You want disc`s, on the cheap
 

I`m posting this with some resevations, we all like having disc brakes, IFS, we would also like rack and pinion, forged A-arms....well if you are a little intriqued read the link below, you get, disc, IFS forged a-arms, coil spring, rack and pinion, 5 on 4.75 bolt pattern, track width is 59.5 inches, and being our frame rail are dropped a little for the current crossmember, this would probably drop your truck a little more sense this member is sligthly thinner by design, you need to figure the motor mount issue, I think they would be close to just drilling holes for the lower part of the mounts. The `64 to 66 front track width is 63 inches, this will offer a choice of a wider wheel without getting into the fender, the Jag XJ-6 is rated at 5800 lbs so your good to go weight wise, worth reading anyways...if anybody decides to go this route, please post with plenty of photos, ;)

I wrote that article. ;) If anyone has any questions, feel free to ask.

EDIT: The pics have better clarity in my original HAMB post: http://www.jalopyjournal.com/forum/s...d.php?t=571296

Well we thank you Reyals, I`m not sure why this hasn`t surfaced here before, great write up...;)

Reyals I do have one question, caster is there enough built in or would they need more per application, as some like a little rake to their trucks. ? After you have been driving this application, anything you would do differant..?

I think I remember getting around 5 or 6 degrees on the alignment rack no problem. Of course, the F100 frame is different from the C10 frame, but if anything, the C10 frame will accommodate the Jag IFS even better.

Here is a follow up post I made in the HAMB thread:

Weeeeell, it's been just about a year since the Jag front end went under the truck. Several people have been PMing me with questions and such, so I thought I would add some notes to this thread to keep all the info consolidated.

Thoughts:

The shock mounts have held up great so far. I've driven the truck hard, and there are no signs of fatigue at the weld joints. Not that they still cannot break; I just think they would've by now if it was an inherently poor design. Much of the shock force is in the upward direction anyway, so it isn't really trying to tear the mount away from the crossmember. That means less critical force on my beginner welds. ✔

The XJ6 springs are a touch too stiff for the weight of the F100. It corners like a frickin beast, but the ride can be jarring over really bumpy roads. Its still light years ahead of the straight axle, but I plan to look into alternative lower rated springs.

Speaking of cornering, the steering definitely takes some effort. I've concluded its actually a bit tougher than the stock Ford steering, but at a much quicker ratio. Remember though, I'm not running a power steering pump- just straight up manual steering a power rack around. Its kinda lame but I kinda like it. At least that's what I keep telling myself. I guess I'm too lazy to put a pump on it. Honestly, if your used to good ol Popeye manual steering, you can run the Jag rack without a pump and enjoy the fast turning ratio. Or just install the pump and fahgetaboutit!

Manual disc brakes on the other hand feel fantastic. Because the Jag calipers are so big, they don't really need power assist unless you want a super light pedal. I think coupling them with the 15/16" bore master cylinder was the ticket. The truck stops beautifully.

Lastly, if your planning to install your own Jag IFS, make sure you factor in enough caster into the angle of your crossmember. Don't count on being able to shim the upper arms enough to make up for poor crossmember positioning. If you're doing an F100 like mine, I'll tell you right now that with the crossmember sitting squarely on the frame as I have it, you will get away with just enough caster. If you don't run as much rake as I do, that'll help too.

That's all I can think of for now.
