The GT may or may not have a T-Lok, and even if it does, chances are the clutches would have to be replaced anyway.Dustang99 said:Alright so I'm fixing up my 1999 V6... I haven't done much to it, I've only got dual exhaust and it's a stick. I'm planning on putting an x-pipe on and adding an intake real soon. I'm planning on doing much, much more to it, but my question is, do I need to get a GT axle to support the extra hp? I've heard of people's V6 axles snapping with very minor mods. And if so, what all comes on a GT axle? I'm supposing the t-lock will already be on there? And what else would I need to get to complete the change-over. If you could give me a price on it, that'd be great too. Thanks.
-in 2001, the axles are 28 spline, the same ad the GT.
You need to be putting out a LOT of power before the rear end will give up. (Around 300+ for pre-01s, 375+ or 400+ with a girdle).
You can pick up a kit from stangparts.com, or just get the entire axle assembly from a salvage yard (axle, housing, shocks (including quads) hubs and discs. You may want to use new fasteners.
