Question Lowering a TJ? Am I nutz?

So I got this 02 TJ to replace a couple of other vehicles;

1) my old plow truck that I use to clear out a couple hundred feet of driveway
2) my 1999 S10 that I use for running parts

Oh yeah, and I am trying to rig it up to carry a mobility scooter on a beaver-tail carrier stuck in the class III hitch on the back of the rig. The scooter is for my 82 year old mother who would like to start getting out and about with my wife to go shopping.
Well, the beaver tail is fine, the Jeep carries that weight with no issues.
However, as you are probably aware, with the excess ground clearance, the TJ is still a tad bit tall with its stock 15" wheels and tires.
So i am thinking about cutting a coil out of each of the springs, then putting 215-55-16 tires on it. Yes, I am aware that there will be some speedometer error, but that's not a big deal to me.

The question I have is related to other potential issues.
Like driveline angles / U-joint vibration etc. basically some of the same things you have to deal with when you lift them. The tire size change won't change any of the suspension geometry, but the cutting of coils will..

Has anyone else been down this road?

I can probably use air shocks in the winter when I want to get the jeep back up in the air for the plow. Any negative experiences with them? Air-lift bags?

Thanks guys!

Yes, you're nuts.

But, it has been done. To each his own.

I've seen a lowered jeep. Not for me. If you want a lower vehicle why did you pick a jeep? To each his own, just curious.

The original post pretty well explains "why", but to take it to the next level - I simply have too many vehicles and am trying to make each one of them as multi-purpose as I can so I can reduce the fleet just a bit...

My Avalanche 2500 only gets 10 MPG and is too tall for Mom, plus is needed to tow my 10k# trailer..

PT cruiser for mom, Avalanche for plowing.
I don't think you're gonna like a lowered jeep. 16mpg is all you'll get with a rough ride. Lowering it is like castrating it. You're killing it's one thing it does well.

No, your first post states your getting rid of two vehicles. Both of which being trucks that you can put a motorized scooter in the back off. The s-10 would be easy for your mom to get in and out without having to lower. You could lower your driveway plow truck or lower your avalanche 2500 that is used to haul a 10k trailer. But to take it to the next level, Look dude you came on here asking what we thought and you probably already knew no one would like the idea.

I'd be worried about cutting the springs... Maybe find a donor vehicle with good springs that are a better height? Crown Vic?? Idk just a guess.

You can add 2" without driveline issues. Maybe can also lower 2"?

Sorry I got no answers but just trying to encourage folks to think and be helpful lol.

Had mom try getting in and out yet? She may have issues since the tub has a lip to step over getting in and out, unlike a car or truck that is usually flat floorboard to door. Takes some getting used to and if she already has mobility issues they may just get worse. Lowering the jeep won't make it any easier either, just lower.

I like the idea, if I had mobility issues, I'd want my family to fix the jeep so I could still ride in it.

They sell coils: http://www.streetbeatcustoms.com/H&R...ng-52107/6811/

Then make sure you have side steps.

And get some overhead grab handles: http://www.quadratec.com/products/14018_7X_PG.htm

Just some ideas...

LOL.. Little bit of everything here!

That's cool.. I knew the question would throw a couple of you for a loop..

Just a little history on me (me being a new guy and all).. The wife and I are in our early 60s and live in a small town in rural MN.

The S10 - 2WD, peg-leg, nice little truck and almost like my best buddy.. Problem is that he has a stick in him and I just don't want to convert him to an automatic for the wife to drive., He would be perfect for toting Mom, but... remember, I need to thin the herd..

The Avalanche - Sure I could plow with him, but the truck is worse than the F150 plow truck length wise and with a plow it covers two zip codes. Even if I lowered it, it would still be a tall vehicle for Mom to get in - plus, he sees trailer dragging duty pretty regularly..

Then there's the wife's 2012 Focus which would collapse if I put anything heavier than a keg of beer in the back let alone a hitch with a 300# beaver tail..

The TJ with the Western Plow is just a little shorter than the standard cab F150 is without a plow and is maneuverable enough to navigate my two driveways without having to get out the snow blower to boot.

Here's a pic of the TJ for you guys..

