Thuren front leveling coils and payload/towing capacity

[anderson0172]

I am thinking of doing the Thuren 2" leveling coils on the front of my 2020 2500. Does this affect the overall payload capacity or towing capacity? I bumper pull between 8-8500k with a wdh now and plan on upgrading to a 5th wheel in the next few years and don't want to lose any capacity. I was also thinking of possibly doing a 1" spacer on the rear coils to keep a little rake to help keep it level with a trailer attached

The fronts should not affect capacity at all.
I had them in my 16 3500 and loved them, towed heavy many times with them as well and zero complaints.

Did you do anything with the rear to keep it from squatting while towing? I'm thinking of 1" spacers or possibly Timbrens

Curious what the ride is like with just the front thuren coils and stock coils in the rear? Let’s say Fox shocks all the way around. Seems weird to me to only do the fronts but seems like you lose payload with the rear coils which seems even more pointless on a HD truck.

Yes, I think I'm going to go with the 2"coils in the front and Fox shocks all the way around. If the rear squats too much while towing then I may add a 1" spacer or Timbrens or Air bags, we'll see.

I did install a +1” block in the back, but mine was a 3500 with leafs...

I had a 2500 coil spring truck but I never messed with the suspension short of bilstien shocks,

Well definitely let us know. Are you diesel or gas?

I just did the 2 thuren with fox all around. Ride is def more controlled, tad softer in front. It sits with a 1 inch rake if you measure it but to the naked eye the front def looks higher. I will be adding a 1 inch rear spacer for sure... esp for towing.

Thanks, I'll definitely add the spacer in the rear

I also have the Thuren front coils coming next week. Only did 1", cuts the rake down to 1 1/2" and I tow regularly. Also added their sway bar and Fox shocks all the way around.

That sounds about perfect. I have the 2500 Hemi and the least amount of lift they offer for it is 2"

Yeah my current numbers center of hub to fender are 24 1/2" F & 27" R. Dropped the trailer on the hitch and it dropped 1 1/2" so this will be level after install, after adjusting the weight distribution hitch it should gain 3/4" to an inch or so in the rear.

Looks great!

On my 2015 Cummins I added Thuren 2" coils which were way softer feeling than stock. When I hooked up my 8000lb travel trailer it squatted very noticeably and it drove me crazy so I added airbags which fixed it. In all honesty with the Thurens on the front and stock rear it felt a little unbalanced.

 

[Razzman]

I hope to install my Thuren suspension this weekend weather permitting. I'll run the fronts and shocks and see how it feels and if unhappy I'll add rear coils and bags as well. Chris at Thuren advised against it though, said it would mess up the ride, suggested Sumo Springs. Not sure how that would deal with the squat but then i'm not familiar with them.

 

[Motoman501]

I almost immediately put the airbags on so it's possible they helped with the unbalanced feeling. I thought about Sumos but the truck has to squat to engage them so if you are leveled the rear will be squatting when they are working.

Just for info I was using the Thuren shocks on the front, not higher end models.

I'm installing the Fox 2.0 IFP all the way around. We'll see what happens once installed.
