Lowering XJ

[highhilleer]

I've also installed the front air dam from a '91 GMC Jimmy. This has reduced front end lift to make the Jeep noticeably more stable at speed and in crosswinds.

I have really studied your web page and saw that you added an air dam but did not know the source. Did you do a write up that I missed???

Your page is inspiring. I was looking for a vehicle that responds well to mods and your page is one of the reasons leading to the Cherokee decision. I haven't driven my Cherokee 10 miles yet (damn work) but am itching to start the mods.

But since you mention AutoX...I'll do it


I've also had the thought to build up a ZJ running a 2JZ (Supra engine for those not in the know, but that's a topic for another forum Is there a NAZJA? hehe)

XJ might not be allowed to autox, because it is an SUV...and could roll. I think that is a local rule, not sure.

Supra engine sounds logical to me. XJ automatic is nearly the Supra tranny, and they are both inline 6's. Remove the 200hp-ish 4.0L and install a 320hp+ turbo 3.0L. Is the 2JZ the one that can handle 500hp mods easily? If nothing else, do it for the sound. I'd love to have a Jeep that had a 7000RPM redline and a blowoff valve. PSHHHT

True, didn't think about that. There's a special Truck/SUV class in RallyX...but if possible...I WILL

And the 2JZ can handle well over 1000hp with forged components...but yeah about 500 or so on the stock bottom end...It would be a fairly stright forward swap in reality...if I had the money to do it, I'd consider it, but right now I'm just a starving student...

And also, my 4.0 (well, 4.6...) will have a 7000rpm redline and a blowoff valve when I'm done

my new life goal is to put a 2JZ into an XJ.:idea:
Edit: sorry, didn't notice this is a 4 year old thread. Not sure what the R&R's are for bumping old threads, maybe it needs to be resurrected!

well i happen to have stumbled in to this and i want to see what this project turned into.i too have pondered a nasty street jeep.

 

[sharq]

ive never seen a lowered XJ that i liked. anyone got some pics of it done right?

 

[seanyb505]

Said cut coil springs and sagging rear end. About a 1.25-1.5 drop all around. It since has 16" libby rims, and will soon have 255/55/16 tires to complete the look.

 

[gradon]

Here's mine w/ the 2" drop:

 

[96_XJ_Country]

that looks sweet man, did you cut the front and take a leaf on in back?

 

[gradon]

I bought custom springs from Springworks in Cali. If I were to do it again, I'd chop up some new f-150 or t-bird coils for the front and maybe attempt a SUA with some new HD leaves for the rear.

 

[seanyb505]

Went and took a pic with the 16" KJ rims.

[96_XJ_Country]

sorry, what exactly is an SUA?

 

[seanyb505]

Spring Under Axle. In our XJs the leaf springs rest on top of the axle shaft. If you relocate the springs to be under the axle, it would sit about 4-5 inches lower.

 

[sharq]

MJ's are SUA. if you score a rear end from one it should be a direct swap.

4 or 5 inches a whole lot of drop. what size tire would you have to run for it to fit. seems silly low.

 

[seanyb505]

You would have to raise it 2-3 inches, so the total drop would be 2-3 inches. You can only go so low on front or youll hit the oil pan, so you would want to only match it in back. I thought the shock mounts are different on an MJ....Or there is some reason you cant use them. I could be wrong.

 

[gradon]

Yeah 5-6" is too much, which is why I ordered 2.5"(but got 2"). 3" would have been perfect(for the way I want it to look). I am also running 27" tires(255/60/15) so that makes it sit 1/2" lower and makes the gap b/t tire and flare 1/2" bigger as opposed to a 28" tire.

 

[96_XJ_Country]

seanyb505, did you order custom springs for the front AND back?

 

[seanyb505]

lol If by custom you mean XJ leaf springs will sag when they get old than yes. The rears just naturally sag. In time I will look into SUA or actual lowering springs to get a better ride. Leaf springs so soft they dont keep the car at ride height arent great for carving corners. Front I just cut the bottom coil off the front spring. I didnt even take it off the Jeep.

x2 on both, to do any more you would need a dropped front axle and maybe slightly moved upper control arm mounts for oil pan clearance.

this is a front axle someone made custom for a v8 conversion drag xj. its on another forum and I can get the link tomarrow for the rest of the build.

 

[96_XJ_Country]

sorry, i meant to ask gradon about the custom springs
