Was looking into re gearing, but that’s not something I want to do myself and don’t want to spend 4-5k.
Unless someone here wants a side job or has a good rec for good work.
I plan to source a full rear end and front differential with 4.10 gearing, and swap those in, which I do feel comfortable doing.
My question is I seem to be getting conflicting info about what year trucks will work. I understand I need a 10.5 14 bolt rear end…but I’m seeing more from 2001-2006 trucks than the 2007.5-13 ish trucks.
Any info would be appreciated. Thanks

Buy the truck you wantI own the truck. It’s fine for what I need but this would be an improvement.

You’ve never remodeled a kitchen or bathroom ?
Swapping front and rear difs is a single afternoon job but appreciate it

Maybe give a call to one or two close by and ask what years will interchange and see if they have any in their yard.
Then you can decide if you want one from their stock or if you want to find one privately, but at least you would know what years would work.

Have you tried a gear shop? I'd think you could do front and rear R&P for $3k'ish, maybe less.First spot in issaquah wanted around 7k which is why I looked down this route.
Waiting on a few quotes from some places up north

He has a Facebook page that's called Kaiser Performance if you want to check some of his work out. It's a bit of a drive but might save you some money.

I don't know anyone close to Renton, but there is a guy west of Portland in Beaverton/Aloha area that everyone down here uses. Jeff is his name and Kaiser Performance is the business. He does excellent work and has done 10-12 regear projects for me and my son's over the years. The last gear set I had done by Jeff was in my Tundra 2 yrs ago and it was 529 front and rear gears with ARB in the rear and all new bearings, I supplied all parts and I it was about $800 out the door. I pulled both diffs and delivered to him.appreciate the info, ill look into him

I don't think you'll get front and rear re geared for less than 5k. Maybe you could pick up a wrecked 3500 and swap yourself? Most are diesel though and will have about the ratio you have already. Remember, 4.10 gears were more common when the speed limit was 55mph and trucks didn't have 10 speed transmissions

Plus the front end is IFS with torsion bars so will probably be more costly to source one with a 4.10 gear.

Randy's Ring and Pinion in Everett. Call them and they'll tell you the exact ratio which would benefit your truck based on tire size and highway speeds. Been a while but, I put a Eaton Powerlock in my F 350 and I think it was about $2,000 and I had a shop install it.4.10 was an option for 2001-2010 2500s, so they are out there.

the rear axel width was my main concern of which truck to source out of, as i know the innards are all pretty much the same for 14 bolts.
i have a few requests out for quotes, but ive been able to find front and rear 4.10's for at or under a grand for both.
add in a little for fresh fluid and seals and its a hell of a lot cheaper.

I'm not positive but, I think the final drive ratio on the diesel vs. Gas transmissions differ. Then, while the 2001-08 may fit, they had a few different transmissions through those years. I've owned a few and still have a 2002 2500. It runs a lot higher rpm at 70mph than both the 2003 2500 we had and obviously the later Alison 6 speeds and now the 10 speeds.

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.

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

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!sounds like you want a little side job :chuckle:

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.
