Suspension Quad shocks

AeroCoupe · Aug 21, 2026

Meh I am going to disagree. I haven't had quad shocks on either of my Foxes for 20+ years but I do have quality UCS's, LCA's, and shocks. From summer tires to all season tires and to drag radials no wheel hop.

I had to put them back on mine. MM lowers, new OE style uppers, bilstiens, PHB, still had the hippity hop. Checked pinion angle. Just put them back and problem solved.

Your o.e.m. uppers are the weak link, cause I've been side stepping my clutch for years without any hop, I've got metco adjustable uppers and lower arms with greasable bushings.

It’s what MM recommended to me. They aren’t original they are new, along with new axle bushings. All low mileage stuff. In fact there have been two different sets of them each at this point. At this point I’ll live with the quads and just pull them when I finally install a torque arm.

Side stepping clutch sounds like you run slicks, unless you just like smoke showing.

ALL I CAN SAY IS QUALITY UPPER AND LOWER CONTROL ARMS WILL HOP ON RADIALS(HIGH 12 SECOND CAR) WITH T5 AT 3300LBS WITHOUT QUAD SHOCKS.

BEEN DOING THIS SINCE THA EARLY 90S.

THE OLD SCHOOL Southside Machine control arms(new ones arent the same) or Lakewood traction bars ARE DIFFERENT. THEY WILL KILL THE HOP.

Let’s just say that in your experience this happens as it is not my experience nor is it for other members here. Seems to be a case by case basis. Seems like most cannot get wide tires to fit without punting the quads but I’m sure some have made them fit. Regardless there are plenty of cars out there without the quads and no wheel hop.

What uppers are you using? What bearings/bushings are at each end? Are also running a set of battle boxes? Welded or bolted?

Qtrhrse23 · Aug 22, 2026

Tubular lowers poly bushings, uppers with poly bushings. NON adjustable. No battle boxes, I DONT LAUNCH this Fox like I did my previous. But suspension is the same. No front sway, Saleen tubular lowers, uppers with poly bushings, and Airbag if left rear spring. My 93 GT had thousands of launchs on it, same suspension(a 12 second bolton car they do/did exist) BUT with 3.73s. 1.67s ALL DAY ON ET STREETS. 1.87S ALL DAY ON BFG NON DRAG RADIALS.

NICE TO see you speak for EVERYONE ON THIS FORUM. Im NOT GONNA HAVE A PISSING WAR with you. If they dont STOP THE HOP, WHY ARE THEY THERE? Seems like EVERY Foxbody owner would of trashed them. Thats WHAT WE DO WITH DEAD WEIGHT. It must be a MYSTERY AS TO WHY 90%+ Foxes still have them. % goes up if a wide tire isnt there(like you mentioned). Lord knows they do nothing for cornering. Im out of this thread. Good luck.

Those are 50/50 shocks like post 2 says
The rear sway bars did as much for wheel hop as the shocks did
Used to break those sway bars racing them
That rear sway bar acted as the actual traction bar, and the 2nd set of shocks were the damper
Those were the funnest ones to drive IMO

TOOLOW91 · Aug 22, 2026

No quad shocks , solid spherical uppers , poly lowers

Zero wheel hop on a drag radial

Car makes enough to run 9.50s on the street pump gas tune to gauge horsepower.

AeroCoupe · Aug 22, 2026

Never said I was speaking for everyone. My exact words were “ not my experience nor is it for other members here”. Key word there is other not all.

It’s no pissing match so ease up. I was just stating my experiences with both my cars and you are stating your experiences with yours. Nothing more to it.

They are not the only solution to wheel hop, is the point.

Bullitt347 · Aug 22, 2026

I used to own a Mustang specialty shop. From 1994-2002.
Worked on and modified a ton of Foxbody Mustangs, SN 95's and SN 97's, Basically any Mustang up through 2002.
We removed the quad shocks on every Mustang that got upgraded rear suspension components.
Everything from street/street strip, DD's and Drag Only cars.
Not once did any customer come back complaining of wheel hop.
But that is just my experience. I am sure other people with stock/stockish rear suspension systems had a different result than I did.

Bet he's still here.

It was pretty obvious on my car the wheel hop was the lack of quads.
Motorsport uppers and steeda HD lowers and then MM HD lowers. Removed, wheel hop. Installed no wheel hop.

I don't remember if it did it when i went to double adjustable uppers with Heim joints at the body side, but i hated those so much i removed them fairly quickly.
I don't think my southside bars wheel hopped (and I believe they absolutely get you the best traction), too bad the damage they do is second to none when it comes to torque boxes.

Regardless, MM suggests motorsport uppers. So if that is the cause and it wheel hops, I really don't see the harm in just putting them back on.
I do not feel like just upgraded lowers solves it.
Besides, they are like $30 a set at rockauto.

oh boy. We should have a thread on the rear differential dogbone and it's purpose.
