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!!![]()

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.

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.
Do they serve a purpose besides controlling wheel hop. are they there for any other reason?
so ill say it again. Do they serve a purpose besides controlling wheel hop. are they there for any other reason?
Or unless .... you're not a forum shill selling knock-off watches out of a trenchcoat.


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.
That right there, THAT'S funny!
