Just ordered a 4.5" lift for my 90 xj. Anything special I need to do with this other than start spraying pentrating oil on all the bolts.

I am going to put 31" buckshots on a 15x8 with 4" backspacing. That should clear good I hope.

 

I put my rc 4.5" on about a month ago its a nice lift, but ur gonna need more than penetrating oil, mines a 96 and control arms sucked i used a torch on almost everything, i just cut the control arms, the front probably takes the longest, rear wasnt too bad, rear shocks where tough to get out, but make sure ur rear axle is aligned properly and tighten the crap out of the u bolts. and you will need an alignment after for the front, also the track bar u have to drill a new hole just make sure u drill it properly, good luck! post some pics when ur done

 

does it have swaybar disconnects? If so when you drill the holes for them that they will be straight up and down. So that when it is disconnected there will not be any binding or the pins will get twisted up and pulled out.

 

What is it going to do to the alignment?

 

your gonna have to get an alignment lol. i put the 4.5 RC lift on my cherokee and i needed an alignment when i put it on. my tires toed in

 

Ya when I was driving straight my steering wheel was upside down and had a bad pull

 

i also purchased this lift and am installing this week

 

+1.....your changing the geometry of the suspension by installing the lift, so you need an alignment to get everything back into spec.
