Anyone using these on the rear? I searched and didn't find anything.
I would plan on doing some air bags for when I need to pull. 2017 4x, came with bilsteins and I've lowered the psi on the tires to 50 or so. Does ride well, but I think it would be better with softer springs in the rear. Traded a 15 ecodiesel in on this one, it was the best riding anything I've driven. I would even consider running some lifted 1/2 ton coils (with air bags when needed), I just don't really want to lift or lower the truck much. Ideas?

You can definitely soften up the rear with the Thuren coils. I do not really recommend air bags on the 2500s, especially after lowering the rear, due to the limited amount of space that is available for the bag and the mount. You will be much better served by a set of Timbrens when you need extra capacity.

Thanks for the info. Anybody have experience with 1/2" drop spring?

I put them on my 2016 ccsb. They lowered the rear right at 1/2 inch. I live in Bend, and was given the coils by accident.... swapped out for the 1 inch lift coils. The ride quality is greatly improved with thuren parts for sure. I wouldn't however recommend running an f rated tire unless you don't mind running low pressure. I had the nitto ridge grappler 12 ply's that ran like sh**. I also had a vibration in the rear which drove me nuts enough to get rid of the truck..... after 6 trips to my local dealership that couldn't figure out where it was coming from.

Literally the first person I have seen with a negative review on the ridge grapplers. Mine have been excellent for 7000 miles. I’d buy another set for sure.

I think it was the combo of the tires and coils that made it ride bad. Soft active coils with stiff sidewall tires= a vibrating 3/4 ton.

Thuren 1/2" lowering coils?

I'm running Thuren springs and Hellwig big wig bags. The ride is soft but not 'squishy' and I leave 12-14 pounds in the bags with no load and it's like they aren't even there (as far as ride quality goes). It doesn't take much with these bags to level a load. The most I've put in them is 44 psi hauling a Ford 545 skip n drag.

Just wrapping this up. Several months ago I installed Thuren 1" front coils, they do seem somewhat softer than stock and improved ride somewhat. Last weekend I put on the Thuren 1" rear coils, the ride quality difference is stunning. Feedback from the back of the truck is negligible and is on par with my the ecodiesel, which is the best riding vehicle I've driven.

Still looks stock'ish too. I have a set of Timbrens, didn't like the way they ride, will be ordering air bags shortly.

I bought a set of timbrens for my 3500 and I can’t stand the way it rides unloaded. I’ll be doing the same.

Anyone using these still and have any reviews on them?

Anyone have some photos of the before and after installing these springs?

I am leaning towards the drop coils in the rear, with a 1 or 2" in the front on my 2018 mega. That should get to where there is zero rake. Not finding much on the drop coils either. I honestly think most people are looking for that lifted look instead. I'd reverse level all the way, but after measuring the distances for the bump stop, the travel wouldn't be much before you were riding on the bump stop if you took 2-2.75" out of the rear.
