I’m guessing overall, 3:92 LSD 6 speed
My truck is a crew cab 4x4, and I will be levelling the front next week, 2.5 inch. I do haul during the hunting season, not often. It is an everyday driver. I’m trying to find the balance between performance and economy. I am currently equipped with 3:55 and no LSD (with the 4WD Auto) 5 speed. My fuel eco is terrible.What kind of weight and size will you be towing? I'll soon sound like a broken record around here, but when you talk about gearing, fuel economy, driveability, performance, etc., you're talking about having to make compromises somewhere at some point. You just have to pick your priorities in order and stack the deck to fit them. It's very logical to try and achieve the best in all categories, but it's usually a juggling act, and something will have to give a bit. The heavier the load you'll tow, or the bigger and less aerodynamically efficient the towed item is, the lower the gear may have to be. Plus, how big is your Ram? A full-boat, 4-door, 4WD, fully loaded pickup is going to suck some more power and fuel efficiency out of the engine and may also need lower gearing. My '12 Express 2WD with regular cab and short bed pulls my slightly-over-5000-pound travel trailer with ease with 3:55 gear. Your needs and results may vary.
By upgrading I meant trading in for a 2012I'm not trying to be a smart ass but I think you got your buying process backwards. I think you bought first then decided what you needed instead of deciding what you needed then went out and bought something that matched your needs. If you are going to switch both front and rear diff's to 3.92 and add LSD and then change from a 5 speed to a 6 speed, I think you should seriously think about trading trucks. Your probably talking about 5-7.5K---if you buy all new parts and have the dealer install them.
