    Pics of rear suspensions

    Right now I'm building my narrowed rear frame rails. Soon I'll be building my rear suspension and was hoping you guys could add pics of what you are using. Plus any pics of other cars for references. I'm debating solid long traction bars, ladder bars, or??? It'll be coil springs and seperate shocks (not coil overs). Thanks for any pics that you can share. Mark L
    It's not a period gasser but it is what I would have built had I been of age to back then.

    Yesterday I was so far behind that the guy in front of me was me!

    Here are a few, they are different shock locations or fram rail shapes to give you other options, hope it helps.

    Hey guys, any pics of your gasser rear suspensions, or any from other sources? I'd sure like to see how they were done back in the day, just for reference. Been trying to get in my head how I could make a long ladder bar type traditonal old school ladder bar suspension but still retain some suspension articulation for bumps and driveways etc. Without the stiffness of locked up ladders. I was thinking of building a long, straight four link suspension, with parallel bars. The bottom bar looking like a traditonal girder ladder bar but the top links would be bars up out of sight of the same length. It would give the look and the lift of a single ladder bar but the articulation of a four link. ?? Any thought from you guys on my idea? It would still need either a panhard, a watts, or a cross link for side stability. Possibly using a Johnson Joint at the front mount points. Or could that leave it too loose? Remember this is for a street strip car. Steve, any thoughts? Mark L

    Hey Dave. Not sure if you're asking about the stock suspension or my modified suspension? Factory is a GM four link with coils. I'm building a narrowed frame rail and ladder bars using the original spring configuration probably using some station wagon springs for some stiffness. Then seperate shocks. Mark L

    LONG ladder bars, and rock crawler joints at the front end of the ladders. Ditch the coil spring idea and run coilovers with heim ends. Triangulate your ladders and use a wishbone locater bar. Should give plenty of articulation.

    I don't like to use the springs as a tuning aid.... I use the correct spring to support the car, then tighten or loosen up the movement with the shocks... Stiffer springs in the rear can be a detriment to weight transfer..... One other thing we used to play with on coil spring rear cars was to run the regular drag shocks on the rear, then add an air shock on the right side, forward side of the housing to use to preload the right side a tad....

    I'll start out with the original cars springs and go to station wagon springs if I need stiffer. Mark L

    I went with Comp Engineering ladder bars and coilover shocks with a panhard bar. I don't have a ton of miles on it yet, but so far it handles really nice. No wheel hop, and even decent cornering for a gasser. Really smooth down the freeway at 70 mph too.
