Thuren Help....

[BillyGoat]

Hello,

2017 stock PW with 37” KM3/wheels pending the suspension upgrade. I currently run 35” KO2s.

I am interested in the King 2.5 package. I emailed Thuren (not Don) and my questions only received short answers and not really answered, so I am hoping someone will chime in.

I tow a water tank about 2-3 times a month, roughly 9000 lbs ~15 miles round trip. Truck does not sag much as the trailer seems to be balanced well. Top speed about 35mph, no issues towing with current configuration.

I am thinking to get the 1.5” front springs, but should I get the rear springs or will they be too soft to tow that much weight? I would add a 1” spacer to keep the stock rake if needed. Thoughts on keeping the stock rear springs and adding a spacer? Any other suggestions?

Thanks!

You could keep the stock springs for a bit more support, as Thurens springs are a bit softer than the power wagon ones.


However, I think I would get his rear springs also just to reap the benefits of the entire package. Then, add some bags/cradles to the system for when you occasionally tow.

i dont know who in their right mind mind would waste money on airbags for rarely towing a well balanced trailer 15miles. screw airbags. you could use that money for much more valuable things like locker bypass or thuren rear sway bar or master pull winching gear. get thuren front and rear springs. 1" rear spacer will put you pretty close to stock rake if you still have a spare tire at the rear of the truck. if spare is at the front of the bed or no spare at all you might have a hair over stock rake and may want 3/4" spacer which traxda could easily make. hell i have some 1.5" traxda spacers that i bought but never used. if you have simple welding skills you can have them free and just cut them down to 3/4 or 1 and reweld. i would do it for you but ive ive got a million other projects going on

I just threw that option out there as a fix for a sagging issue he may have if he goes with Thuren springs. Sorry man, I went the bag route and now would never want it any other way. My truck is level with no load and level with a load...best of both worlds in my opinion. Just giving my opinion and first hand info.

I wouldn't worry about the sag in this situation. You are talking a 15 mile round trip at 35 mph a few times a month, on a trailer that you say is well balanced and doesn't cause much sag on the stock suspension. If anything you can get the springs and if it's an issue I would get the Timbrens and bolt them in when you need them and put the stock bumps on rest of the time. From the looks of them, and from what others have said, it's like a 10-15 minute job. But again I can't imagine it's going to be an issue to begin with. Not like you are driving hundreds of miles on the interstate.

You might have better luck just calling them, i did that a couple of times.

Yup, communication is my only frustration with Thuren, (they don`t take ph calls) best to text a request to speak via ph.
Text them a short list of your inquires and have a check list handy when they call so you can make sure that you cover all of your questions...

Not a power wagon here but I did add the Thuren recommended Air Lift #57289 bags w/Daystar cradles to my 3inf/1inr King 2.5 system. Adjusts the squat when hauling my 800+lb Harley or towing my 24ft pontoon boat!
Like olyelr said, best of both worlds!

That's crazy I've never had any communication issues with Don. He has always answered emails quickly and thoroughly on my end

If you're going to tow, stick with the OE springs. Thuren springs are softer, so it will likely sag to some degree. If you go with Thuren rear coils you may need to use a WDH or bag it. I use a WDH when towing, but I'm nowhere near max tow capacity. Also, with Thuern 1.5 coils in front and OE in rear your front *maybe* slightly higher when sitting at curb weight.

 

[BillyGoat]

Thanks everyone. I pulled the plug and ordered the 2.5 package with the rear coils. If sag becomes an issue, I will add bags or SUMO/Timbren springs.


I was quoted 12 weeks+ for the shocks. Anybody get them earlier recently?

Thoughts on Timbren vs SUMO vs bags? I may also be in the future market to buy a travel trailer. Not sure which would be the best option for now and later.

Thanks again!

I got my Fox 2.0 shocks in a few days and the same time as the springs a few months ago, but also caught them in a time where they had just received an order of them and had them in stock.

Again, my recommendation would be to just install the suspension and try it with the trailer. Some sag, or even a lot of sag, doesn't necessarily indicate an issue and is often just cosmetic.....especially in your situation with pulling a trailer a short distance at low speeds!

I’m still waiting for my 2.5 rears. King is very behind. Almost month 3.

 

[Overlander]

Any problem with shock fade on the 2.0's? Not on the highway but on heavy trail use? The 2.5's don't provide any superiority to the 2.0 other than the ability to better dissipate heat caused by constant cycling of a heavy truck suspension.

I'd definitely be interested in Foam Cell Pro technology if it were available for the Ram. Though I will say that having an adjustable shock such as the Icon CDCV is nice; firm it up for highway stability, open it way up for offroad compliance.

I wouldn't be surprised on the shocks. Mine took about 6 weeks, but I've had them a couple of years now. I probably underestimated the valving b/c I ordered them at level 3 front and back. Truck rides a bit stiff, but still an improvement over OE set up. Assume you also opted for the SS shafts?

Not bagged, so no opinion.

I can't personally answer that question on the Fox 2.0's right now. Living in the midwest we don't have any large and open spaces where you can do sustained high speed driving off-road like you could in the desert.

 

[BillyGoat]

Yes, I was told that SS are pretty much ordered automatically regardless + boots.

For my use, stage 2 was recommended for both front and rear.

I ordered mine back in April and it took about 13 weeks. Well worth the wait though...trust me

Do you frequently wheel your truck where maximum suspension articulation and travel is important? In my opinion you should avoid Timbrens at all cost. They will defeat any gains your new springs net you in terms of articulation and suspension travel.

If you must have something to assist with the weight I'd go Air bags and Daystar bag cradles. I personally ran this setup in my last truck with decent results. Truth be told though even the cradled bags, when deflated, will hinder your new springs some. The end result in terms of ride quality may be the same as your stock PW springs.

 

[BillyGoat]

Unfortunately, I don’t wheel too much that requires much articulation. I pretty much use the truck on deep rutted logging roads and play in the deep snow and mud at times. I live out on farm land and bought the truck for the lockers and winch. I get off road hunting where the lockers have come in handy plenty of times due to the thick clay ground.

Anybody have any luck with the Sumo setup? It looked like they can unscrew if not needed, but not sure how that would impact the bump stops if they were removed....

 

[Halligan]

Was the purpose of getting Thuren's rear springs to gain additional ride height? Or must you use his springs with the 2.5 Kings? I know on a PW the most you'll gain is 1" over stock with Thuren rear springs. If your stock springs did the job carrying your trailer weight is it worth the hassle for 1" of height? Your cancelling out much of the Thuren goodness with the other weight carrying suspension mods you need to add to haul the trailer.

I just hate to see you spend the money for springs and the additional weight carrying suspension mod's only to end up with the same ride quality as your stock springs. You could use that saved money for some other mods on your PW.

FWIW, I run Thuren front springs and my Stock PW rear springs with the Fox 2.0 shocks. I carry a Yakima rack with RTT, roll top Retrax Tonneau cover, bed full of camping stuff and tools, plus a motorcycle on a hitch rack (guessing 325 lbs between bike and rack) and the truck handles it just fine.

If you must add any weight carrying type spring I 100% vote air bags and cradles. That will give you the best unloaded ride of your 3 mentioned options. I had Timbrens on a truck years ago and took them off. They "hit" way too hard. They're good for a loaded down chassis cab work truck with a flat bed hauling work stuff, not a Power Wagon.
