Advice on Rough Country spacer lift

Hi all,
I have tried searching, but only came up with a few results, the search on here filters out over half of the words I search.
That aside, I have been wanting to put a moderate lift on my jeep and I have found the Rough Country 2.5" Spacer lift kit. Who all on here has experience with this kit, not second hand or further (cousin's girlfriend's mom's uncle's great-grandson said...). I would like some pics if I could get them and yes, I read about the light that someone had from the sensor. I plan on using a coil compressor so I don't have to push the axle so far down.

Questions:
1. Is this kit decent for the price?
2. Will I need to align afterward?
3. I am not extremely familiar with the suspension set up on these, last 4x4 was a Bronco (no track bars and crap). Will this move the axle(s) further to one side or closer together or leave them exactly as they are?
4. Will this truly give 2.5" lift or 3" front, 2" rear?

I read the instructions and they seem pretty straight-forward, except adjusting the draglink. I read another post on here about him not needing to do it all. What is that all about? From What I understand the draglink aligns the wheel(s) L to R, is that correct?

Thanks in advance and sorry for having a newb question, but it just seems like a lot and everyone on here is generally very helpful.

I did the Teraflex spacer so as far as price and quality of RC, I let others comment. I did an alignment after my lift of 2.5" up front. Wasn't much off but off a little none the less and you will need to check that steering is on center afterwards. A spacer lift gives you exactly the lift it states. Those getting different size lifts are from coil lifts and is directly related to the stock coils you have in. But since you are not replacing the coils then the weakness or stiffness of the stock coils will still be the same.

Cant comment on the price, but can elaborate on some other bits for you. As rics1997 said, a spacer lift will give you exactly the lift it states as it moves the mounting point of the spring.

If you crawl under and have a good look at the setup you will see that the trackbars front and rear are already not parallel to axle/ground, so lifting the vehicle will increase this angle and shorten the horizontal distance between the ends, effectively moving the axles sideways. At 2.5 in lift you can expect the axles to move approx 6mm to the side, in opposite directions to each other. Not a lot but noticeable. If you want to bring them back centred I would (and have) fitted adjustable front track bar and an axle mounted rear track bar lift bracket.

Since the control arms are also on a slight angle, lifting the vehicle and increasing the angle of them will slightly pull the axles together, but not significantly noticeable unless you want to increase tire sizes to 35's or over then they may hit. In this case you will need to fit adjustable control arms to stretch them back out a little, but not too far without extending the bump stops otherwise when the springs compress all the way the axles will push too far out and the tyres will hit the bumpers!

The drag link is the connection between the steering box and one wheel. When the diff pulls sideways if the steering box does not move then it forces the wheel to turn to the side. To keep the steering wheel straight you have to alter the length of the drag link by the same amount the diff has moved to the side - or fit an adjustable track bar and swing the diff back to centre.

This is the only alignment you will need, as toe in, caster and camber do not change. Caster may need to be looked at, it varies vehicle to vehicle, but should be OK at this height. If it needs to be increased (the caster will decrease as it lifts due to the different lengths of the front control arms) then ideally adjustable control arms should be used, at worst cam bolts can be fitted but I am not a fan of them.

Not sure on the instructions supplied, but a few pointers - make sure to loosen the bolts on both ends of upper and lower control arms, and remove the diff end bolt from the track bar, drop the bolts from the sway bar links, drop the bolts holding the hard brake lines and remove the clips holding the ABS cables tight. Remove the lower shock bolts (or drop the shocks if replacements or top spacers being used). Jack up from the diff getting the wheels at least 3 to 4 inches off the ground then chuck some stands under the chassis just behind the lower control arm mounts. remove wheels, drop diffs and pop the springs out (quite easy). Pop the spacer in as per instructions, pop the spring back in (making sure to put the front bumpstop extenders in during this is you have them) then reverse what you just did, but before refitting the track bar loosen off the chassis end so it can drop down without distorting the bush (leaving it done up before dropping the diff holds it up out of your way). You will prob need a hand to push the diff across to get the bolt to line up.

Most importantly wait til the vehicle is back on its wheels on the ground, bounce it up and down then torque the control arm and track bar bolts to spec. These must be released and redone so that the bushes find their new centre for this height. Releasing them before dropping the diff allows the diff to drop easier to pop the springs out.

I would also be looking at longer sway bar links as 2.5 in lift is really pushing the limits of the stock length.

Hope that helps some, have spent the last few months discovering all this the hard way! I should add that I am now pulled the springs out 4 or 5 times over the last 6 months on my driveway with a trolley jack and a pair of stands, and mysteriously disappearing mates just as the work begins

As mentioned, align it after, and yes it will shift the axles, not enough to make much difference, and it can be adjusted if you feel it's necessary. I too am not familiar with the RC lift, we have the 2.5" Teraflex BB on ours. I'd look at it. It's a great price, but you'll need every socket known to man to install it Each side has different size bolts. $314 shipped from Northridge 4x4....

I have the RC steel spacers ONLY, I've heard too many bad things about the shocks-I paid $99 bucks almost two years ago for the 2.5"-2" spacers and shock extenders, which I didn't use, cause I used different shocks

The steel spacers will last much longer than YOU, but I'm not in favor of the shocks-

2. Will I need to align afterward?

Every jeep is a LITTLE different off the assembly line, Mine didn't need track bars or alignment, course I've got diff. fenders to !

3. I am not extremely familiar with the suspension set up on these, last 4x4 was a Bronco (no track bars and crap). Will this move the axle(s) further to one side or closer together or leave them exactly as they are?

You'll have to be the judge AFTER the install-2" lift doesn't do much-

4. Will this truly give 2.5" lift or 3" front, 2" rear?

--2"-thats it and it will level the jeep-

I read the instructions and they seem pretty straight-forward, except adjusting the draglink. I read another post on here about him not needing to do it all. What is that all about? From What I understand the draglink aligns the wheel(s) L to R, is that correct?

They're good instructions and you will HAVE to ADJUST the sleeve on the drag link !

Thanks in advance and sorry for having a newb question, but it just seems like a lot and everyone on here is generally very helpful.
It's not a real difficult job, but you NEED JACK STANDS/JACK/ TORQUE WRENCH AND MM TOOLS-there is an element of danger, with 4000 lbs of jeep over you !

Right on !

Good luck

Here's mine with the RC 2.5" lift

Good luck

Ok, thanks everyone. I think I'm gonna go for it. I am getting the shock extensions to keep the stock socks. I am only going to go with 33s, not 35s for a long while. I will replace with new ones later. And end links. And trac bars. And CAs. And a bigger lift. And so on...

I have the RC 2.5 lift kit and it comes with heavy steel spacers that go on the top of your coils.
The instructions are ok but fail to mention to disconnect your wheel speed sensors plug from the inside of the wheel hub BEFORE you push down on the axle to remove the coil spring.
When you reinstall the spacer and try to put back the coilspring you have to push the axle even farther down to get it back in.
Rent a coil spring compressor from an auto store and DO NOT ATTEMPT by yourself like I did and broke the wheel speed sensor that cost me 218 dollars when I took it to the dealer.
I really like the simplicity of the RC 2.5 spacers and it gives it a nice level stance on my 4 door.
