4 link rear ends

Do I still need to run a sway bar with a 4 link rear?

I don't know what it's called, but you do need to run a bar diagonally to control side to side movement.

GT....... Your thinking of either a diagonal link or a panhard bar. Both of those eliminate lateral movement of the axle. You can run a sway bar if you want to stiffen up the car a little too. A sway bar will help decress the body roll and weight transfer.

Thanks Tony, but would a sway bar be totally different from a panhard/diagonal bar? I just want to know. Thanks again.

a rear sway bar may help to reduce wheel hop under hard acceleration.

A 4link will eliminate wheelhop. an antisway bar will NOT affect wheelhop and does NOT stop lateral movement, the only thing it will do is reduce body roll and weight transfer and also make your ride stiffer. What you need with a 4link is a diagonal link or panhard bar like tony said.

On 4 link equipped race cars they use anti roll bars to control body roll. Hope this helps.

GT........ like they mentioned above, A sway bar will only reduce body roll. It will hardley effect wheel hop at all. Sway bars are completely different animals from panhard bars, diagonal links, watts link ect.......

Ok tony, since they are totally different, where do you mount the sway bar on a 4-Link? Sorry for all the questions, but this is place to ask!!

No problem man......... The most common sway bars will have an attachment on both sides of the framerail and two attachment points on the axle tubes. Now Chris Alstons Chassiworks makes a *****in torsional sway bar.......

Tony.....

Me:.........I only need a 17" v belt

PCG:........( frustrated like Im the idiot ) What year is it Sir

Me: ( thinking to myself, Ok I'll play ) Its a 1983 Chevrolet K-10

PCG:........Is it a 4 wheel drive?

Me:....... I think thats what the K stands for but Im not sure

PCG:....... Now what part are you looking for ?

Me:........ Alternator belt

PCG:...... Does it have a 5.0 or a 5.7 liter motor ?

Me:........neither

PCG:....... It dosnt have a motor in it ?

Me:....... Yes it does.

PCG:....... Well its either a 5.0 or a 5.7...

Me:........ It is a 7.4L

PCG;....... It cant be...!?!!

Me....... May I borrow a tape measure........

You do not need a sway bar with a four link. Sway bars are for road cars, and 4 link for drag cars. It is a conflict of interest so to speak. The four link by design will control body roll very well. This will be more true the further you place the front bar holes. In high HP(like 800 and up) you might need a torsion bar to control body roll on launch, but for a weeked worrior that sees some track and street time, you dont have to worry about it.

Well, Actually, Its going to be my daily driver, I think the 4-link is better than latter bars, And I'm fabing a new frame anyway. we're talking a street truck, 2600 gross pound vehicle with at least 500 horsepower. with a redline of about 7grand. All wheel drive.

I hope you have devised a way to keep the rod ends from wearing out. The urethane ends suck, and the solid ends will not last long on a daily driver. Not do be a *****, but it is something to think about. Most 4 links are not designed for everday wear and tear and will not last at all.
