    Has Anyone ever taken a spring over axle and moved the spring to the front ? it's a dropped speedway set up with 4 bar. Sure seems like it would work. Just wondering how to fab the perches and hangers. Any pics.

    Fords from 1935 onwards were built (using radius rods not 4 bar) that way from the factory.

    I prefer the spring behind the axle for appearance purposes.
    I'd call that the true suicide front end.

    Spring in front maybe OK on a fully fendered car IMHO...
    I've seen a kit available years back but do not recall who sold them.
    I believe it used some kind of adjusting bolt locking system against the front axle to prevent the batwings moving as if they were hinges as the spring flexed, which would obviously stressed the 4 bar joints beyond what they are designed for.

    yeah that's what I referring to. I'm thinking if I just mimic the spring behind setup I should be fine. I can buy the batwings through speedway. Thanks

    What kind of car? That will move the axle back a few inches. You might not be able to turn the wheels. It will change the whole look of the car. Prob not for the best.

    Right, that's exactly what I want. It's a 30 five window. I put a blown sbc in it and don't want to go back into the firewall anymore. So I moved the front crossmember forward 1 1/4 " to clear the lower pulley. I'm thinking this would get my wheelbase back close to where it belongs

    Here's a shot of my Model A with the spring in front. This setup dropped the front and rear of the car about 4 to 5" with nothing else done.

    Rear axle is a spring behind setup.

    I thought the "spring ahead" was referred to as "suicide" ?

    That Speedway 4-bar I'm using on my 40 pickup may be removed, in favor of a tradional split bones setup....The 4 bar, with spring ahead, puts a tension load on the upper bars, and a compression load on the lowers.......

    I'll know, after driving it a while this summer.
