Truck is very sluggish off the line with the oem 3.08s on its stock 20s

upgrading to 3.73s will I also need the carrier? 
From what I’ve read 3.73s will get it off the line pretty quick, can anyone confirm that ?

Welcome to the site.

 

How about a little information about your truck?

Just the gears and bearings. The G80 locker stays the same for the rear.

 

If 4WD you'll need gears for the front too.

Greetings. I believe the carrier split is 4.11 check some web vendors. If memory correct. New gears need pinion depth shiming with a tool and measuring. Used gears have shims allreay set and on pinion. You will need carrier shims to set backlash. Just a new crush sleve done it b4. Have you tried manually shifting the trans to see if acceleration improves.. Are your tires taller than stock? Lowering overall ratio.?

Will the 3.73s make a difference for low end ? Very sluggish as is at the moment 

worth the swap?

Yeah, it will be a completely different truck with 3.73's compared to 3.08's.

Welcome to the forum!  Your stock combination gives you great fuel efficiency and should have plenty of power to get you first through the intersection when so desired.  (unless you are referring to racing)  I'd make sure your truck is working as it should before tearing it apart.  Perhaps test drive another truck with similar specs.

Yes the trucks working perfectly fine 

I just feel it real sluggish 

so I’ve read that 3.73s will make a difference 

 

coming from a 17 ram RT 8spd with the 3.92 gearing that would get off the line real quick for a stock truck

You could always go with 4:10 and fill up with gas twice a week.

 

I had a 3:42 in my 14 with a 6.2 and a 6 speed, it was quick for being a CCSB 4WD with 20's. Had a 2004 "shorty" SCSB with the 5.3, 4 speed, and the 3:73, fun truck.

I do lots of free way driving so 4.10s wouldn’t be the best route 

which is why I’m asking if 3.73s will make a big difference or not worth the $$

I could see it if you were pulling a load. For daily driver ??? . The 90s were about corprate fuel economy numbers and emissions . If its a 4l60 maybe a trans shift kit would improve shift pattern and power .

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
