Modular Conversion K-Member Info

Been doing some research and if worst comes to worst some of the conversion guys are using 96 and up stock k-members.

Hey there,

You can use any (V6 included, that is what I used) '96 and up stock k-member. The only thing that you must do to modify this unit for use with your Fox chassis is to cut approximately 1/2" of metal from the rear mounts and extend the corresponding bolt holes forward about the same amount. The modification and installation of this k-member in my Fox Mustang took maybe an hour and a half to complete, including swapping over the a-arms.

Take care,

JT

PS: Don't try to modify your Fox style k-member. What I've mentioned above is a gazillion times easier!

Just for the sake of it I used the stock K member and A arms along with the rest of the drive train. It gave the a car a mean stance. It does not rub anywhere that I have found. I do agree don't try to use the Fox unit it's a waist of time.

i bought a full upr tubular with 4.6 mounts for mine i did have a stock 96 k member but i wanted the stock geometry of the fox.

the sn-95 arms are 1" longer then the fox arms and with 17x8/245/45 17 they would have rubber on the fenders. but with the stock arms the just clear.

I agree that clearance can be a problem depending on the wheels you choose. Also, depending on which SN95 spindles you put with the differen arms, you can add another 1/2". The good news about some of that is the options for adjustable geometry that are available now. If you don't mind running coil overs, AJE (your site sponser) has a set of control arms that will allow you to adjust forward offset, caster/camber, wheel base and more. They also offer drop spendles, so that you can use the longer travel availability of the SN95 struts and still gain the value of the lowered center of mass. Have you measured the front and back inside clearance at lock-to-lock? You might find a bit of extra room there if you need it.

I am using the stock 2002 GT front end under my 87 and so far I have not had any problems. It's close but has not hit yet.

Did you go with the larger opening front finders, or the stock 87? I'm having a senior moment and don't remember exatly when they went to 16s ( and don't feel like looking it up)

Mine are the stock 87GT fenders but my car did have the 16" pony rims. The 17" do seem to clear so far.

I am new to this site, and just getting used to it, but would just like to state that this is a very interesting and useful write-up on the k-members. I like the fact that you are non-persuasive or prejudicial on either option, tubular or stock.

This k-member issue can be an obstacle so far as financial decisions are concerned. i. like so many are facing financial restrainsts so correct/informed decisions are always welcomed.Having said so; I have a question you may be able to assist with, not just for me but for other members as well.



Some people are lured in by the engine installation, and are unaware of the other issues and hurdles they must overcome.



As you state that v6 or v8 k/member will fit; that’s great!!This will allow more maneuverability in searching for a stock k-member.



I just have a couple of questions you may be able to shed some light on:



Are all of the fox lower control arms the same from 79-93, or would you recommend only the 86 &up.



Is the geometry the same for the fox and sn95 l/c/arms especially wheel set-back and wheel spacing in the wheel arches.



If using the sn95 power steering racks are they the same length, or should the fox body inner tie rods be used.



I have chosen the AJE k-member as it seems the way to go, lighter, more room for starters and headers, more options you can run Ford, Chevy, s/b or b/b engines, and supposedly better handling.



Would you recommend the AJE road racing braces for rigidity/stability issues?



Normally i use only stock parts in anything i do, but changing an o2 sensor or starter in an sn95 car is not 10 minute job. I like stock as it is usually cheaper and sometimes more reliable depending on what you use, and plentiful in the boneyards, which gives maneuverability when cobbling something together to see what fits.



Thanx in advance for any assistance rendered in clarifying these concerns.

I have not tested the V6 k-members but I would imagine they are the same. Any GT. Cobra, Mach 1 from 96-04 will bold in to a fox with slight modification.

Are all of the fox lower control arms the same from 79-93, or would you recommend only the 86 &up.

Your talking about the A-Arms correct? I would use the SN95 a-arm. There about 3/4" wider but have better geometry


Is the geometry the same for the fox and sn95 l/c/arms especially wheel set-back and wheel spacing in the wheel arches.

No different. You can notice the handling difference. I run a SN95 front with coilover and the cobra brakes. works fantastic. Wheel spacing is identical to stock and centered.

If using the sn95 power steering racks are they the same length, or should the fox body inner tie rods be used.

Not sure on SN95 but with the Mach 1 rack i just cut the outer tie rods shorter. My brains telling me to say its ok as is.


I have chosen the AJE k-member as it seems the way to go, lighter, more room for starters and headers, more options you can run Ford, Chevy, s/b or b/b engines, and supposedly better handling.

I dont think there better that any of the others. Customer Service comes into play. Dave Zimmerman from team-Z helped a lot.


Would you recommend the AJE road racing braces for rigidity/stability issues?

If you want road race Maximum Motorsport is best. Most tube k-member are designed for drag purposes.

hey thanks a lot for the info, i'm not concerned about road racing. with the AJE sitting on the floor, i was wondering if it was solid enough for daily driving. i thought it may be, but was uncertain.

What modifications are needed to use the 02 mustang k member on a fox? Mine is sitting on the lower mount and the upper is about 1/4 inch off??

I already cut short and moved over the boltholes on the lower so all holes match up. It's just the 1-4 inch higher. I plan to just use spacers. Will that make any other issues arise?

I have a bit of a strange question. Is there something technical that prohibits using the sn-95 modular k-member and the fox body A-arms?

When I had a stock 96 n up k member a
Only thing done to it was enlongating the lower bolt holes on the k member. Trimming some of the bracket off. And it slid right into place. I don't have old pics otherwise I would post them. As for using Fox a arms on a sn95 k member I believe they bolt right in. But u might want to use the sn95 ones for a bit better geometry of the suspension. Also when using a sn95 rack just trim the ends about a inch and use sn95 tie rods to mate up to it. Aside from the MM steering shaft for sn95 to Fox column
