Leaf Spring to 4-Link Conversion for Rearend....Worth it?

I'll be replacing my rearend shortly and I was wondering if the conversion from leaf spring to 4-link is worth it. I've seen a kit from CPP for 799. It seems kind of high, but I'll be driving this truck a lot and thought that if it makes a really big difference in ride, it might be worth it.

Has anyone out there done this to their truck? Mine is a 53 Chevy 3100. It has a Mustang II front end, 350/350TH. It doesn't look like the conversion would be too difficult to do.

What do you guys think?

depends on what your using the car for realy

personaly speaking....if its just gonna be used for daily driving and isnt going to be overpowered or expected to launch at the track, i would rather build a 4 link myself, using stiff rubber bushings or polyurethane bushings, instead of the heim joints as full race 4 link would have

i know if you look around the web, or even just a search on this site would turn up plenty of details on how to build your own setup far much less then 900

personaly, i have sitting in my garage a set of almost new jeep cherokee front control arms , taken just because they were going to be used to build a ustom set of control arms for the truck i had

In my opinion, it's hard to beat a good leaf spring rear. I don't think you'll achieve a better ride with a 4-bar, but it will lighten your bank account considerably.

Even at the dragstrip, I see cars and trucks going into the 10's on leafs and hookin' up with Caltracs or some other anti-wrap device.

I think if I were bound and determined to spend money on the rear suspension, I'd order a new set of leaf springs from these guys....

Not all 4 links are created equal. There are styles designed for specific purposes, and a drag race style will not perform the same as an equal parallel set up that is used for air-ride.

If your sole concern is ride, consider softer leaf springs and softer shocks.

There are companies out there specializing in the 53.

Thanks for all the posts...

I've started looking at new leaf springs for the rearend.

Currently I have lowering blocks in place and so I'm checking into the lowering springs. I'm not exactly sure what I'll end up with yet.

Doing a leaf spring conversion would be a lot easier than doing a 4-link conversion, so I may go that way if the ride can be okay with the new leaf springs.

I'll probably start the ordering process after Thanksgiving sometime.

I love riding around in the old truck! Is this fun or what!

Check and see what Posies might have. They have a super slide spring that eliminates bind and rides smooth... but I don't know about your application... but you can learn what to look for.

Also there is such a thing as "lowering springs" that have the forward spring eye centered on the leaf and a reverse eye on the shackle end. This reduces the need for lowering blocks which can cause wheel hop, etc.

4 link

I recently did a 55 chevy, ponied up the bucks for a complete Jim Meyer front and rear. The rear was a 4 link/panhard/sway bar/9" posi/adjustable coilovers/discs. Looked cool, didn't notice any difference - I drove it daily to work. I'm using leafs/sway bar on my new rod, easier to run exhaust too. FWIW, Bill
