Installed by the Speed Merchant in San Jose. Work done in half a day. $430, cause I didn't remove it, I drove it in. Go ahead and criticize for paying extra. At least I'm comfortable knowing the whole installation is warrantied. I asked if the truck had been road tested in 4x4 and they said yes then pointed out a note the differential mechanic had put on the invoice, something like; "Warning, do not drive in 4x4 in the snow because this is like a locker differential, you'll just slide all over". Being a bit skeptical I tried it out when I got home. It is very tight. I won't try that again on dry pavement, but I'm sure it will be fine on loose soils. Calmini indicated that it could make some noise for a short time but I had none. I'll have to get down to Hollister as soon as possible to give it a good run.

Nice! I would like to see the side by side difference this makes with a stock rig. And, compare the difference to a rear locked rig without the front LSD.
BTW, you can get spare half shafts used from Autogator.com for $80
So, now you're ready for the spring Rubicon trip?

Rubicon, mmmmmmm. Maybe, as long as it's not the first weekend of the month. You know, military and all. What are the dates?
