Just like the title says I'm new and need tons of help. I basically want to learn more about my truck and what it has in it far as lift kit, motor, and what's needs to be done at what miles. I have a tahoe that I paid off and went into a dealer(empire Nissan) looking for a car but left with the Titan. I love red and it was big and already lifted at a price I could afford. The sales person didn't really know anything but how to make a sale. In fact he told me it was a 4x4. I don't know much about trucks but I knew it wasn't a 4x4. Anyhow I'm clueless about lifted trucks and would like help on how to keep it up. My tahoe is just stock with 20s(family suv). When I say keep it up I'm talking about the oils in the drive trans, lifted shocks and springs etc. Really love this truck so far and would like to fix it up more. I live in so cal if any one is local. Not sure of the name of my lift other than what's posted on the arm(cst). How can I tell if it's 3" or 6" lift? Also I keep seeing threads about body lifts, what's a body lift?
