Definitely has to come out, not sure what leaf you would replace it with to match the other side though...

 

I recently obtained a 1999 XJ Sport, and started doing quite a bit of research on lift kits, rims/tires, and other aesthetic improvements. I've decided to go with a 3.5" lift, with 31x10.50x15 Cooper STT Discoverer Tires, and 15" American Racing Baja rims. Regarding the lift, I needed information about the many different types of lift kits. I won't be using my XJ for mudding or climbing often, if ever, but I've somewhat fallen in love with the look of the lifted XJ. I don't know if I need to get a "Suspension System with Leaf Springs" or if I can get away with the cheaper "Add-a-Leaf" option. Also, after buying this lift kit, will I need to change anything else about my vehicle? If so, what are some affordable items I could purchase?

 

I would never recommend an AAL kit unless they were working with a brand new leaf pack. It will sag within a year and you'll get stuck buying new leaf packs anyway.

 

A 3" on 31's is, in my opinion, the perfect dd you can have without changing a whole lot. You shouldn't need much for steering, driveline, or gearing if you're going to keep it on pavement. Plus it looks pretty sweet.

I've had both. Aal, and full leaf packs. Definitely go for full leaf packs. The reason an aal is a poor choice for a first time lift is this: most often the condition of the leaf pack isn't enough to help the aal support the weight of the vehicle, so the aal suddenly has to support it all on its own. That's why they sag back to their original height quite quickly. Full packs are the way to go.

Your shocks and shackle angle are the main factors that determine ride quality.

 

Have 3" lift on 2000 Cherokee Sport. Want 31x10.5 tires. I'm figuring 15x8 rims but what backspacing is appropriate?

 

You will need 4" or less to keep the tires from rubbing on the lower control arm. You will probably have to trim the flares a bit.

 

3" and 31s is a good lift, and15x8 is the ideal width for a 31x10.5. As Swirl said, 4" of BS is pretty standard.

 

If I do 3" could up front, can I just build a bastard Pack for the rear?

 

Yessir

 

Id reccommend it! Highly modular, and much much cheaper.

 

3" coils. Lol. So would it be better to bastard pack, or just build add a leafs? I'm obviously tryin to build the cheapest thing I can. Just want it to be safe and not tank like.

 

Bastard pack, just make sure you get a quality center pin, clamps, and new u bolts.

 

^ which 3" coils do you recommend?

 

Rubicon Express

 

What do you plan on doing with your jeep? Any bumpers? What shocks are you running?
