In want to know what rear end i have in my 2006 ram 1500 4.7 2WD 4 door slt pickup. I want to put 4.56 gears in her so I can start towing my 19' travel trailer. Need to know what rear end so i can begin shopping and pricing installation of gears. Don't know if she has LSD or not. Gonna check tonight. If it does ill pull the diff plate and inspect it. Gonna go with YUKON gears. Maybe a Detroit LSD I don't know yet. But I'm familiar with Dana diff models. Haven't really had the time to crawl around under it and look for any markings. Just posting this to see if anyone knows off the top of their head. Mods- if this is posted on the incorrect spot can u pm me and let me know where it needs to be thanks.
