Are traction bars ever right on a Mopar??

Well, the pinion snubber (Adj. unit) was intended for non weeinie sure grip equipped cars for the drag strip w/ S/S springs. It works very well for that application. (FWIW, I’m NOT making fun of your car(s).)

The tractions bars are fine. Many don’t like the idea of the snubbed portion contacting the spring. Not all traction are are the same length and most are short on where they should land the rubber snubber, right under the front spring eye. This has people thinking (true Or falsely IDK myself) that it will bend the front of the spring. (Mad power needed for that I think)

I am also not so fond of the way they attach to the spring.

Your test is inconclusive and I’d like to see the street tires on the 360 Duster and how that works and performs.
