what size lift for the rear? w/pics...

I just installed some 30x9.50's Dunlop Mud Rover's on the 'ol XJ this weekend. These things will go though alot of sh*t. My question is, I found out after measuring that the previous owner put a 2.5" lift on the front and the rear is stock(19.5" front/17.25" rear). I am going to get a Rusty's add a leaf for the rear, but need to know what size to go with. I was initially thinking of going w/the 2" but after measuring tonight, I'm thinking of going w/the 3.5" add a leaf. What do you guys think? Sorry the pics are @ night.

Thanks in advance guys. This forum rockseace:

Few more pics....

Instead of doing an AAL from rustys, why not use a stock S10 main leaf, or a Dodge Dakota main leaf, cut down to fit in as an AAL? Might be a cheaper, easier route. Could add a shackle too.

^^^^I've heard good things about the add a leafs from Rustys, and the nearest junk yard from here is about 50 miles away. Just don't know what size to go with. 2 or 3.5"???

I got the AAL from rustys in my 3" kit, Its nice never had a problem with sagging or anything after I installed it. Evened out with the front perfectly. I would consider getting the entire spring pack though. More money but new springs are much bettah
