It seems I can find steering racks that show fitment to both XJS and XJ6, but I have purchased lines before marketed for each that did not fit my XJS. While it would make sense to fit the same rack, I can see the angles in the XJS necessitating a different design.

Can anyone advise whether a series III XJ6 rack should fit an 88 XJS?

 

I'm nearly positive it will.

The Series IIIs used several different racks but as far as I can tell they're all interchangeable as complete assemblies and all will ir an XJS.

I think that some of the XJS racks had a different ratio....but, even if that's true, it shouldn't prevent a swap. XJSs with the 235 tires had spacers to limit travel so the tires wouldn't rub....but that began in 1989 MY so your '88 XJS wouldn't have them.

FWIW I have an XJ6 rack with V12 hoses and had no issues

Excellent, thanks for the info, Doug.

 

Didn't they change about 1982 or so from imperial to metric pipe thread sizes?

 

Could be, I dunno!

I know there was a change to larger tie rods circa 1983 or so. Or was it smaller? Gah!. I always get confused but I know that there was a change in that regard!
