Hey Rancho guy!
I was incorrectly shipped a 4dr 2" Sport lift off of an amazon vendor.
I installed it on a 2dr JK.
Like KJeeper10 said, the 4dr kit comes with a 3/4 In Spacer for the rear axle and the 2dr kit comes with a 1.75 spacer.
Do you have a part number for the 1.75 Spacer WITHOUT buying a complete front/rear kit????
If so i havent found it yet.
