    Hello all,

    I’ve been looking around like crazy to find an answer for this question. I’ve been told the percentage of up travel to drop or sag should be 50% either way. I wanted to know if I had the option to get an inch or two more droop vs up travel should I?

    I’m running leaf springs (56”), a shackle flip, and the 14.5 inch travel bilstein 5125’s inside some hoops mounted almost vertical outside the leaf springs. It’s a 1977 k20 and I want to do some crawling more than high speed stuff.

    I was thinking setting it up as 5” up (hit bump at about 4”), keep the leave from doing a “W”, and the rest down travel (8”). Of course I will sacrifice an inch or two due to running the progressive polyurethane bumps from daystar.

    Or on the opposite, have 6 inches down and the rest up? I have a lot of droop, but I can move the shock mount up or down a few inches as well.

    let me know if I’m on the right path here,
    -Daniel

    I posted some pics of the rear suspension that I have now.

    My tires will hit if I don't limit up travel a bit with bumps. This leaves me with a ton more droop than up travel. I see no problem with it set up that way. It is very common to have lots of droop vs up travel.

    I'm probably closer to 80% droop. I'm happy with it when going slow, tend to regularly find the bump stops at any speed, but it's anything but a go fast rig.

    Deceiving picture, but it was over 4.5 feet from driver front to passenger rear.

    Well it seems as if I want to be doing slow moving, more droop would be better. I definitely don’t want to be slamming the bumps if I’m going fast. I do like to do some hauling ass from time to time I think I’m going to shoot for the 60-70% droop area. For what I do that seems like it would be best.

    I’ll update you guys with pics and details of the build when I continue to work on it next week.

    thanks for the quick reply’s!

    Keep the shock from bottoming out just before the springs flatten. And use that as your stop point for the bump stop also.
