I have a 2004 Dodge Ram 1500 5.7L Hemi. I have Hedman LT Headers, flowmaster exahust(which i will be changing soon to something that helps performance, any thoughts on that will be helpful too), Trinity tuner, cold air, 125hp shot nitrous. Mickey thompson drag radials.

I currently have 3.55 gears and looking to maybe put 4.10 gears in. I still use this truck as a daily driver but love to take it to the track. would it be good for me to switch, what kinda of gains/loss would I take? any feedback is GREATLY appreciated!!!!

A prominent member of this board ( Cheffred) has a 2005 CC and runs 4.10's and 4.56's. He swears there is no downside to them. It's his DD, tows a boat and runs 12 second 1/4 miles... Pm that username or just search around here... he's kinda a post ho'... but in a good way. Everybody loves Fred, lol! He has been more than helpful to anyone who deserves it.

You might want to check out the Tech Help section of Randys Ring & Pinion website

Just get them, no downside. It'll make your truck feel 1000 lbs lighter.

ok, so if I decide to get them, has anyone ever installed them? I am pretty savvy under the hood, never done a diff though. I know the basics of what to take off and move but as far as putting the gears in, is it just a basic bolt on deal? I have seen people say use shims and such, so where am i putting shims, or just pay attnetion to disassemble and put i tback together EXACT same way just new ring/pinion??

How tall are your DRs? If they are in the 27-28" range as most guys are, it might actually hurt track performance (1/4 mile) if you swap to 4.10s. It might make you shift into 5th on the big end of the track, and fall on it's face going through the traps. There are several guys on here running 3.55s and 28" DRs with excellent results. I would get some opinions on this before pulling the trigger. No doubt it would get you out of the hole faster and be quicker on the street. I just don't know if it's the right move for quicker 1320 times.
As far as the install, it can be a very laborious and involved task. You would either need to do some serious research/studying of proper gear installation, have someone who knows their sh*t help you, or have them installed professionally.

I am not pulling the trigger just yet, i would like to get more opinions. The only thing I have bought so far is the wheels, but it seems since i bought 17" wheels most tires will be around the 26" range yes.

doing gears isn't an easy thing to tackle, I would get someone to do the swap that has tons of experience in that department. I did a gear swap and the pinion backed off and that set of gears were ruined.

I'm just saying if you were to do it your self you better check and recheck and recheck to make sure all the clearances are set and dialed in proper.

but my 2bits is take it to someone and get it done right the first time

I do have a 3800 stall TC. Since so many say have shops do them, I will more than likely get a shop to install them

never understood why it was called a stall
Because it "stalls" or hesitates the power being transferred to the wheels until a generally specific (I know, oxymoron) RPM range is reached. Same basic idea as you having the clutch disengaged on a manual and then engaging it at a desired RPM.

I was just talking with a buddy who was in the market for a new truck. After looking at Tundra's he ended up buying a Silverado...without driving a Ram...that is a separate issue.

What I thought was interesting is that the TRD Tundra (Toyota Respect Depletion) was running a 4.30 rear stock. It seemed pretty high in comparison to the other makes.
