Gears on a 99 IRS?

[shoobs99svt]

This may be all too obvious for everyone else... but I think that im still in the dark here...

Will ANY 8.8 ring and pinion (ie Gt solid rear) fit on the SVT IRS?

Anyone have a preference for a 4:10 set? Recommend a rebuild kit for the trac lock at 60k miles?

Yes, any rear gear for the 8.8 will work with the IRS pumpkin.

4.10s or higher for the 32V engine - a solid choice.

Might as well get the traction lok rebuild kit as well.
Also consider bearings.

Here's some more helpful info for the 8.8 (not IRS specific, but still good tech):

mine are getting installed this week. be ready to spend some $$$.
I got polyurethane bushings, heavy duty cross member, Billet FLow IRS Brace to all be installed at the same time. then the MM subframe connectors will be on the week after that.
and definitly go with 4.10's if you arent doing a power adder anytime soon.

Check CJ Pony prices...

at one mustang i shop i got quoted for 700 for a gear install on my cobra, but i turned them down and had a guy put them in for free at the dealership i worked at. it took him about 5 hours or so to get it perfect.

don't pay over $400 for IRS gear swap. it took me forever to find a place who at least wanted to do it. a lotta mechanics are BS'ers and don't know anything about the IRS and try to tell you how difficult it is. well it's not hard if you know what you're doing. shop around. I've gotten quotes from $400 - $1000
