    Parallel Leaf vs. 4-link

     



    I am about to start the chassis build on a '37 Chevy coupe.

    I have not used a 4- link suspension before and am needing the pros/cons between the parallel leaf and the 4-link.

    This will be a street rod with a 383/700R4 combo.

    Any info will help - Thanks

    Do you mean a 4 link with coilovers??? IMO a triangulated 4 link with coilovers and polyurethen rod ends (not heim joints) is probably the best rear suspension on the market for a street rod. The triangulated 4 link by it's design does not require a Watt's Linkage or Panhard bar and doesn't have the tendancy to bind as does a parallel (even or uneven bar) 4 link. A leaf spring set up is the easiest suspension to set up, and also the least tuneable of any...

    daves right. triangulated 4 link with coilovers or bags is probaly the best setup
    and hes also right about heim joints. they suck

    This ride will be 90% cruising and 10% playing agianst friends in a little 1/4mile joust. This won't be a race car, but I would like the best performance that my shallow pockets can afford.
    I was thinking the triangulated 4-link with coil-over shocks. I do not want to deal with pumps,lines and compressors that come with bags.

    It sounds like the 4-link might be the way to go over leaf springs.....

    Thank you all for the info, found a site that deals in polyurethen rod ends and am going to lean in that direction.

    Besides working better It also "looks" better,compared to boring old leaf springs IMO.
