Thread: Mustang II IFS, 4-Link, tire and rim size

Tweet

First let me warn that I have quite a few suspension questions.

Has anyone installed a Mustang II Ifs kit on their trucks and was it worth it? What brand would you prefer? What is the bolt circle?

Does anyone know where I may be able to get a 4-Link rear suspension for my 2wd 1979 F-100?

Is there an adapter to change by bolt circle from 5x5.5 to 5x5?

What is the widest rim I can fit in the back without having to tub the bed? I want to go with 31x12.5 Mickey Thompson Sportsmans on 15x12 Billet Specialties Vintec Dish rims (15x6 Vintecs up front with 26"-28" Sportsman tire up front, your suggestions please)

You were right, you do have a lot of questions. I haven't installed one on a '79 F100, but I have seen them on older F100s. You might contact rcmotorsports7@mindspring.com to see if they have a cross memeber. I think you'll like the options the Mustang IFS will give your project.

Can you answer my other questions?

i'll try. if you order a mustang II IFS you can order any bolt pattern you want, and as for the adapter plates, i've seen them before in JC Whitteny before but thats all i know. as for the rim and tire size, when your tire hits the box it's too big .
