RE 7.5" coils HURRY!

wannabe said:
its a 99 so i got the 8.25. Have read in quite a few threads that the 5.5 ends up at around 6.5 up to 7.5 but usually around 7ish, do a search. Just not sure if the 5.5 will be enough to clear 35's with the trimming i am doing.

5.5 will give you around 6-6.5 not 7" thats exaggerating

As far as gears i used a couple of the gear ratio calculators to make sure they were all working correctly and everyone i tried ended up bein just a little lower than stock and I am fine with that. I not goin to pay another couple hundred to swap axles in the future if it be comes a problem then I can deal with it but for now Ill be locked f/r with 4.56's and 35's its cool. Just want to get peoples opinions on the pictures of the trimming to see whether on not i should go with the 7.5's and blocks to give a bit more clearance and up travel. The XJ in the trimming thread is running 5.5's. thankx again.

I have 4.88s and both 33s and 35s, the 33s are perfect, but I seriously wish for 5.13s or 5.38s when I have the 35s on.

You have the axles to do it in. That is pretty low for a dd though, even with the OD. Heah, did you get your ARB hooked up yet with those special switches? I'm having problems with mine still and the wiring. I tried using both the #1 & 2 switch for my front dana 30 arb.

this is my daily driver (drove it from Michigan too) and the 33s and 4.88s are perfect at all speeds up to at least 80 (as high as I've had it).

i got the switch done, i like the simplicity of doing it this way.

I have 33" tsl radials on my 94' wrangler with 4.88 gears in the ford 8.8 and dana 30 and love the power. I have a 95' 4.3L chevy vortec motor & 4L60E tranny with overdrive so I'm still just under 3K rpm's at 80 mph or so. I'm going to revist my wiring today when I get off of work and hook the ignition cable to my pos battery and see if I can get it to work. This thing is really turning into a pain. I need to get this to work for next weekends Rubicon run.

Will everyone who places a post take a second look at my original thread and especially look at the trimming link that I have on there, that is all I am willing to trim right now. Down the road I will go flareless but not for prob. a couple years. Thankx to everyone.

You will be fine with that amount of trimming. If you still rub, just add a little more bumpstop.

You can't tell if 35's will fit on your suspension with that amount of trimming. The question is more complex than that...factors such as rim backspace and width are crucial to flare contact. However, it looks to me like the people who are running 35's on 5.5" of lift have done more trimming than what your pictures show. I've never seen an XJ on 6" of lift with 35's with a full range of suspension motion that wasn't severely trimmed.

If you want to keep a relataively clean look, and you want to run 35's on 15x8 rims with 3.75" backspace in a typical setup, then I'd get the 7.5" coils. I think you'll find it easier to fit and won't get into having to limit up travel to avoid body and tire damage.

Either way, with 35's you are throwing caution to the wind IMO, so pick the lift and you'll end up making the rest of it work. I wouldn't spend too much time putting parameters around body trimming for an XJ that *needs* 35's...trail damage is likely to obscure your fine trimming work at some point anyway :D.

What are you trying to accomplish? Are 35's the biggest you'll ever go? Do you want as low a lift as possible with as much trimming as possible? What concerns you with the taller coil, understanding your trimming concern with the lower coil?

I just swapped out the 5.5" coils plus spacer for the 7.5", and the difference is about 1.5" max, FWIW.

I like the 7.5's better. They are a bit stiffer. I don't know what the bust is on the 6" XJ lift vs. the 7"-8". I haven't found any decrease in stability or performance and it is simply easier to clear larger tires. In my experience, 7-8" on an XJ is a real sweet spot (if you are willing to move way beyond bolt-on stuff), and more so than 5"-6". Regain stability through track width.

I spent a lot of time and money playing around with lower lifts and never found any advantage....although I was shifting between 5" and 6.5" at the time.

My rig right now at 8" is by far as stable as it's ever felt since I lifted above 3" 4 years ago, but maybe that's as much due to stiffer springs and Bilstein shocks as anything. My point is that this question goes way beyond "what lift spring should I buy?". Height is only one piece of the equation.

Yes 35's are about as big as i plan on goin for a long time and if i decide to run bigger i will be at a point where hacking the fenders will be fine. What do you mean by moving well beyond bolt on stuff? I will be running a custom LA setup and RE brake line xtra heavyduty trackbar and bracket SYE etc. Is there something else i should be thinking about. I will also be running bilstein 5100's what do you think I plan on ordering tonight from fullsizexj. You cant beat his prices cause DPG and BOR refuse to answer there damn phones for days on in.

Ya im not willing to trim anymore than that for NOW. Dont want to deal with the ahole pigs around here for not having flares or tires stickin out too far. Your idea for rim size is right where i was planning. I have a buddy/the guy that is building my LA kit that designes all the beadlocks for trailready and he can hook me up with a set of his with 3" BS that i would run on traildays but i thru a thread up awhile ago talking about that and a few people were saying to watch out due to excessive stress and wear on the bearings and hubs etc. What did you use to match the rear to the 7.5 coils, Blocks? thankx

What are you running for disconnects I ordered a set of the quicker discos but the spec's show that they work for up to 6" of lift is there a way to mod. them that i am not seeing. thankx

at 7.5-8" adn 35's i would look into doing somekind of OTK, or beef up your stock steering. as for the JKS, RE sells swar bar relocation brackets. use the relocation brackets and JKS QD and you won't need to modify anything.
 
I have considered an OTK setup but i need to learn more about them who sells them how much whats involved etc. I just want to get the thing in the air and go play. Im thinkin that i will prob go with the 7.5's because i go to the dunes alot and dont want to limit my up travel that much. One more thing that i thought about is it necessary to run some sort of mod (bar pin elimators) to run the bilsteins that i plan on. Have read some about them but still not totally sure about the purpose or need.

It's silly to talk about BS causing stress on the bearings when what we are doing is centering the wheel on the hubs more than they are with the stock 5.25" BS.........neophytes.

However, if you want to run big tires with a minimum of trimming it's important to keep the tire tucked inside of the wheel well, meaning roughly 4.5" of backspacing. 3" will cause you problems since the tires will stick out too far, and more trimming will be required for them to clear. Just so you know, the flare doesn't get in the way much except at the very bottom. I see people raising the flares all the time, but I never raised mine, they were in the stock location with 6"/33's and 7.5"/35's, and I finally removed them when I went to 37's. All the trimming that's needed is inside and on the bottom of the wheel wells, and is hard to even notice if you don't already know XJ's.

You'll need springs for the rear, can't do very much with blocks, and add-a-leafs will give you a stiff ride.

You don't need anything in the rear for Bilsteins, but you'll need a new mount for the top in the front. There are some companies that make a good quality nitrogen gas charged shock with a post top mount, check out Doetsch.
 
thankx goat. I wasnt planning on raising the flare, i should have mentioned that earlier. I am planning on just trimming the flare and sheetmetal in the same locations that eric did.
 
What springs do you have in mind. I figured i would just run the re 4.5 leafs with their 1.25 shackles and 1.5" blocks but if you have better info let me know as i plan on ordering from fullsizexj tomorrow.

i do that, and the rear sits way taller than the front. i also have a BPI bumper with 9000lb winch
