    I have done a number of searches looking for information on the Jag IFS swap into various vehicles. It's my understanding that the Series 3 XJ6/XJ12 seems to be the most popular donor vehicle. This suspension was used between '79 and '87 on the XJ6 and through '92 on the XJ12.
    I am wanting to know if the earlier Series 2 front suspensions can be used. Are there major differences between the Series 2 and Series 3 IFS units.
    I hope that someone can provide some useful information.
    Thanks, Tim

    That thread is about IRS he is looking for info on IFS. I think TMAN did something once on his chevy. Look up him.
    I may be wrong though. I was once before.

    Series 1, 2 and 3 XJ6 or XJ12 - all the same. XJ-S - all the same.

    The only difference is that V12 cars had heavier front coils.

    No, not if you are referring to the front or rear suspensions of Series 1, 2 or 3 XJ6's or XJ12's, or any of the XJ-S cars (6 or 12 cylinders).

    E-Types (again, Series 1, 2 or 3) had different front suspensions and a narrower rear (of the same type).

    There are also some other Jags that used these same front and rear ends, for example the Mark 10 IIRC.

    plym49 is correct. the front suspensions on all of the series 1,2 & 3 along with the XJ-S type cars interchange with only spring differences. The rears same thing along with the MK-10 and 420G. The other two track widths are the Six cylinder E (the narrowest) then the V-12 E and the 3.4/3.8 S-types and the 420 (different than the 420G)

    The MK-10 Front suspension is NOT the same as the XJ-6/12 - XJ-S. Although the MK-10 front suspension is good, it is hard to mount. It does however have a forged I beam crossmember.

    Thanks for all of your responses. I'm in the process of gathering parts for my truck project, a '50 Ford F1. Still looking for the Jag IFS and wasn't sure what front units were the same. I knew the Series 3 IFS was being used in the truck swaps. The Ford Truck Enthusiast forum has been a helpful resource but The HAMB can't be beat.
    Anyone know of a Jag IFS that's available? Thanks, Tim

    Tim, I found one on C/L for 300$ offered him 400$ if he delivered it, cheaper than buying the rear out of a junkyard. 74 xj12l w/title it might run with new gas, sat in a garage for a couple of years older couple with health problems owner gave it to the neghbor for helping around the farm. He was 70 miles away in Mo. your should be able to find one too! tt

    I've done one on my 50 chevy sedan and one on a 50 Ford F2 Pickup. Also have magazine article on fitting one to a 50 pickup. Main difference is the width. Series 3 I believe is wider.

    That's actually a desirable car. You can make plenty parting it out. Or resell t to some Jag enthusiast who will restore it, and then use the proceeds to buy the pieces you need to do your swap.

    Series3 is best. Series 2 &3 have ventilated discs & 4 pot calipers, series 1 brakes are solid with 3 pot calipers, not as good. Series 2 steering rack has a longer input shaft area. I have put a series 3 into a 36 ford coupe, a bit wide, but with factory wheels it is OK, steering column position is very close to original.

    More neat things about Jag suspensions: Chevy front wheel bearings. Chevy 4 3/4 bolt circles (although the center hub opeining is a different size).
  23. that answers the question "will it work for my 38' ford truck"? answer "too wide.":(

    Are there any Identifing marks that will tell you what Series your looking at with out getting into the brakes. Or is there a code on V.I.N. tag? :confused:
    Anybody know how these would mate up in a 57chevy.

    I'M Speaking of I F S rear doesn't look to bad pretty straight Forward.

    I would not get hung up on which one it is. The differences are insignificant, and all of the parts are interchangeable regardless. Even the 'worst' Jag brakes are light years better than anything else you will run on a hot rod.

    Get one at a good price, don't obsess about which one it is, and enjoy. You will never regret it.

    how are you mate, I am working thru the process of putting a xj6 front end into my 52 chev, the only snag i have is that the springs are obviously stiffer , the jag motor being heavier and mounted further forward. do you have any suggestions for different springs . any info would be of help.

    cheers
