springs

my guess would be a dodge durango or a dakota. but im pretty sure that both have leaf springs in the rear unlike your zj which has front and rear coil springs.

go to ironrockoffroad.com and do this http://www.ironrockoffroad.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=IROR&Product_Code=IR-Z_3LK&Category_Code= or you could just do a budget boost

the dodge dakota 4x4 with the sport package has springs in the rear end but they are only about 2 inches bigger than the cherokee i was going to do the same thing with my wifes 98 grand cherokee when i was getting ready to trade in my 97 dakota
