I'm not happy trailering with this truck.  On hilly backroads I'm either redlining in 2nd or dieing in 3rd.  So I thought changing the rear might help.  I spoke to a Chevy service rep who told me I would have to change the gears in the front as well due to 4wd, and that this would push the cost towards ?k.  

Does this sound right?  

Is there a better way to go?

The trailer weights >5,000 lb, and the truck is as described in sig.  

Thanks.

The problem with the old TBI's is that the redline is 4000rpm.  4.10 gears is the best bang for the buck, especially for towing, but ? is crazy.  The gears itself can be bought for ?.  You'd need two sets-one front diff and one rear diff.  Installation is a pain in the @!#.  I highly recommend hiring someone to do it.  I would say ? is close.  

www.summitracing.com has Richmond gears for ?.   Most big service centers can do it.  2 grand is nuts in my opinion.

? is way too much for a gear swap!!  Try to get hold of kaspar139, via messenger.  He's done a ton of shopping and price checking on gear swapping lately.  I'm sure he'd share what prices he's found.  I think pastmaster is more in the ballpark-

This is just a thought, but if you aren't towing all the time and your running stock size tires then maybe 3.73 gears would be a good comprimise.  Otherwise I'd reccommend 4.10's...  You'll be turning alot more rpm's though, especially at highway speeds!!!

Go with the 4.10's. I had 3.73's and they were adequate, but the 4.10's are better. If you're running 265's it might not be too bad on the gas mileage. I'm running about 2200 rpm's at 70 mph with the 265 TA's. 2k for a gear swap does sound pretty high.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
