    Anyone running spring under on a "hardcore" rig?

    After seeing Fred do a few rigs spring under that seem to work well, I've been curious about trying it. I have a little Sami on 32s that I put back to spua when I got it, but that's not what I'm curious about.

    I'm curious if anyone is running it on shit with big tires and gets wheeled?

    Obvious downside is clearance, not just directly under the axle but the mounts on each end need to be that much lower to achieve the same ride height. I made some high clearance spring plates to help as much as possible.

    Biggest upside is axle wrap, I'm hoping it will be minimal and I won't have to run a wrap bar.

    Rig is a 99 suzuki vitara (sidekick/tracker) getting 60s and 42s. I got some hand me down 4" trail gear toyota rear leafs, which have some decent arch, so I figured why not spua it to keep it low.

    Lots of desert rigs run spring under.

    On something as small as a sami you could probably run 57" Ford springs with the long end forward and get decent geometry.

      Buddy ran f150s on a Toyota, some kinda monster truck springs, sprung under. They worked great, other than he half assed the build and left the leaf bolts pointed down.

        There was a guy on the old forums that competed in a SUA Zuk. Dutch guy I think. Worked great. My best year bar none of wheeling was a stock(ish) Samurai on 32s with gears and a locker. I beat the ever living shit out of it, and never broke a single part.

          I don’t know know about hardcore, but I set up my s10 sua with a waggy 44. Old pic, some things have changed.

            go to a 44" tire and youll have the same ground clearance

              Dude, 47" YJ's are tough to fit under a Sami, 57s would probably be touching each other.

              I'm mocking up with 42 mtr/k's which are a true 42" so probably 2" taller than a 44 tsl

                Everything Fred and Dave have is spring under except the Cummins Tug truck. It has an antiwrap bar. Fred hates SOA because of axlewrap from big tires.

                Anymore only the old builds of my friends have SOA.

                  I never thought my 4runner had *that* bad of axle wrap, with good aftermarket springs. I wasn't doing a ton of climbing though.

                  I am kinda excited to see how this works really. I was going to do a triangulated 4 link rear, but I got these springs and some nice 2x14 resi foxes for cheap, so why not. I like leafs. Won't need a sway bar, and should carry all my junk better when its loaded down for a few day trip.

                    Fwiw Clampy has almost zero sprung weight in back and has 6” lift 63’s in back iirc. It flexes well enough for fred to destroy it every couple of years.

                        Huh, I really thought they were Deaver or similar from when it had the total chaos stuff in the front.

                        What's he destroy?

                        Those are ruffstuff?!? I looked all over for actual spua plate with no luck.

                          On his last trip to Oregon wheeling with the sketchy boys out of bend he broke the crank or something ridiculous on the 3RZ. Marlin just put a new motor in it. I asked him to confirm.

                          dave used those spring under plates in his mazda build.

                              X2 on the ruffstuff sping under plates. I am running alcan leafs with orbit eyes spring under in the rear of my 84 toyota pickup.
