IRS question - would this work?
 
I saw a 1982 jag xj6 for dirt cheap and had a thought. My sons want me to buy it so they can take it apart, but I know it has an IRS. Can this be used on a cobra kit? If so, they could sell some parts and put the money towards our cobra project.

So will this IRS unit work for a cobra? Any help or thoughts would be appreciated.

The major components can be used but you'll find the XJ6 rears are too wide for a Cobra. The axles and lower arms can be shortened but that needs to be done professionally and can be costly.

Does that have a 4HU Nick?

I believe it has a 4hu but the track is 58".

mickmate 02-08-2010 07:46 PM
Yes the pumpkin is the same casting the 4HU. The other problem with the XJ6 rear is the open rear end and the tall ratio probably 2.88. A 5 speed would be really the deal in front of it. Track is about 52 on the XKE.

Wow, that is quite a difference. Maybe I should just stick with buying the one that comes with the kit.

Thanks so much for the input!

Hi Pete, When I built my cobra I got a complete XJ6 rear end. It was a 3.31 ratio. You can tell ratio by looking at the metal tags that are attached to the diff cover. I sent my control arms to Ron Butler, Cobra builder, now Retired, and he shortened them for me. See my IRS photo in my Album.

I spoke to Ron today and he will shorten both the control arms to the XKE specifications for $200 + shipping. He also has the correct half-shafts for sale at $250.00 for the l & R pair. Seems like a fair price to me.

Ron is a gentleman to deal with and his work has always exceeded my expectations. He is in California, call him he said he would be happy to take care of you. 805-649-6000 He was one of Carroll Shelby's crew in the hay-day of Cobra racing. Please tell him that Arthur Mitchell referred you.

Hi Arthur,

Thank you so much for the tip. I will certainly give Ron a call and see if we can make it work!

If you buy a kit from E.R.A. they will shorten the arms and shafts to the correct size for free.

Actually, ERA will do this if you buy their mounting frame for the XKE/XJ6-based inboard-brake rear drive and suspension. (XKE Series I and II control arms and halfshafts do not need to be shortened, but the later series do.)

I thought it was a good deal, and I'd do it again.
