If you have a SRT8 you'll need the rear half of a RT halfshaft (different bolt pattern from SRT8s). I have this setup on my '07 SRT8 (after destroying stock halfshafts and diff at the traack) and it went in without a hitch. Small price compared to Quaiffe install and DSS halfshafts. Nice option for those on a budget. Unknown what power level the halfshafts will standup to but Inferal at Lxforums ran 11.54 w/ 1.6x 60' last week with this combo. I spoke to Ted yesterday at ALLUSA and he said there are a couple of these differentials in the system and he could probably get one for you in the next couple of weeks. So if you are interested order early as there is are lots of folks interested in these and they only have been released in small batches so far. There are a bunch of install threads about this over at Lxforums.
