Watts link.

Came across this video the other day. Pretty simple and straight forward.

Has anyone used a Watt's link setup?

I've been think about some different options for my rear suspension. One thing about 4 link and panhard setups that drives me nuts is the side shift when you hit a bump.

With that said, seems like a Watts link is the way to go.

I had forgotten about Dodge using the Watts link on the Durangos.

Seems to be a pretty simple setup. Not to mention parts are readily available.

I don't see why converting an 8.8, 10 bolt or whatever couldn't be done in a similar fashion.

I can't say I have ever noticed this.

A longer panhard rod will minimize this effect.

I know the long panhard bar will help minimize the side to side shift. I was just thinking outside the box.

I was actually watching an episode of "Car Fix" the other day. They were working on a Mercury Marauder. The Watts link that Ford uses is kind of strange. I'm sure it has to do with packaging and under car room. Anyhow, it kind of got me thinking.

The PT Cruiser also uses a Watts link. The Watts bell-crank is smaller, plus the laterals use tie-rod ends for attachment. I like it for being servicible and adjustable.

youngrodder is using one on his burb.....maybe he'll chime in..

a triangulated 4link will eliminate the ned for a watts link or panhard bar....

Sorry for bringing this back to the top but I just now found the relevant photos I was looking for. [I'm still suffering from the recent Photophucket phiasco].

This is the rear suspension on my drag car (A body - Chevelle) - showing the long panhard rod. I modified the rear control arms to be straight in the plan view, which necessitated the addition of the panhard, but helps the car resist twisting during launch. I also repositioned the control arm attaching points to modify the rear suspension instant center/percentage of rise to be more in line with what the car is used for now.

I took this opportunity to narrow the frame rails at the rear. The rear tires shown are 13.5 wide on 10" wide rallys and now clear the frame (no modifications were necessary on the body side).

You can see the suspension is sitting on sections of 4" PVC pipe, which allowed me to simulate the final ride height, facilitating the setup and fabrication without the body in place.
