2014 Ram Big Horn - Build out

Here we go again! I was unsuccessful at finding any shop in town that would help with these coilovers. I got some pretty unsavoury responses from some of them stating they will no install those for people for this exact reason. That being, needing to take the front end apart in order to make adjustments.

With that I found this on amazon:

ATPEAM Coil Spring Compressor Tool, Heavy Duty Build, Ultra Rugged Coil Spring Compressor Tool Automotive, Strong and Durable Strut Spring Compressor with Safety Guard 2200lb Capacity 11in Jaw Opening

I’m happy to report that this spring compress WILL work on Fox 2.0’s. I was able to successfully tear down both sides, adjust and re-assemble the front end in about 4 hours.


After scouring the internet looking for a reasonably solution that didn’t involve purchasing a floor mount strut spring compressor. I came across the power of these units.

You’ll not the excessive grease on the threads. This is mandatory according to the web of connected computers.

Lucas for the win!

This is my un-marred passenger side and stock set. The bottom of the collar to the bottom of the threads is 2.75” The plan was to attempt to go up 2” as the first adjustment of .5” resulted in .5” height change.

I quickly realized that gaining 2” is likely not going to be possible. I learned that getting the tool onto the lowest and highest coil is extremely difficult. By not being able to do that nicely. You lose quite a bit of compression as the springs outside the tool expand.

Yes I’m in the bite. Those of you that know about these spring systems and these tools know. These things can be terrifying as a failure could result in serious injury! This tool makes me feel significantly more secure. The bar across the top is seemingly crucial. It’s stops the tool from twisting and binding up (which is what happens with the cheapo rental style)

There we go! My finger is where it was originally. I was able to get 1” of adjustment out of the collar. So I am 3.75” from the bottom of the collar to the bottom of the threads. What I expect is going from 5” to 6” ish (or because of how I had the truck parked 4.5” to 5.5”)

The Result

So to my surprise when I went all the way up to 7.25”!!! So potentially too much; but…the key is you have to drive it around to get things to settle.

So that’s what I shall to. It’s a rash to pull the front end apart a bunch to get this sorted. But in the end it’ll be worth it.

I will need an alignment and am hopeful that the wd40 I’ve been putting on those nuts/plates loosens things off :face_holding_back_tears:

My son asked me right after this photo ‘Dad, why did you decide to make your truck like this?’

i hope that is not the end result…
that is way too much preload on the coilover.

-I probably would recommend 2.5” shocks as the bigger springs would be better rated for the size/weight of your truck.
-There is a mathematical equation with Fox shocks (and typically every other brand out there) for the preload setting. “X” amount of preload gives you “Y” height adjustment.
-There is such thing as too much preload. You don’t want to hit a bump and then have your shocks go into coil bind. And inversely, you don’t want to be maxed out on your UCA ball joint.
-Please take my and others advice on this.

For what it is worth I have Fox 2.5 DSC on my 2020 ram with a ADD steel bumper and a winch and have a very different setting.

Ok, I can’t sit back any longer. The math is 1/4 = 1/2” of lift. The shocks I ordered are 0 - 2” of lift. You following me here. The springs are shipped with 0” of pre-load which would be stock height. You can figure this out with exactly what you talked about, which I know, math. So I went up 1” which is 2” of lift and a preload of 1”. I only got 1.5” of lift because of the bumper causes .5” of sag. This is exactly what my ride height is 6.5 Inches. I still have 5.4” of travel and almost 3 times that in spring length. So far on washboard at 80km/hr in corners it’s working better than the stock set up. Way less under steer.

Now please read through the thread, this is quite possibly not the end product as I am working with West Coast Off Roads to dial it in. So if the shop says yeah that’s 2” of preload and that’s too much, we’re sending you a 650lbs spring. I’m confident that I have 1” of preload which is acceptable for the 2.0’s.

If the shop comes back and says we’re shipping you a heavier spring…then that’s what they think. They build these trucks for a living. It has always been my thought that I need a 600 - 650 lbs spring in front. So I’m not at all surprised at what is going on here. It is exactly what I expected.

Now, as for the 2.5’s that’s a totally different shock both in type, size, length everything. So you cannot gauge pre-load to a different shock. Sorry Josh.

I’ll get the answers to all this on monday I imagine. The great thing is I’ll be able to settle this argument you all are having. I will be able to dial the collar down to 0” of pre-load and measure the threads. This will tell me how many inches of pre-load I had

In the meantime I’m going to go back to this

oh nonono
i was just saying i looked at how much you dialed it up it looked off to me, and the issue i was concerned with is how high the collar sits. that’s all.

Sounds good Wes! Was just sharing my example, but sounds like you are happy with your setup.

I will share a link that better explains preload. Many people often confuse the amount of thread that shows above the top collar ‘preload’ when that is not actually the case.
Basically it goes like this. Take the length of the coil spring as it sits on your truck at ride height, (for example 12”) and compare that to the actual length of the spring (for example 14”). Do simple math and you will find that your coil spring has 2” of preload.
Now I don’t know the specific length of your coil spring but based on markings (1600-300-500) it’s a 16” length coil, 3” inner diameter, 500lb spring rate. Its very odd to me that you have a 2” shock with a spring made for a 2.5” but it might be because you have a full-size truck.
So with all that in mind, do what you will.


The belly button birthday I got to wrap and unwrap a present. Finally got around to doing the raptor liner on the rockers/wheel wells on the passenger side.

If you recall from before in the thread. I’m moving away from Color match as it’s a nightmare with insurance repairs in my neck of the woods. Black is the way to go for me. Makes repair with rust paint possible.

Just over a year after the repair from the rear end. Top right dip you can see rust where they just painted over the cracked paint and scuffing with black primer :call_me_hand: for red seal bodymen :-1:


Degrease, rinse, dry, pin stripe tape

Starting to wrap up the present

Present wrapped. These pre-taped drop sheets are awesome! That made the whole process so much more dialled.

TAPEBEAR Pre-Taped Masking Film, Tape and Drape, Plastic Sheeting Roll, Automotive Painters Masking Tape Film, Plastic Sheeting Cover for Appliance, Car, 22inch X 65feet, 3Rolls https://a.co/d/0gCQW21m

Primer, filler and adhesive promoter this time. Hopefully it doesn’t chip as bad.

Second coat done - 2L of raptor liner is just enough.

Finished product. All while letting my ego get the better of me while these cats take the piss out of me over my pre-load :joy:. Thank god they don’t know about me pre-mature-load….
