We didn't get it in the video, but it gets pretty violent. Will shocks fix this, or is it an issue with the springs?
The tires are Kenda motorcycle tires with 12 lbs pressure.

Are they balanced?

That, my friend, is a good question. I guess I should start there. It doesn't bounce until I hit a hole or bump though, and comes out of it eventually. |

I'd put some shocks on first and go from there. Didn't see any shock in the video. _________________ HBB took me to BBV. |

No shocks. The frame has a mount, but the lower control arm does not. I thought about welding a mount to the control arm, but they are polished chrome. |

You must have shocks on it to stop it while driving on the street. If you were just duning then you would get away with it. Same as getting a wobble from not having a steering dampner. |

Yep, just the left. Will take it apart.
Thanks. |

Grind that gaudy chrome off and weld a shock mount on. Function before shiny shit I always say. _________________ HBB took me to BBV. |

agree, 110%
A cheap way to add a mount is to weld on a 12mm rod coupler. Just grind off the zinc before welding, and make sure your shocks reach with .75" extra extension...

Side note: When you get that shock mount welded on I would put some regular oil filled stock shocks on that rail. I'm thinking a gas filled may be to stiff for that front end. _________________ HBB took me to BBV. |

What tire pressure are you using in the front tires?
As light as the buggy, anything more than 12PSI (and that high IMOP) is to much. _________________ Joseph

I agree, but I hate to have to remove chrome from 4 trailing arms. Guess I could just paint them all.

My trailing arms have no remnant of an old shock mount whatsoever, so I'll have to do some creating gusseting.

They were at 12 psi in the video. |

Only need to grind two trailing arms because only the bottom ones get the mount. Creative gusseting is pretty easy with some scrap 1/4" plate. What Requires a bit more precision is getting the mounts parallel. A straight edge is your friend. _________________ 1800 Type 4 Berrien 295

I'm thinking about taking the torsion plates out and going with a thru rod and coil-overs. What shock would you all recommend in that case? |

Gas is way way too stiff but to you know how hard it is to find oil filler shocked these days?
What I discovered by accident when my front end build went a different direction is that the commonly used air shock only really has rebound damping. Compression is just the rubber and air pressure. This makes them darn near perfect for a light buggy where you want the suspension to compress but need enough dampening to prevent the OP's problem.
I run like 40psi in them which is just enough to firm the bladder up. |

I almost did this but shied away for two reasons
That 12mm stud isn't designed to carry the weight of the suspension
If you lose a shock the front is going to plow the ground and will be in for a wild ride!
So what I did was I split the difference. I removed the center block from my upper tube, that turned the upper spring pack into a sway bar and removing it from the spring rate overall but allows it to retain the arms. Like a thru rod.
With that done it was a little soft so a pair of air shocks makes up that difference with just a little air. Gas charged shocks were actually too stiff
It rides like a dream now AND handles like it's on rails |

I would say that going coil overs is a lot of work just to fix that problem. You could swap a pair of stock arms on there and bolt your kyb gr2 on. I all but guarantee it keeps that wheel hop in check. _________________ HBB took me to BBV. |
