I need advice on IRS...

[1slow99]

I have a 99 cobra and I am going to install 430s. I want to do 03 half shafts and I want to know what locker I need to get? Thanks

The stocker from an 01/03/04 seems to work fine for most, what are your plans? Street, strip, hardcore strip, roadrace, autox? You obvously know that your diff wont work as the spline count is different than the 01s and up. Havent had many here comment on going to a truetrac, auburn etc on an irs since most draggers swap to a solid and then upgrade the diff. You can also add another clutch pack to the stocker if I remember correctly, sure someone else with more info will chime in.

On my 95GT's 8.8 differential, you could change the order of the clutch packs to make it less "slippable". Not sure if it still applies, but it still is an 8.8 differential.
