamesgPW · Nov 21, 2021

Has any one found or know of a chart approximating the Thuren rear coil ride heights under various weights?

This is not my photo, I stumbled on it on Google but I believe it came off of Reddit or Instagram. I found it very helpful.

This is his photos of Thuren front coils with OEM and Carli in the rear.

I just got finished installing front and rear Thuren springs. Weight in my bed is around 600-700 pounds (fiberglass canopy, Decked unit and tools). I had 1/2" of sag with that weight on the factory springs. After I put on the Thuren springs, the rear came out to be the exact same height, so no additional sag with that weight. Not sure what would happen with a trailer attached. Even though the Thuren springs might be softer, they start out longer than the factory springs by about one coil..

Did you use 1.5” or 0.5” up front?

I used the .5" up front as I already had .5" sag on the factory springs and was concerned that the Thuren would sag more than they did. I did put a 1" spacer in the rear for a little bit of rake.

I’ll be going with the carli r2 this spring. Increased payload and smoother ride.

Already have the Thuren .5 on the front.

That is the build I’m looking at. I have about +300 lbs of sliders and skids on, +100lbs Dethloff bed rack and +300lbs of recovery gear in the bed. I really want to do the 1.5” up front and stock height Thuren rear coils with a 1” spacer but I am afraid I will be nose up with zero rake. I’d like about 0.5” to 0.75” rake.

With the 1" spacer, I have 1.5" of rake. If I had used the 1.5" front springs I would only have .5 " of rake which would go down quickly when I really load the back end of the truck.

Very helpful thread. I'm trying to get my rear end sag gone. My overland setup woth decked system, leitner, fridge, etc is a bit too much. Beem considering airbags even though I know it compromises articulation

You can use Daystar cradles which disconnects the bottom of the airbag to maintain articulation.
