Types of 4-Link Suspensions

[69-er]

We have decided to go get rid of the leaf springs on the 69 Camaro and go with a 4-link setup. I've never examined one up close or installed one before.

I've seen "4-link" and "4-bar" systems. It looks like the 4 bar systems have equal length links while the 4 links are unequal. I understand unequal lengths are more desirable for wheel hop. This car won't be thrashed at the track, so the absolute best performance isn't necessary. Or is it?

Also, tire clearance is tight, width-wise, so I'm not too crazy on using a panhard bar. We really can't afford any side-to-side movement during suspension travel. Are there triangulated 4 links out there?

If anyone can point me in the right direction to get started on my rear suspension education, that would be great!

Welcome to the site, and this topic has been beaten to death. Try using the search at the top of the fourm. That should give you at least 2 days worth of reading. Also post up some pictures of your ride in the project section.

Two of the most popular and proven rear suspension setups are from DSE and AME. I will be using he Art Morrison rear setup since it replaces those weak stamped rear frame rails. Both are triangulated four link and very capable.

Normally a 4 bar has very little adjustments where a 4 link has more.Have you looked at a 3 link or torque arm set up? Like http://www.speedtechperformance.com/...rod/prd170.htm or http://www.jakesrodshop.com/Products.html or a bolt in one https://securec20.ezhostingserver.co...id=25&catid=77

What's everybody's opinion on this?

How can it be so much cheaper than the others mentioned above? The guy has a lot of positive feedback.

^ that is a drag race set up. Really good for planting the rear on fast starts, not so good for going around corners.

I read that 4 bars are considered more for street use, (corners) and 4 links were for drag racing.

You might be right, but that looks like a 4 link to me. Ask the seller his intended application, get some stats (AS%) and see what he says...

[69-er]

Already did! What to you mean by "(AS%)"?

AS% = Anti Squat %
