I know this is an old video but I've watched a whole bunch of these from you and it's been incredibly helpful. I'm building a chassis for a Buick Grand National drag car on my channel and I owe a lot of the knowledge to you. So many little details and tweaks that are helping me build a well designed (I think) and consistent chassis. Thank you very much for taking the time to share all this info.

Well explained, especially from a fabrication point of view.

I have a question, on my truck we installed a 4 link (your videos are a huge help) and was unaware I needed a ARB. First trip out way too much body roll,so I installed a ARB and now the truck has this wobble upon shutdown. The cab sways from side to side and the steering wheel will saw as its swaying. If you don't try to stop it itll get violent, and try to turn truck sideways. We've been fighting this for 3 weeks now. Competition engineering 4 link,diagonal link, viking double adj coilovers,and a home made ARB from moley tubing. Any pointers to why it could be doing this?

It does not look like the rear end is hanging when you set the anti-roll bar,But I maybe wrong.

Great video series. Quick question, I’ve always been under the impression that then sway bar end links should have no preload when the car is settled on the ground. Is this scenario different since it’s a true race car?( My application is on a road car/track car build).

[@dons1932]

You misunderstood him. The 4 link arms are preloaded, the sway bar is neutral. He then goes on to say for ease of maintenance it is all done as one, with tyres off, though some people try to set the sway bar on the ground - which is no biggy - but you don't set preload to the arms that way as it will be different. Which as just mentioned - why it is all done with no wheels and tyres bolted on.

I understand the concept, however if you are on a track that has oscillating dips then the car will dance dangerously down the track.
