The JKS ACOS system is very kewl, but I'm just wondering, for those of you who have the ACOS, how often do you actually adjust them once they're on?

VS paying way less for the right size coil spacers from the start?

Do you really take advantage of the "A" in ACOS??? At >> 5 times the cost in parts and install??

Thanks!

I do not have them BUT. Let's say they were the first mod you did, then you add bumpers... winch.. bigger spare.. then yeah I can see needing it to balance it out. Plus on my burb I'd LOVE to be able to adjust the rear coil springs, if I had to tow and do a long trip. also (same as the burb) you might do your install with 1/2 tank of gas, but then decide you wanted the set up level with a full tank... time to re adjust. Let's say you get new tires... and they JUST RUB time to adjust just a bit more... your springs start to sag/settle... time to crank it up just a bit.

I like the idea, and having that ability to fine tune the suspension apeals to me, so when we get an unlimited that will be a first for us.

I've considered this. I have 1" spacers in the front to compensate for the heavy winch and bumper. That was before the lift. I decided to leave them in when the lift was put on, because I liked the way it looked. However, when I get the rear tire carrier I'm afraid it might sag in the rear.

I thought about getting these adjustable spacers, because then I could adjust them over time as things settle and sag. I've grown acustomed to the look and would like to keep it the way it is.

What is involved with the installation?

Why not run the corect springs for the amount of lift that you want....?
Because it's cheaper and easier to adjust the height with the spacers when you end up doing your build in stages. There are allot of variables, and it's hard to say what size coil you'll need to compensate for the weight until you get the weight on the Jeep. I guess that's an option if you have access to different size coils that you can swap on and off, but it's quite a hassle to order and wait. Not to mention expensive when you add something later that changes things.

Looks like that ACOS thing runs about 300 bucks..... Thats about the cost of 2 sets of front springs.

Just throwing it out there.

I wish I had had a crystal ball to have done so. Damn that would have saved me some mullah! But here's how it playsw out in real time,...

Start with a 4" LA kit. Add a Rockhard rear bumper and 37" tire carrier. Add a big new front bumper and powerplant.

And RH Sports Cage. Sliders. Camping equipment in a Tuffy cargo drawer,...

And under carriage armor,...

This is always a "work in progress", no matter who is doing it.

Should I over shoot the fixed spacers and install them, or just do the ACOS???

I could put in several different spacer heights or spring lengths for the cost of the ACOS, it seems. Play the Devil's Advocate and talk me into it.

Cogent.

I like this train of thought, as it is similar to my right brain way of looking at it...

But, like I said before, talk me into it, especially if YOU have the ACOS in place.

Was it worth it?

JKS ACOS
JK Wrangler, 2007+
Location Range Qty Part # Price
Front 1" - 2.5" Pair PN 22101, 2, 5 $277.00

Rear 2" - 4" Pair PN 25702, 3, 4 $380.00

Spacers can be priced at around $30/pair.

Then you have the install cost. It's not the same as installing spacers.

In the big picture after 100+K miles, it amortizes out to zip, zilch, nada.

But up front costs add up at some point.

If you have the ACOS, is it worth it?

for what ever it is worth, when i had my XJ my good friend had one as well. He had the ACOS. He only adjusted them a couple times over a couple years.

I agree the price comes out to about even over a couple years. Don't forget you can sell or hand down to a friend your used springs. If the cost ended up being even over time that is more of a reason to go with coils. I would rather have had some good quality coils with proper rates and travel over a high tech spacer.

Not saying they aren't nice and a great idea, just can never beat the performance of proper coils with any spacer no matter how nice they are.


just me two cents...

Proper coils, shocks, AND, if you must, spacers...thos ACOS products are quite pricey for what you ultimately get.

Cannot help you there. I'm in the same boat deciding if it's what I want to do. For their price I'm leaning towards not buying them, but I haven't made up my mind.
