You only have one set of quad shock on your stang, which most people remove. When you do that, though, your stock U/L control arms aren't strong enough to prevent wheel hop b/c they're a stamped design. Aftermarket U/L's are usually tubular or boxed design and are a LOT stronger, so you can run them w/o the quads and not have wheel hop in most cases.

The lower arms locate the axle front to back and help control the pinion angle to the driveshaft/tranny. The uppers also located front to back to a certain extent, but are more for centering the rearend under the car. That's why you can get rid of the uppers when you go to a panhard bar and torque arm setup....they do a much better job of centering the axle and the uppers are no longer needed.

 

The stock arms are stamped and are not anything special under load, causing flex. Aftermarket arms are much stronger and better able to handle the weight transfer when launching or accelerating. I would say you will feel a diffenence; it won't be as sloppy when you get on it....

 

Maximum Motorsports told me that with a panhard bar/torque arm setup you dont have to run upper or lower control arms... Im not sure how thats possible because Im not exactally positive how a torque arm bolts up but thats what they told me......

 

You need lowers, too, from what I understand. It makes it a 3 link suspension instead of 4-link. The Tq Arm attaches to the tranny crossmember and then to the rear subframes and diff.

 

Hey Blue,

HERE is a link that shows the install of a MM panhard and tq arm. Note that he keeps the lowers, but removes the uppers.

After you said what they told you, I did a little looking to make sure I wasn't misinformed....

 

You could also get Steeda 5-Link, but i thought it was overkill for me so i got thier aluminum uppers and lowers, subframe connectors and adjustable rear swaybar..My rear end now is super tight around turns and from a dig...I also have sportlines and nw shocks that i put on last month.

 

yes,i have a set of granatellis and yes they work..
