NO spin and when it hits second it flat sticks.
Before with the 3.73 rear gears and no leaf spring tweaking it wheel hopped a tiny bit like chattering the tires.
Hit second gear and feel chattering and slipping of the tires.

The fix was an old school Mopar fix with a slight tweak I added to it.

Clamped leaf springs.
I put 2 clamps on the front 1/2 of the leaf spring pack (in front of the axle).
My tweak was add another leaf spring on top of the main leaf just a 22.5" long one that lays flat on top of the front 1/2 of the leaf spring pack.

No need to remove any shackles or u blots and no need to flip springs around.
I have done that on a friends Sonoma that wheel hopped really bad.

I also ran clamps on a Harley Davidson F150 supercharged truck that wheel hopped and fixed it.

Notice in the video the front of the truck body raises just a couple inches and the rear fender above the tire comes up an inch or so on the launch.

This effectively pushes down on the axle.

If your vehicle body is squatting in the rear it is actually trying to raise the axle.

I wish it was cooler and lower density altitude but it is what it is.
80.7° 76% Humidity and 3427 Density Altitude.

Higher stall converter on order and then more testing.
4,085 race weight with 6.0 LS bored to 6.2 and 4L80E with 2800-3000 stall circle D.
Stock 317 heads and 625+ lift cam.
Hopefully this thing will get int he 12's soon.
13.206 @ 104.01 on that run.
