Anything else you recommend I add while doing the sn95 rack?The information below is something which I’ve been able to confirm, but haven’t had the chance to change on the MM website yet.
With the lone exception of the 2000 Mustang Cobra R rack:
All 1999-2004 Mustang racks have the same valving.
All 1996-98 Mustang racks have the same valving.
All 1994-95 Mustang racks have the same valving.
The differences in SPR codes from the different racks within the ABOVE year ranges is due to differences which don’t matter to us, such as the thickness of the steering rack limiter clips.
In another thread he mentioned the racks getting more road feel with each generation due to the old guard at Ford, who insisted on comfy steering, started to retire.So, Jack, do you have anything that details the differences between the 94-95, 96-98, and 99-04 racks? In other words, do I want to consider upgrading my '95's rack of it ever needs replaced? Thanks.
Was this directed toward my question, Jack? (Is it worth upgrading a 94/95 to a 99-04 rack?).......
I don't have enough data yet to accurately answer that question. The differences between the valving in the different groups is not that large. This requires a lot of racks in each group to be tested until you have an average behavior for each of the groups established.
I think it was. Sounds like he was saying at this point it's inconclusive.Was this directed toward my question, Jack? (Is it worth upgrading a 94/95 to a 99-04 rack?)
I agree. I really like the steering and feel when driving my 03 cobra. Then drive my 90 coupe and it just leaves a lot to be desired. It feels sloppy.That is a big revelation, nobody with a fox should suffer crap steering again.
Ditto, now go find a 1990-92 Mark VII and build that. Those don't need the expensive hybrid steering shaft. Those you can use any 94-04 steering shaft with the racks, and the existing TRE's.That is a big revelation, nobody with a fox should suffer crap steering again.
Jack thanks for the tip. I didn’t know the sn racks couldn’t take any pressure on the input shaft. I wondered why you incorporated the telescopic feature to your steering shaft but now it makes sense. For me building the solid Fox shaft was easy just cut and tig weld it together I have a circle track style splined hub and removable wheel so clocking the wheel isn’t an issue for me. But I don’t want to blow out racks from undo forces being applied where they’re not supposed to be. So you will probably get my business when I buy a rack. Thanks for all you do and the knowledge you share it’s appreciated 👍🏻.SN95 steering racks have no capacity for end thrust on the input shaft. If you apply one to the rack, you will ruin it very quickly. Note that the SN95 steering shaft has telescoping sections which slide fairly easily to stop any end thrust on the input shaft. If you install a SN95 lower u-joint on a Fox steering shaft, there is almost necessarily going to be some end thrust on the input shaft because the Fox shaft doesn't have a telescoping section. It has a rag joint with a very small amount of end compliance.
