The Stovebolt Site Forums The Shop Area The HiPo Shop Jaguar IFS and IRS install on 58 Apache

I'm new to this site so don't know my way around yet I know it's been posted on here and I have look but came up short.
I started 2 months ago installing ifs and irs off a 82 Jaguar xj6. I got to say the ifs was scary close to fit just setting the frame I wanted to use the jags OEM rubber mounts this left me with three places per side that needed fab work. 1st A arm need to clear the frame on the top side.2nd just below the A arms the frame need to be tapered in about 1". 3rd I use some tabs for the front OEM rubber mounts. On the IRS I C notch the back and fit the hole OEM cradle in. I have pictures and some Videos if some one would like to see. If anyone has install this set up and have there truck on the road I like some feedback on how it rides??? I'm a long way out before the tires hit the road.

This one has been on the road for five years or so and has done great. Same XJ6 as yours and entire cradle was used on rear but the lower frame flanges were just bent down rather than notched. Center section on a Jag is a Dana so limited slip and cruising friendly gears were used.

Thanks that truck looks great. I'm struggling with the back control arms im guess that's what there called I'm wondering if I make my own and move them inbord of the bottom shock if they would hit the cradle under full suspension compression. I just don't like the stock one at all. My other idea is make some tabs that would straddle and stick out past the bottom shock bolt. Did you do something different here any ideas would be appreciated?

In the 90's Jag went to outboard discs and used what amounts to a 4 link set up. It would be feasible to apply this approach to the earlier inboard disc rear and the trailing arms and struts are much less bulky looking than the earlier stuff. The tubes welded between the lower control arms are temporary and used to keep the arms parallel to the floor during set up.

Messing with the geometry of an independent suspension system that has worked for years sort of defeats the purpose of using it, doesn't it? I'm pretty sure the designers who built it that way had more funds and research facilities available to them than the average hotrodder with a torch, a sledgehammer and a welder. Badger, unless you have the necessary engineering expertise to design a suspension system from scratch, and a really good fabrication shop available to you like Coilover does, it's best to leave well enough alone.

Thanks for the input you guy's I'm sure I will come up with something. Jerry as far as the messing with the geometry I assure you I'm not changing anything it's just one more thing that has to be done for the install. The arms only uses is the keep the rear end from kicking out the back end under hard launches in round about way. I fully understand what your are saying this why I'm trying to keep it as close to OEM as possible.

Ok- - - -the "control arm" you mentioned got me off on a different track. You're probably describing a sway bar or Panhard rod, not something involved in establishing the up/down arc of the rear hub.
Jerry

Yes. We would like to see the pictures.

Even though I've seen it in person a picture goes a long way in describing your control arms. Cause they are big ugly looking things on there now.
