Worth it to Re-gear?

Hi, I have a 1997 GMC Sierra C1500, 350 Auto. Since it's 2WD it has 3:42 gears, it also has an open diff, GM 8.5 10 Bolt. I'm planning on putting in a Eaton Detroit TrueTrac in to help with the winter and having fun (Canadian Winter). I average about 16-18MPG city and around 25-28MPG highway, with the 3:42 gears. I drive fairly aggressively though. Now I'm considering regearing to 4:10's but I'm not sure if it's worth it ($200 for gears, plus having to get everything calibrated). I drive about sadly 95% city (I live in a medium sized city, and avoid downtown as much as I can, so it's not "heavy traffic" driving). I do plan on lifting it probably a 2-3" lift and some all terrain tires, the 2WD's just sit too low. I run 235/75/15 Highway tires for now until probably summer. I do drive aggressively and like to play with my truck, would I notice a good boost in acceleration? Also would a "heavy duty" diff cover help at all with anything or is it more for a trail type situation?

In my situation, where I do drive fairly aggressively, mostly city, going to bigger tires, upgrading from an open diff to TrueTrac would it be worth while in your opinion to upgrade to 4:10's? I do next to nothing for towing and stuff.

What are the Advantages and Disadvantages of regearing from 3:42 gears to 4:10 gears? Thanks

Don't think you would be happy with the gears. I would leave as is. Fuel mileage would take what little fun you would have getting from here to there in a short distance just a little faster. Definetly wouldn't give more power. Stick with what you have in gears.

If you're going to put on larger tires you'll want to regear IMO. That 350 doesn't have a lot of power and will be a lot happier with a little help from gears.

 

You will lose some fuel mileage, but if you lift and increase tire size you're going to anyways.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      Interesting pivot.

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
