I bet your butt dyno won't notice the difference between 3.73 and 4.10 gears.

Lot of money for a difference that will be hard to notice.

I can tell you 100% difference between my wife's 3500 dually and my 2500 srw. They are both 2024 and drive completely different.

You can do it yourself but figure 3 days if your first time.  Maybe 4 with IFS.   I’ve done so many now its a breeze with setup bearings.  Even put dana 70 gears in my front d60.  Goin strong after 10 years still.  Thanks Jana!

this truck pretty much only gets used for towing the boat or hauling stuff, so id bet id notice the difference for towing purposes.
it's not about getting faster, its about moving the torque curve a little bit
also, before someone says it...
i'm not buying a diesel

In Port Orchard, John's an honest dude.  Purchase the gears and have him do it.  He has fixed and upgraded a couple trucks for me.

I have regeared a lot of rigs over the years, in college swapped a 1990 bronco from 3.55's to 4.10's and it was almost imperceivable change. Changing from 2.73 to 3.55's in my mustang on the other hand...

haha, it had cheap 33's, I thought going to 4.10's would get it back to the was with stock 30's.  Prob should have gone with 4.56's or 4.88's.

Call Randy's Ring and Pinion. They'll tell you exactly what you'll get. If you're headed down to king of hammers maybe get down to 5.29s.. just left there today. Be in westport tomorrow.
