2013+ Ram 2500 Thuren 2.00" coils w/ Fox 2.0 shocks

I can't offer any insight on the coils but I have Timbrens on my truck and I think there's pretty close to an inch or maybe a hair less when you install them without the included spacer. This is on my 2015 2500 which should be the same as your 2014. I can discern no difference in the unloaded or "family loaded" ride (2 adults, 3 kids, 60 lb dog and assorted luggage for a weekend trip).

With about 2600-2800 lbs on the rear axle or maybe a bit more the coils sink enough to contact the Timbren but only lightly with no visible deflection at all. The loaded sag is actually no different or barely different than it was without the Timbrens, but the Timbrens definitely firmed up the ride going down the highway. I mean that in a good way - I think they work great. I don't like airbags especially on a truck like mine that spends time offroad, and I was drawn to the simplicity of the Timbrens.

Definitely post an update of how the setup works if you go forward with it.

Thank you for the info. Yeah, air bags and off road driving don't mix too well which is why I want to stay away from them. The kit is already ordered and it will be a few weeks before I can install. I was already thinking about going ahead and ordering the Timbrens exactly for the reasons you stated even if I don't need them due to sag. In my previous trucks, they really helped make the rig more stable when towing heavy.

I have zero experience with Timbrens but I would think you would need more than a 1" gap off the axle.

BTW...I see bigger tires in your future.

Looking at the Timbren kit instructions for my truck, it states that I should have between a .5" to 1.5" gap unloaded so I am guessing a 1' would be about right. I already have 34.4" Nitto Ridge Grapplers so I doubt I will go any bigger. This truck is already tall enough for what I use it for.

I guess I will just have to install the it and see. I will try to update this thread with pics when I do. Just in case someone has an 8 mile off road trek to get to their hunting cabin or constantly on dirt roads at the farm like me yet still needs to tow 10k+ lbs long distances every now and then.

Not sure I understand your entire question, but we bought a used 05 Ram 2500 with a 2 inch lift on the front end which leveled the truck, but with a ~300 gallon tank in the bed and a 1,000 gallon tank on a custom tandom axle trailer it squats ~2.5 inches which makes the truck look like its dragging its rear. In addition the truck felt very unstable so one afternoon those spacers got yanked out. I'm not sure if this helped the handling or not at this point but it looked nice and level when loaded.

So for me adding 2 inches to the front makes the truck look nice when unloaded, but not so nice when the trucks rear end compresses with a load.

Also the Fox shocks from what I hear require to be rebuilt every 30k-40k miles so you may want to factor that in when purchasing a very $$$ part.

Although I am not to concerned about the cost of it, I will not be using it off road that often to require a re-valved every 30k-40k. Maybe around 50k-60k which is around the time I replace shocks anyways, and a re-valve is usually cheaper than full replacement.

The Thuren coil and track bar kit is little different than a spacer. Spacers generally make the truck ride rougher and do not extend the wheel travel which is counteractive to what I am trying to achieve. The Thuren kit replaces the stock stiff coils up front with softer coils that allow for greater wheel travel to soak up bumps making the vehicle more stable on rough roads. I can't get Bilstiens up front because you have to get shocks specifically valved for the coils which is why I will probably just go with 5100's in the back since I am keeping the rear coils stock.

The rear coils on this truck are pretty strong and hardly budge with added weight compared to leaf spring 3/4 tons I have had before. Empty, the back sits about 3" high. I have had over 2,100 lbs worth of deer corn and feed in the back before and it only lowered the back by about 1.5-1.75" with the front still sitting lower. From my research, the kit will lift the front about 1.25-1.5" over stock once it gets settled which will still leave the back high by about 1.5-1.75".

What I mainly tow never has made my rear squat more than this amount besides the RV which will drop it by a good 2". This is the only thing I am thinking I will need the Timbrens for and set them about an inch off the axle. I prefer not to have air bags at all. I was just wondering if anyone has had this Thuren kit on their Ram 2500 with the rear coil suspension and if they even needed a Timbren kit since the stock rear coils already do a great job of minimizing squat when loaded.

The Blistien 5100 shock is for applications with a lift. Stock ride height should use the 4600.

My 5100'son are for 0-2" lift.

OP, put you some air bags on the rear to compensate for the squat.

Agree with the need to be prepared to install air bags pending your load.... I wanted to mention that as well.

Time for new shocks on my 2014 2500 and decided to just upgrade the front coils as well for a smoother more stable ride when I am driving down the dirt roads at the farm and dear lease(which is often). I will probably just put Bilstien 5100's on the rear with the stock coils.

Does anyone have this setup with a Cummins? If so, how much rake does the truck have afterwards and how much does the rear end squat with a load. I know there will still be a slight rake, but probably not much so I am thinking I might need to add some Timbrens in the rear to compensate for when I tow heavy.
