Wheel Hop

-
slapper bars should not be used on Mopars. They are not designed like Chevys. Behind the eye can bend the leaf spring.
That's why they aren't installed behind the eye. They install under the eye. Traction bars have no clue as to what car they are on. They will work good with any leaf spring suspension.

Now, all that said, IMO in this case, while they would most likely get rid of your problem, I believe they would be a band aid. Normally, wheel hop is associated "somehow" with leaf springs. Are you certain they were torqued properly when installed? 45LBFT is the proper torque with the final torque with the weight on the wheels.

Correct. The pre-historic Cal-trac. And I know, the axle sits forward on the leafs n mopars. I've been told for so many years they don't work on Mopars that I've just learned to smile and say ok. :)
 
Not sure in torque but I can check.
What I would do is just break the u bolt nuts loose with the weight on the wheels. Not REAL loose, as the housing is above the springs. Just loose. Then retorque them to 45LBFT. If they are too tight, it can affect the pinion angle and have the springs in a bind. Both of which can contribute significantly to wheel hop.

They work very well if set up right. They are in the plans for Vixen when she gets taller tires.

yep beßt to avoid an argument. Most people don't know how to install them.
 
I have a 1974 Duster, With Calvert Cal track bars with their split mono Leaf springs and nine way rear adjustable shocks, no wheel hop.
 
The 1"1/2 change in tire diameter will change the geometry of the suspension.
 
Back in the day Direct Connection and Mopar Performance offered leaf spring clamps that you would put at the front of your leaf springs, I have some but packed away so I can’t show a picture...but they could be easily made....supposed to help eliminate axle windup and wheel hop....Dick Landy also talked about this during his drag clinics and in books...I found these 2’pictures doing a search on FABO

i had the same setup on my 73 340 duster,no wheel hop. clamps were homemade and adjustable snubber
 
If you try running one, maybe about where it's almost touching with you sitting in the car...itll put it all on the tires...
When I clamped the front of my leafs on the 68 Coronet, and threw on the snubber, it tightened it up pretty darn good. I was in my 20s we ran that car on the bridge, and out at Harney in the early 90s. Mickey ,Sportsman "I"s many a " high rpm" clutch dump...
 
Yup even the MP suspension book talks about clamping the front segment and unclamping the rear segment. Of the two, traction bars or a snubber, if you just GOTTA run one or the other, I prefer traction bars. I don't care if "they ain't Mopar" or not, it's easier to adjust each side independently, as one side always acts a little different.

Learning a lot here!

Yessir, torque lifts drivers side, rolls to passenger side.

Of the BODY, yes. It's the exact opposite with the tires. This is why an open differential will smoke just the right rear. The action of the suspension takes weight off the right rear tire, giving it less traction. The body does the opposite.

100% agree... a video i made on the subject

Dig that, I'm Assuming that's why our cars actually " lift" , or appear to in in the rear? Due to the torsion bars?

No. That due to axle wrap. As the car accelerates, the pinion gear tries to climb the ring gear. Since it cannot, the axle housing rotates the opposite direction of the drive axles causing the leaf springs to push UP on the car while pushing DOWN on the housing ans tires, planting the tires into the pavement. This is much more pronounced in cars with race bred rear suspensions like with SS springs or Cal Tracs. You can really see the body lift during a hard launch. The Mopar leaf spring rear suspension is about the best there is at taking advantage of this, IMO.
