Hi Guys. Newbe to Jeeps and the Forum,, so first post , hope you guys can help.

I've just bought a 1998 Wrangler. TJ
From going through the previous owners file on the jeep i found the list of parts he purchased for it from Morris 4x4 Centre.

He purchased
RS-6416 and RS-6417 Rancho front and rear coil springs.
52087835AB and 4897567AA front and rear "Blue" gas shock absorbers.
RC-1157 Rough Country 1.25" body lift kit
RC-1156 Rough Country 1" motor mount lift

From what i can see this is all fitted and working perfectly, but what I'm looking to do is raise the jeep about another 2". This is for looks only as the jeep will never be off road but i want the ride to be as comfortable as possible as most of my driving is on bad old bumpy roads.I currently have 29" tyres but will upgrade later to 31" but no bigger.

What would you suggest is the best way to go without spending a fortune.
Cheers guys.

That is a nice looking TJ. If you are looking for an inexpensive, but good quality suspension, I don't think you'll be able to find it. You always get what you pay for. I wouldn't lift it just for the looks, you'll end up wasting your money with an uncomfortable suspension that will make your TJ very unstable.

For what I've heard, Rough Country suspension systems are not good.

Seeing as you're only looking for 2" you'll want to check out the OME kits from DPG Offroad. Everyone keep saying to talk to the owner, Dirk, and he'll see you up with everything you need.

Just know that when you change the geometries of a correctly engineered system you will mess things up. Parts might wear faster, angles are off. What I'm saying is initially you pay for the lift, you might need to pay for more components to fix what you changed.

It already has plenty of lift to run 31" tires. Why change it? Although I generally wouldn't recommend Rough Country products, we are only talking a body lift (spacers), and a motor mount lift (also a spacer block).

You may want to get out a tape measure and measure the springs. Stock spring height is 12" in front and 8" in the rear at ride height. Anything over that would be suspension lift height.

If you do decide on a 2" suspension lift, the recommendation above for an OME lift from Dirk at DPG Offroad is an excellent one.

Always good seeing other red TJ owners :p

I run 31's on my TJ with a stock suspension setup. A 2" lift will certainly clear 31's with no problems. The downside to it all, is how much you'll be spending to have it shipped over to you.
Look into the Zone kits...I'm planning on running a 3" with 31's or 32's. Should be a pretty easy install IMO.

Thanks guys, I taught if I stayed at 2" or lower it was straight forward as it didn't effect the geometry of the suspension or require any further changes.
I was thinking of something like the Rough Country 2" suspension spacer lift with the Premium N2.0 shocks

Any ideas what something like this kit is like.

OP, not sure that you have realized but you currently have a 2.5" SL along with a 1.25" BL from the part numbers given, which is way too much lift for 29's and usually reserved for 33's. Not sure why you would want an additional 2" to your current lift with just 29's or even 31" tires. Unless the current ride quality is not to your liking, I would keep the lift and get 31's or even 32's if your gears are adequate.

I didn't realise I had a 2.5" Suspension lift as the 52087835AB and 4897567AA gas shock absorbers are sold on Morris 4x4 as a standard shock or direct replacement for the original. And when I measured the springs I have 12" front and 8" rear which I taught was the stock height.

Since the 31's will fit without a lift, get those and drive it a while. Mine is stock on 31's...I like the look over stock, and even though I will lift it eventually, it does what I need!

Ok new update:
I've just spoken to the previous owner, the springs on my jeep are stock as he never got around to fitting the Rancho springs, but I can have them if I want.
Should I take the Rancho springs and just change the shocks etc or should I just start from scratch.

Personally, if you have plans on sticking with your current 29's or upgrading to 31's, I would stick with your current setup of stock springs(or replaced with new OEM springs if sagging) and the 1.25" BL.

I think adding the Rancho springs would be too much lift for your tire size and possibly introduce driveline vibes along with a worse ride. You will also have to add in the additional costs of longer shocks,bumpstop extensions and swaybar end links.

I've heard different things from different people about spring lifts. Yes, they are superior when compared to hockey puck spring spacer type lifts - but they do introduce a whole world of different problems including additional parts and tuning to get it right. If your OEM springs are OK I'd just go with the body lift and motor lift. I've got 31's on a stock suspension and flat fenders, they don't rub at all (except for the LCA's). One thing I've learned about Jeeps is the suspension is very picky and expensive to modify.

OMG !! Thanks Guys.
I taught this was as easy as a few spacers and change the shocks.
I'm even more confused now.

I don't really want to leave it as it is because I'm convinced there is something not right. When I sit into the jeep it leans to one side slightly and doesn't level out, I'm not a big guy so I'm sure it shouldn't do that.

I was thinking today that maybe it had something to do with the 52087835AB and 4897567AA shocks being used with the stock springs. Are they possibly designed to be used with the Rancho springs as they are higher.
