I am looking into a LA lift kit from Iron Rock Offroad and wanted to get your opinions on a 5.5" lift kit vs a 6.5" lift kit? I want to run 35x12.50" tires. I will also be running a Dana 44 in the rear and keeping the Dana 30 up front. I'll also be upgrading the steering system, axles, lockers, driveshafts, and transfer case. As I understand 35" tires and a lift over 4-4.5" in height starts to cause problems. We don't like problems. lol
So there it is in a nutshell... Is there really that much of a benefit of running a 6.5" lift over a 5.5" lift? Is going with a 5.5" lift better simply for the lower COG? I will be using it mainly as a trail rig but will drive it on the street fairly often and drive it to the trails. Washington, Arizona, Colorado, etc. I want it to be capable anywhere I want to take it.

Bastard pack vs add a leaf to get 3 inches. What are the pros and cons for each? Which one is better ride and longer lasting?

Couple of questions gentlemen, before I spend anymore money.
1st questions is... Soo far my xj sits 3 inches higher than stock and of course my front axle is pushed over to the driver's side. Before I re-drill the t-bracket I thought about purchasing 4.5" front springs and just adding additional leafs to my rear packs that way I can just drill the t-bracket once and not lose rigidity. Onto the question, besides the front springs, rear bastard pack, what else would I need to make this all work correctly? I know I need rear axle shims and extended brake lines for all four corners.Also, would I need aftermarket front lower/upper control arms? If so, what size, adjustable or not, and anyone got any recommendations?

2nd question is, what size tires would I be able to clear with a 4.5' lift but without fender trimming?

3rd question is, I've got a D30 axle up front, N231 T-CASE, D35 rear end with upcountry lsd, and a 5 speed trans. I'd like to swap the 3.07 final drive for 4.10 final drive but one of the techs at work said I would tear up my transfer if I went with the 4.10's. He said that since gearing in the rear diff and front diff are not the same I'd trash the transfer case. Is this true? Would I need 2 sets of gears?

Any help is greatly appreciated!!!!!!!!!!!!

IMO As long as your "upgrading" everything you say you are than go with the 6.5"... or more if you want 35s the right way. I'm running 6.5" w/long arms + 2" spacers with 35x12.50 and don't have a bit of rub. Although without the spacers i might (if the shocks would even let me). With 35s though you'll want to gear it right, I have 4.56... I'll be doing 4.88s - minimum - when I get my dana 44s.

One note on 8.5": the shocks that will come with the 6.5" kit will be not be long enough after adding 2" spacers. I had to run two different part# in the rear because of the way the axle tilts the perches... Which is no problem.

Locking that d30 with 35s is where your problems might be... So I hear.

You need to have same gears running in both front and rear axle. Which you can buy new gears and upgrade. Currently I run a 4.5" lift. I have new upper and lower control arms, both adjustable, new shocks, coils, adjustable track bar and you may need a slip yoke eliminator. I currently don't have one and I get very little vibration at all, mine drives just as smooth as my buddy's stock ride height. But I have heard of people with vibration issues. Also I run 31's no problem and could go 33" but no clue about any bigger

How will I benefit from new lower and upper control arms? Also, would you recommend just re-drilling the t-bracket or buying an adjustable track bar? The reason I ask is I don't really want to worry about the bar loosening up every soo often... Any problems with your tbar?
