Well today I made a few calls, the best price I got from a Dodge Dealer on a OEM LSD was 874.00 installed including tax. I'm having a hard time deciding what to do. They tell me that it will not affect my warranty. The question do I really need it, probable not, but??? I guess I need a push one way or the other. How many of you have the LSD and those of you that does not are planning of installing one. This is in a 2010 crew cab with the 355, the truck has just a little over 5000 miles.
