04 Dodge Ram....a little at a time..

---------------------------------------------Originally posted by loudcivi'm assuming you verified your stock diff gear is a 3.55? 3.92 is a factory option, but probably not likely since you have 17s from the factory. by looking at your chart, you on stock tires & gears @ 70 mph your engine is turning 3,032 rpms. w/ your 24s & 4.10s at the same speed you'll be turning 2,200 rpms. thats less than 200 rpms more, hardly overworking the engine IMHO. 4.56s are tempting, but its definately going to be more noticeable at highway speeds. when i was deciding, i also took a mental note while driving how much 200, 300, & 400 rpms more sounds like while driving.---------------------------------------------I called the shop and had them tell me what the rear gear was, it was in fact a 3.55.The guy who is building it said that a 4.10 should be good enough since I will only be pulling a trailer a few times a summer.  he also, said that a jump to a 4.10 might not kill the gas mileage but with a 4.56 you would really tell it. so i went with the 4.10, I hope I made the right call..... He also, said that moser would not make what he needed if i went with taking 2.5" out of each side, so he had to go with another company and ended up saving a little money. it will be $1700. and everyting becides the housing will be brand new with a lifetime warranty BTW thanks for all the input Adam!!!!!  you've been a big help!!!!

i hope $1700 includes a new lsd/posi unit & not just gears and a narrowing?

There deal with Strange Engineering for the axles, saves me shipping as well. 

I'm not sure what the deal is but the man said that if we went with moser it would cost and extra $1000.00   he said you would have to change a bunch of stuff up.....

I call BS. Moser made me new axles the first time around...and just resplined my axles less than 2 weeks ago. First go around was 2 per side...and they just did another 4 per side...r the reapline was like $150 shipped and the new axles were around $450 shipped both ways. Sounds like someone gets a better discount at Strange if u ask me. I just got my axles from Moser last Friday before Texmex.

hmmm.... I dunno. I think even Taylor said he had some made 2.5"  shorter from moser
