Saw a GMC commerical last night and they have the LSD as a standard feature now. I wondered if GM is causing a shortage since both Dodge and GM uses the same rear?

 

this might sound dumb, but what does LSD stand for?????

 

limited slip differential (?)

 

LSD = limited slip differential...
on the 3.73 thing, I emailed dodge through the web page to find out what was going on. They sent a couple of canned (pre generated) responses back basically telling me they can't answer technical questions. I talked to my sales rep her response was most trucks she sells have the 3.73 rear. (my truck has the 3.73)
