Universal Traction Bars install on a Duster....

Just look at where the tire technology is at. These drag radials are something else, along with track prep.

I'm just say'n, if they had my tires on their Dusters, there'd be no 10's or anything else close...… and to try to get close they'd be look'n for some sort of traction-aiding device.... LOL
(probably watch my video again and go to wrenching) ….. :D

I had a snubber on every mopar I owned until I bought my Calverts. The video above was with 002 003 springs and a snubber. The tires were 4 to 5 year old DOT tires. The car weighed 3650 with driver.

But you are correct about track prep on the street the car was a hand full.
I bought a 69 Coronet R/T 4sp Dana in 1973. It had Lakewood bars with adjustable J bolts to load the spring.
I torched them right off. I already had a 69 RT without them both cars were dana 410 trac-pack cars. I felt the difference and preferred no bars. The bars made the car ride like a brick. Every car I buy with them on now I put the rectangle bar on the steel pile for fab work. I didn't know you all would even think of buying them.

Here is the traction system we are going to use on our new lighter car. The wheelie bar triangulation forces the tires into the street. We want to keep the car leaf springs with a 29 x 10.5 small tire class. We'll see how it works
