I'm getting way ahead of myself here, but has anyone ever considered swapping an '80s Corvette independent rear suspension into an Eagle? I think the Dana 44 C4 would be an awesome (and rather expensive) idea to put into my Eagle if it could be made to work, especially for when I can install a stroker engine. The Eagle has excellent handling with a solid rear axle, but an IRS seems like it could hold a lot of potential. The Corvette axles can use 3.07 gears, which is what I feel would be perfect.

I don't plan on doing any serious rock crawling, but it would be able to handle any towing or light trail riding I'd throw at it. Not only could it improve handling, but it would also add disc brakes to the rear. Does anyone know the widths of the D44 C4 batwing to compare with the Eagle frame, and/or the width of the Corvette axle compared to an AMC 15?

I considered an IRS swap one night, but I didn't do a whole lot of research. I thought the Explorer or Mustang 8.8 IRS might make a good swap, but I have no idea on how big they are and the difficulty involved in installing one.

The Corvette irs is much simpler than the Mustang's, and I feel like it wouldn't sacrifice quite as much ground clearance. Plus, the Corvette has a similar looking frame to the Eagle and it would only require a few brackets being welded in. I believe the Mustang irs would require adding structural cross bars underneath.

I wouldn't ever want to put irs in an eagle. you loose off road traction. but then again, my eagle sees more dirt roads than most of the other folks on here. if your just an on highway car, sure, try it. my only issue with it is, corvette irs is designed to have very little suspension travel. they sit with the cv shafts laying strait out. (or really damned close) to work in an eagle, you would need to have it drooped down a fair bit to maintain factory height. if you were to lower the front end also, an eagle (sx4 or 2 door sedan would be best) could make for a totally BAD ASS auto cross car. drop in a turbo 4.7 stroker, pro built aw4 with paddle shifters, lowered, 4 wheel irs/disk brakes with some 17" wheels with maybe 245/45/17 tires, you could piss off some sti guys. :banana: :amc: :lmao:

Look into a Jag rear axle. That said, unless you want a low rider with limited axle travel, I wouldn't do it. Vettes with hitches usually do a solid rear axle swap.

Having a GM alternator is more than enough GM in my Eagle.
(I finally got one that works after going through five or six 12si's.)

:facepalm:

Used or reman? I rarely have probs with them unless the connector for the regulator or battery wiring is fubared. Loose main post on the alt is another.

Mostly used ones from Eagles I've owned and driven or stripped for parts. The one I'm using now has a "Rebuilt by Bosch" sticker on it. It has a different look than the regular GM unit.

the jag rear also has inboard brakes ....... and that's another cool factor that you'd get as a bonus :mrgreen:

That does sound pretty cool. I definitely don't want to lower this Eagle though, it would have to be a different project. I was thinking it would need to be dropped down a bit to keep the stock height, but I hadn't thought of it reducing suspension travel, which sucks.

However, I don't quite see how it would reduce traction offroad. The wheels travel independently, which prevents potholes and terrain from throwing the car off course. When a solid axle hits an object, it affects traction on both wheels.
