Default BDS 8.5" long arm lift on 99 xj

thinking of doing the 8.5" long arm lift never went this high before what are the cons on this lift, i know i need a longer drive shaft a slip yoke eliminator and so on, jeep is gonna be put to the hardest rockcrawling and biggest mud holes and pits as well as my daily driver, i thought the 8.5" bds would be a great lift for this, just wondering if its a good choice and will do what i need, or is that too high, i dont want to be snaping drive shafts every 20000k and i dont wanna have problems rockcrwaling and soo on, any adive from you guys will honestly help thanks

I am no expert neither do I have any experience but I don't think an 8.5'' lift would be a good DD

dont plan on using 4.88's then. all the ring/pinion shearings I've witnessed have been with 4.88's and too big of tires (aka anything bigger than a 35x12.5 on a D30). the iroks are too heavy

stock axles are just not going to give you the performance you're looking for with that tire/terrain. hope you reconsider and swap out the front

also, an 8.5" lifts lack of stability in off camber is appalling. if you're going to do it you'll definitely need high steer. theres only one or two builds on here where an 8.5" lift was set up properly (and by properly I mean expensively)

personally if I ever built a real mudder it probably wouldn't be a cherokee
anyone got a link to that black cherokee with flames painted on the side? that'd be a good reference for the OP

Exactly if your gunna do it do it right if your going that big I would say 4 link front and rear probably on coil overs with narrowed one tons but there's probably 15k easy if your using qualify parts.

actually I'd go opposite on a mud truck. nothing wrong with using leaf springs front and back, 1 tons, and 5" back space wheels to narrow it up for mudding. then you can run the 39" iroks instead of those wimpy 36's

honestly for what you're doing, pick a different design and different axle. a mud truck can be clean and not hack if you put some thought into it. the 36's would be better for anyones off road applications but your D30 just wont be strong enough. use this build to get some ideas. now thats how you get muddy. swap your axles, run bigger tires and leafs. easier to get high steer and cheaper to have a suspension thats fine for mud and a bit of rocks

he's running 8"+ lift and 38's. need clearance on the rocks? thats a laugh. flat belly/good skids and you'll slide right over the rocks. you'll hang yourself up the most on the differentials and hit your drivelines on 35's. so for rocks 8" is completely unneccessary. actually that tall a lift and if you go off camber through a tight squeeze, you'll actually be more likely to drag your roof rails and quarter panels across rocks. blow out windows and such

D35 is the worst POS axle that ever came in a cherokee. you'd be good running a 44 front and a 9" rear. but it sounds like you're aiming for a hacky show rig. I no can help you sir

do you think the 6.5" lift would work out better and just run 35" tires because that was the first plan

You are gonna need a rear axle and front axle swap to play hard on 35's nothing above a bb is cheap or easy things take time and money

Fast and easy only come with hack jobs, since you don't want to listen to our replies, we really can't help you. Best bet is to just do what you want and search enough to figure it out. We have explained already that 8.5" is too tall and for 36" you're going to need a new front axle.
