Re: Flat Tow: Locking Hubs on the Rear Axle ????
2 years ago, Currie built me a 9" and I decided not to do this. I decided not too because the hub would be the weak link in the setup. HOWEVER, I regret the decision because if I was blowing hubs, I could always switch over to drive flanges. This would then be slightly stronger than non full-float. Besides, swapping a hub if necessary is quick (most of the time you can continue on with 3wd anyhow).
If I could do it again, I would do the full float conversion with rear hubs (since I flat tow my Jeep anyplace longer than 100 miles). I still may do it since I don't plan to ever have a trailer (too wide/heavy/tall, storage, $$, etc).
Last I talked with Currie about this 2 weeks ago, the cost for this kit on a 9" was about $1k (afte the fact). It IS a bolt on kit. You save some money if you modify your drum at a machine shop yourself. So figure on $750-$800.
