what about a shock absorver instead a pinion snubber ?

[Nacho-RT74]

yes, I have been thinking of that, somekind of small shock absorver, slow compression-fast release action. Small room for that kind of assembly but I think doable by some manufacturer.

Thinking mostly on street/strip cars regulary used on streets

It wouldn't be too hard to fab it up yourself with something like this, it's only 6" long, who knows what stiffness would be appropriate though:

the problem is unlike caltracs or a rubber snubber, you would be tying the third member directly to the floor pan--seems like that could do strange/unpleasant things to rear suspension travel and behavior.

ma mopar got plenty of things right back in the day, and that's why a good ol rubber snubber does the trick just fine while chevy and ford guys need slapper bars. Be proud of the elegant simplicity

It would still compress and change pinion angle. Driving on the street isn't a big issue for your pinion angle to change a bit, but on the track it would compress and change P-angle and still leave time at the starting line.

Just my .02

I think one of the suspension companies out there already offers a "traction shock" set up of some sort. I forget who, but I remember seeing them advertised in the mopar mags.

yes that my goal... street use, being less strees to the joint... Pinion snubber could hit constantly againts the provision underneath the floor and maybe making it anoying

thats what I though, maybe made by myself, just looking for the best piece to make it.

and maybe using ball joints to affect less as posible the regular sway movement

Looking at the mountain bike shock idea... they also use rear air shocks that "lock" in place for climbing hills (keeps the bike from bouncing which robs power needed for moving forward). For the street, it would be nice to flip a switch/pull a lever to instantly lock out the upward travel of the rear end. Not sure how much pressure you'd need to hold though.

On the street you really don't want the snubber hitting. Only at the track for traction and to keep your pinion from torquing into a positive angle. 

For something in an easy adjustable snubber I would think fine threaded and turned up and down by an electric motor.

The Ford Mustang 5.0 had what were called "Quad Shocks" on each side of the rearend to help control axle windup..did they work? Never knew, as the FIRST thing everybody did was remove 'em in favor of larger rear tires.

I think it was Mopar Action & the install was on the green brick about....10 years ago?

[HPP]

No, it was just in the last year or two. I think it was Just Suspension and they called it the Ground Pounder kit. However, they don't show any such thing on their web site. I'll have to see if I can dig up an old mag and verify. Maybe they quite making them for lack of sales or usability problems. Dunno.

Rick gave Just Suspension a heads up on the 10 year old setup on the Green Brick which they marketed as the Grounder Pounder.    I couldn't find it online after they redesigned the website. 
Rick was putting the same kinda setup on the Dakota.
