Your car will be slow if you don't get this right | Zach Builds a Sprint Car Ep 4

[@RyanPetrynka]

I've been a sprint car fan for 3+ decades. I've read many articles on sprint car suspension and every one of them confused me. This video finally helped me understand. Thank you so much! Many years of confusion finally gone!

[@ARyan-ln1db]

Another great video to the series. Appreciate the great info and taking the time to explain.

[@thomaskaech1022]

[@SuperBlockerB5]

Thanks so much !!!

Why didn’t you check the rear is square after you bolted and tightened everything?

[@SuPerTrapp87]

On the radius rod orientation, what is the reasoning for having the left-hand threads facing outwards on the left side of the car and inwards on the right? Does that help keep the jam nuts from loosening up? But then looking at the closeup when Zach put them on the car they were opposite what he said?

[@ChrisS3c]

Good eye! I noticed that after reading your comment.

[@jimrieder4600]

You’re correct, it’s so everything stays tight. You want it orientated so that if the tire rubs the radius rod, it tightens it up. The left rear tire is very close to the left side radius rod.

Apologies if this is a dumb question, but can every driver build a car from the ground up like this? BTW - great idea to do this video!

[@DIRTRACKR]

No sir. There are plenty of drivers who don't know much about the parts and pieces and how they work together.

[@Swingtools]

Sprints cars, specifically.

[@Swingtools]

@@DIRTRACKR Thanks!

[@420Jspec]

By "drive" are you referring to forward bite?

[@jimrieder4600]

Hanging the rear with ratchet straps helps get the setup blocks located…

Do u really have a sweet wing..!!??

[@RyanPetrynka]

My gf who's also a sprint car fan made an interesting comparison - is the Jacobs ladder equivalent to a shock absorber and the torsion bar equal to a spring? Another question - apologies if you explained this, but what does the radius rod do?

[@johnunruh1086]

Jacob ladder locates rear end left to right keep rear end centered so torque ball is free and not bound up. Radius rod located rear axle front to rear. Moving radius rod up and down changes rear steer in axle.

[@johnunruh1086]

Torsion bar is the spring

[@420Jspec]

Equivalent to a panhard bar in normal vehicles

[@bigdaddy-nc5hc]

dude get a true square

[@DobbsAutomotiveInspections]

No, Sorry, just chalk it up to me having a bad day.

[@DIRTRACKR]

Hope it gets better!

[@DobbsAutomotiveInspections]

At this rate the car will be ready 2025

[@DIRTRACKR]

Would you rather I just posted one 13 hour video?
