hello all, so I'm putting a 9" in my 65 fastback, and I'm throwing a ton of parts at it. Detroit TrueTrac, Moser 31 spine axles, factory ford 3.50 gears, and wilwood disc brakes. Before when I had the open diff 8" rear end, I would get terrible wheel hop when I'd dump the clutch or slam gears and I would like to get rid of it completely. I have been looking into putting the Grab-a-Trak Shelby style traction bars on, but my dad talked to the guys at Maier racing at the goodguys show the other day and they said that the shelby style trac bars will help but will not eliminate it all. If any of you out there have had this problem and fixed it or know how I should, please let me know! It would be a huge help!! Thank you
Ford's solution (sort of) was to stagger the rear shocks. One shock was mounted in front of the rear axle, while the other was mounted aft. I believe that this was done with a unique upper shock mount cavity and possibly different shock spring plates, also. You would most likely have to find a donor car to make the fix, most probably a 69-73 model. A bit of complexity, true, but not so much as ladder bars. How about old style traction masters?
I went with Maier Racing springs (poly bushings in the front) and their Bilstein shocks and it cured my wheel hop 100%, and gives a great ride and handling. It also hooked up well with Nitto 555R drag radials. Maier Racing knows their stuff (they race it). It's a $600 solution (with shipping), but if you need new springs anyway (I did) it's not that bad, and the ride is great.

This is a question of extremes in order to find the limits of under riders. How extreme is your car?
With a 5 leaf setup and a simple set of under rider traction bars my 400 RWHP 65 has never had wheel hop through an AOD. I did however blow the driver side bushing out at the drag strip after running an 11.8 on 275 drag radials (took 4 years and many passes before the bushing blew out).
Back in the day a $30.00 set of traction bars did the job but looked good too
Wife,........."You drove how far for that thing?"
Daughter,..."Theres no inside and it stinks."
Friend,......."Dude, thats a rusted piece of sheet."
Son,.........."This old car is cool."
4 1/2 leaf mid eye springs on my 66. I used to have the under rides till I saw the bushings were falling apart. Took them off and now just have the springs, panhard bar and Koni reds. Never have had any wheel hop with either setup. Now before I resto modded the car, it would hop bad with the old springs and a Lakewood type traction bar.
Your getting many different answers because there are many different causes..You need to find the cause to find the cure..Some things that will cause it for sure are worn spring bushings,weak leaf springs,worn out shock absorbers to name a few..If it is simply the springs wrapping up you can cure it pretty easily with some sort of slapper bar or try clamping the front half of the leaf spring..I am not a fan of the shelby bars..My brother is running them and still has some wheel hop issues that we are trying to sort out..I am running a simple bolt on style slapper bar which works well but I will be getting some caltracs when the budget allows..
