Im not really familiar with what they are for beside wheel hop. do they serve another purpose? Do they help keep the tires on the ground if you go over a bump. any thing else they are good for?

I may need to replace mine

They're just band-aids to compensate for the awful factory control arms without affecting NVH...


...unless your name is MFE, and then they are awesome!! :nice:

Exactly. The factory 4-link rear had rubber bushings which allowed for deflection while turning (attempted to prevent suspension bind) and this deflection can results in nasty wheel hop. The quad shocks were installed to minimize the potential for wheel hop.

:lol: :rlaugh:

I installed MM LCA's w/ the poly bushing on the body side and the spherical bushing on the diff side and FRPP UCA's. I removed my quad shocks and I don't have any issues with wheel hop, but that's just me.

Same exact setup here.

Without the quad shocks...I had wheel hop. I put them back on and it was gone
 
There are likely a lot of factors that contribute to it... I mean I only make 237 RWHP, and 281 RWTQ so perhaps if my car made more power I would have wheel hop issues :shrug:
 

I was asking are they used for any other purpose BESIDES wheel hop. I didnt ask if I need them or not lol Hense why i said I may need to REPLACE mine

I dont race and dont do burn outs....often :P

I didnt know if they help keep your wheels on the ground when going over a bump ect.

so instead of copying and pasting a link that has NOTHING to do with what I asked.. you should read my post again

so ill say it again. Do they serve a purpose besides controlling wheel hop. are they there for any other reason?
 
The point is this topic has been beaten to death on the forum. The general consensus is that the quad shocks do nothing except prevent wheel hop and it is debatable whether or not they are needed to mitigate wheel hop if you have aftermarket control arms.

I figured it was pretty clear that they serve no purpose other than preventing wheel hop and provided you with a link to a discussion forum so you could decide for yourself if you want to keep them or get rid of them.

Had they served another purpose aside from preventing wheel hop, don't you think people would have included that in the debates about their usefulness?

Or unless you're any of the following people, or the others just like them who never posted, and you're not a forum shill selling knock-off watches out of a trenchcoat.

I was a victim of the no quad shock/ aftermarket control arm wheel hop fiasco... I wouldnt reccomend removing them.

I already have Megabite UCA and LCA. Don't know why I still have wheel hop, trying to figure it out...

[later]...Well, I put the factory original quads back on and fixed the problem. Haven't been to the track but no wheel hop yet.

Thanks for the input everyone.

I have Mega Bite Jr. Lowers and without the quad shocks have alot of wheel hop. Put the shocks back on and no wheel hop at all.

unless there is an elimination of the factory uppers due to the addition of a torque arm or panhard bar the quads should stay. i was one of the victims of the internet myth that when aftermarket control arms are added the quads should go.

I was one of these people that bought into the internet hype of not needing quads once I got control arms.

On my 87GT, I installed Megabite Jr's lowers with FMS uppers and I got wheel hop after I removed the quads. Sometime later I picked up some BBK uppers and lowers and also got wheel hop without the quads. BAD wheel hop at that. I installed the quads and it improved.

I've got Steeda uppers & lowers. But I still get some fishtailing when I drive irresponsibly--HA, so I just bought a set of Gabriel quads to replace my well-worn (108K miles) stockers---they DO make a difference.

My 88 GT had Steeda Aluminum LCA's, stock uppers and wheelhopped bad enough to break one of the parking lights without quads, with quads it was smooth.

I had baad wheelhop with FRPP HD uppers/no quads. Put in quads, and the wheel hop was gone.

I had really bad wheelhop just in street driving. I replaced control arms and the wheel hop stayed the same. I replaced my quads with Koni ones that I found on E-bay cheap and the wheel hop went away. Traction got much better too. New Quads were a great improvement on my car.

I have always heard toss them when you get "real" control arms. I spent close to $100 to go to a track rental this spring, and I almost took the quads with me just in case...The track was good, but my car was wheel hopping bad in 1st and 2nd. So be careful with that conventional "wisdom" that they aren't needed once you change out your stock control arms... My car wheel hops like a bitch without them.

OK a buddy was driving my car the other day and he started doing a burnout and the car was wheel hopping a little bit.
I have UPR Double Adj. uppers, Jegs Lift Bars, 03 GT rear springs and 50/50 Lakewoods...Also long gone are the quads....Why am I having wheelhop?

Glad I'm not the only one [who got wheelhop without the quads]. I have Granatelli/JD's performance arms and I had terrible wheel hop last time at the strip. 60' was 1.81 when I had the quad shocks, dropped to 2.05+ with them off.

I removed my quads when I replaced 6 of the 8 bushings in the rear with poly bushings and had to reinstall them because of the wheelhop. :(

I noticed that when i installed a set of steeda upper and lowers I experiened alot of wheel hop after removing my quads.

I just installed some lower control arms, and they didnt help at all! I still have wheel hop....

...its a 88 LX i put on JD's performance control arms. I have always heard that you leave the quad shocks off when putting on lower control arms...

[later]...put the quad shocks back on and tightened up all of the bolts, my wheel hop is almost gone...It's interesting how after putting on the quads with the new Control arms, my tires actualy squeal instead of just jump.
Pretty exciting :)

[later still] Lemme just say thanks again to MFE, and all of the other guys who gave me advice to stop the wheel hop. Its totaly gone now. All it took was 5 minutes bolting my quads back on and the wheel hop started fading fast. I think as the parts are wearing in its getting even better. At first I had a little bit of hop, but I took it out today and I couldnt get it to hop at all. Thanks again guys.

just an update...

I replaced the quad shocks with the Gabriel #14039's that MFE recommended and the wheel hop has been eliminated! The old quads were in terrible shape, and I'm glad I've replaced them. I'm accelerating much smoother now with no hiccups whatsoever.
 
Like already stated the quad shocks are there to control wheel hop and to absorb the swisting action of the axle housing. quads came in full production on '85 and up stangs and started showing up on the '84 SVO and some early '84 mustangs. Pre quad days Ford used a traction bar type set up to control axle hop. I swapped over to police rear uppers and maximum motorsports lowers, '01 bullitt springs, etc and had to put the quads back in. some can get away without I couldn't and from reading other posts not alot have. If you want factory quads ( they are skinny and the body is smaller than aftermarket w/o the need to cut the dust cover) you can still get them just order them for a 2004 stang, they used the same quad up to '04.
 
I was never gonna get rid of them. I figure if they are on the car they are on there for a reason. I was trying to find out if they were on there for any other reason besides wheel hop. cause mine are stock and im pretty sure my car has 190,000 miles plus on the car.

My back end seems to bounce off the ground a lot over bumps and twists a little when the car shifts. just trying to find out if new quads could fix the problem.

I already have newer shocks and struts in the front and back

Your rear "bounces" because its a solid rear axle. The quad shocks will not help the twisting. Your bushings are moving around and thats why your car is sloppy when you apply torque to the rear end.

Next time you are under the car, take a small pry bar or a large screw driver and lift up on the rear control arm where it connects to the rear axle. Yo will be suprised at how little force it takes to move them. The factory rubber bushings are very soft and made to give a nice ride, thats about all they are good for.
 
Well, after reading this post on and off again for the past week, I decided to throw my quads back on and see if they made a difference in my launching on street tires....Nope! But I did end up doing some huge burnouts and a few doughnuts in an abandoned parking lot about 1:00am this morning :) So it was worth the "test run"!
