2014+ 2WD 2500 front suspension

[amauri]

Been working on fine tuning my truck's suspension for towing a 10k-lbs 5th wheel trailer.
I have the rear working very well after adding Timbrens (they sent me a 2nd set of rubbers that did the trick).
Thinking of how to address the issues on the front now, occasional bottoming and bouncing.

FCA shows 25+ different p/n front coils in the parts book, I cross checked many of those numbers and found that in many cases they use the same p/n for both 2WD and 4WD trucks.

Mine is a Crew Cab Big horn 6.7.
I'm thinking that iinstaling a set of front springs off a Mega Cab Laramie 6.7 could do the trick.
My logic is that front springs from a MG that weighs some 300+ lbs more than my CC could give me a little boost in the front end, raise it up just enough to reduce some of the bottoming.

I see a lot of leveling kits available for a 4WD, but none for a 2WD. Not only that, but those kits are designed to lift 2" or more.

Anyone ever experiment with something like what I'm trying to do?
Anyone have some takeoff front coils with stickers showing p/n 68172136AB

Thanks

CST sells a 2wd lift kit that raises the spindle and the springs. Comes with taller spindles and block. You can go 3" to 6" on the kits.

For me running a crew cab St I put in the old springs from my buddies 4*4 mega long bed 2012 and now it sits a little taller and is much stiffer up front. They are also built to handle all the extra weight of the 4*4 parts and such too.

Your truck is a solid front axle so there are no spindles to change, the problem is the crappy stock shocks not the coils and the coils are already very stiff. The reason most leveling kits are taller is they are a little softer spring rate to improve the ride so they need more up travel from ride height to the bump stops but with that said a 4wd kit does work on your truck, the shocks and coils are interchangeable.

I would invest the money in better shocks to start.

Well that would make since. I havent seen the under side of the newer trucks so I didn't know that they had solid axles instead of control arms for the new 2wd trucks.

Thanks for the thoughtful reply.
What you've stated is exactly what I've learned after all my research.

One handy tool I found when researching part numbers, is to go to a dealer's website and find a truck with the trim and options that you want to research, look at the window sticker and get the VIN.
With the last eight numbers of the VIN, you can ask your local dealer to look up part numbers for you and compare to your own truck.
This way, I've been able to determine that the coils and many other parts from a 14+ 2500 2WD are in many cases the same as a 4WD truck.

As far as better shocks, that would certainly make the most sense to start with.
But, after reading countless postings with opinions heavily biased towards the yellow 4600 shocks, I am no more enlightened than before I started on this project.

I'm not convinced that the 4600 or the 5100 shocks will do a whole lot better controlling the bouncing we're experiencing when fully loaded and towing.

The more I read online, the more undecided I become.
Maybe I should just try a set of RS9000XL and experiment with the adj knobs. Don't think I can go wrong since they have a 90 day satisfaction guaranty.

I would go with OEM replacement Fox IFP shocks, they use a lot of rebound dampening and really help control chassis movement https://www.shocksurplus.com/products/fox-2-0-performance-series-shocks-985-24-168 .

The Fox IFP is one of the three on my list within the price range I can afford.

I exchanged a couple emails with one of their tech support reps and liked what he had to say. Pretty much what you said about rebound control, and the fact that for a reasonable fee they can change the damping and/or rebuild them if needed.

Typically the aluminum body ones are not designed to be rebuilt but the steel body are so you may want to clarify that with them.