Oh and a link to one of my project cars that I really need to get back to working on::
Http://www.GT-Forty.com

So - yes, cutting coils would lower it but would also stiffen the ride quite a bit - so maybe I'll pop the springs out and move the suspension through the range of motion and see if there are any bump steer or driveline binding issues..
If anyone has any ideas on the ratings of the springs, I could think about converting to coil-over shocks..

She can't lift her feet over the threshold of the tub without help, but yes, she can get in. If the truck were a couple inches shorter, it would be a lot easier..

You are in my neighborhood! From Pine Island over here.

Yeah, nobody here ever talks about lowering a Jeep, but nothing should stop you from modifying it to best suit your needs.

Hi neighbor!

Nah, I view all of my vehicles as my own means of expressing my individuality and haven't let public opinion sway me much from the direction I think I need to go..

Basically what I was hoping for was to find out about any potential suspension or driveline geometry issues if someone had already been down the same road..

I'm not looking to slam the little truck like a low-rider..
Just drop it a couple of inches..

put an air-ride suspension on all four corners.

Looking into that right now...

Wondering if there is a system out there that replaces the coil springs altogether..

Thanks again for this and the part numbers..
After checking their website, it looked like conflicting information. The vertical columns showed approx front and approx rear lowering, while the text to the left where it calles out the STAGE of the spring, it says Raising Spring. So I called there and talked with a fellow named John who insisted that the information was not conflicting and that they were a raising spring only.. Well, I wasn't about to argue the formatting of their website with him - it looks like that was a dry-hole..

How about mounting an electric step like they use in motorhomes under the tub. They make them in singles and doubles and it could be wired to a door switch so it would extend automatically when the door is opened.

I like this idea. it will give you the best of both worlds, ability to lower jeep to get in and out, without killing the jeep qualities. But you still have the tall lip in the tub to worry about. You might be able to find a fabrication shop that can modify the tub so it is not so tall. a good fabricator can do almost anything.

Although most people are saying to not do it, I would say do what fits your needs best. In the end you still have a Jeep. To be honest the fact that you are looking for solutions shows that you have love for your jeep. Most people would just get rid of it for a more suitable vehicle.

Good Luck and keep us updated.

One of the best ideas yet. How about one step that looks like a stirrup (sp) that grabs the lip of the tub and hangs down a good 6 inches or.more?

Just an idea, why don't you teach your wife how to drive a standard, my 85 year old grandma can drive standard no problem, and its really not that hard to learn. I know you said you want to thin the herd, but if its perfect for your mom, I would think your wife learning how to drive the s10 is the best and cheapest option here IMO,

I taught my wife how to drive a standard 36 years ago when we first got married.. She hated it and still does.. I tried the old routine of giving her a car with a standard and saying - it's this or riding a bus! Guess who went to the bottom of the pussy list then!
The fact that she refuses to drive a standard trans vehicle is her only fault. After all these years, I just finally threw in the towel on the notion of ever changing her.

I am back looking into not just air bags, but full air ride suspension now.. I rather like the notion of being able to adjust the ride height of the Jeep. Pull up to Mom's place, let the air out, get Mom and scooter loaded and then pop it back up to the proper height..

BTW, fabrication isn't a problem for me - I have a pretty well equipped shop with welders, lift, Mill, Lathe, etc.. It's just a "TIME" thing.. I would rather use a proven "bolt-on" solution if available..

Here's a pic of my little buddy I named O'Doul.... I'll miss this little guy... Sniff...

Instead of cutting springs, get the springs from a 2x4 wrangler they sit lower.

Sit lower by what means? Jeep didnt make a 2wd TJ only on the JKU. Which I still dont know if that would work considering that stock JK's sit higher than TJ's (taller springs). So i would assume that the 2wd JKU spings wouldnt be much shorter than the TJ's factory springs.

Didnt look at any of the specs but just a quick thought. Big Foot seems to be wanting to keep the capabilities of the Jeep too. I would say that an air ride suspension would be the way to go and make one awesome ride.

I have seen airbag suspension kits, but these have a LIFT range from 4" to 8" I haven't seen one to lower it...
