I am almost done building a 48 GMC pick up & I am already thinking of making a major change when done.

I would like to do another chassis with C4 suspension. I would like to do this w/o bracket kits.

Do you know of a web site or info elswhere that can help me make the required brackets to adapt C4 suspension to a 1948 Chevy/GMC frame?

Unless you have a lot more time than Money $$$

It is usually more cost effective to just buy them........

Just my nickel.......

I am retired( Mech Engr) & have the time & knowedge to make the brackets . I have Miller 200 amp Miller mig, a 300 amp tig & a plasma cutter. I just need some dimensions.

Well....no responses! How about if we just stick to the front suspension. Any knowledge about installing the Vette C4 IFS. If no knowledge base how about comments on te bracket kits.

I certainly don't know... I "wimped out" and ordered the crossmember kit from Progressive Automotive for my '47 Ford though. It was rather expensive ($715.00) but then, I'm not an engineer... They show $632.00 for 1937-48 Chevy cars and $620.00 for 1947-55 (1st Ser.) Chevy trucks.

Don,

Sounds like an interesting project. Today I was standing under a Cadillac XLR and envisioning installing the independent rear in my '55 Chevy. You know the initial process you go through determining in your mind where and how mounting brackets would go. Since you have the time, skill and equipment why don't you engineer the mounting system? Would make an interesting project entry. Yes, this has probably been done many times and might be on the 'net somewhere. If nothing comes up why not give it a go?

I believe Bob at Progressive Automotive does this as a kit. I've stopped by their shop and Bob is a very decent guy. I doubt he would turn over the blue prints (he makes his living doing this) but you could always check.

Hi Russ, finally I found someone who has a Vette IFS installed in their car. Let me ask you some questions,

Is the Vette IFS all you expected as far as ride?

What was your total cost for all the parts to install using Progressive's kit?

Thanks Don

Don,

I've contemplated using the C4 as a basis for some projects.

It might be worth it to get yourself a complete C4, or even just the chassis. The early ones can be rather inexpensive, especially if the engine/trans are gone and the body is damaged. I've seen running roached '84s for under $2500. All you really need from the drivetrain is probably the differential and maybe the driveshaft so a motorless/transless one is fine.

A c4 damaged by an engine or interior fire would probably work great.

With a chassis in front of you, you ought to be able to measure everything to fab up what you need. When finished, you can sell off everything you don't need.

Just an idea...

I did a quick search of ebay.

There's a 1987 for (buy-it-now) $2400 w/o engine and trans - auction: 7989816597

A couple other c4s in the "parts cars" section that are pure auctions.

On collectorcartraderonline.com, there are several for aroudnd $2500 and a frame from an '87 (not sure what it includes) for $1000.

If you shop around, you can probably find as good or better deals locally.

Ride? HAH! It's not installed yet, in fact I just ordered it this week...

Here's my price breakdown so far:

• '87 Z-51 front suspension clip (E-Bay): $600.00
• Front crossmember kit (Progressive): $715.00
• Aldan aluminum coilover 550# spring/shocks (Progressive): $395.00
• Reman. T-Bird rack & pinion (Progressive): $147.00
• Bushing kit for R&P (Progressive): $18.00

Not included are boxing plates or swaybar. Total comes to $1875.00, about $300.00 cheaper than comparable Mustang II units, parts are readily available, and unit looks much more trick! One thing to consider, pre '88 units have 11" brakes and can fit a 15" wheel while '88 and later have larger brakes that will require larger wheels. My '47 will have an LS-1 motor and 'glass front end, so I'm not sure how the 550# springs will work out...
