Jag IRS - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a Jag IRS to play with, and have been thinking about putting it under my glorified car. My truck will be able to ride fine with the straight axle if need be.

If I do it I have to widen it by about 2 inches a side, but I need my final wheels first. Not just the rollers I have.

Either rear end I have needs work. Along with a gear change to bring up to spec.

So with occasional heavy towing of 5000 pounds with a Jag IRS be a issue due to its swing axle set up. I plan to use RE6 bags, and dual shocks in the rear.

I am thinking of doing it because it is different, and I have a couple laying around.

Can't say I know anyone who's ever even thought of much less tried this.

I'm not sure of the specs on the jaguar axles, but Ford explorers and ford expeditions have had IRS for about a decade. If you search for that you will find plenty of people who have swapped the ford stuff into different cars. Maybe you can get some ideas from that.

I have looked at them, but no one tows with them I could find. Although people do tow with cuvs, and such with out issue.

The big difference is in the way the tires cycle during compression, and rebound. Which has me wondering if it will cause instability if I hit whoopties going down the freeway.
