Silverado 3.42 to 4.10 gears 

Half a second off the quarter mile with nothing but a gear ratio change is a huge gain! Thats badass man

This is a great upgrade specially if you tow/haul

My reg. cab came with 3:73's , it runs so good with just being bone stock, I hate to change it......I have a tuner and reset the shift points raising the shift range to 5800 or so, really help it...!

I thought about doing this to my 2010 Sierra 5.3 6l80 trans 2wheel drive double cab or ext. Because I do notice it has a nice sweet spot of efficiency around 1800-1900 maybe even 2,000. It’s catless and tuned just have 20’s stock height with a little rake and with street tires ls2. Im thinking after seeing you losing 2mpg. I get 20mpg with a mix of 65mph and 72mph. 18mpg at 80. Only issue is it has 310,000 miles now , I’m just worried with all the luck something is going to happen lol I stopped driving fast anyway due to the shake I never could cure

Informative video nice info thank u

3.73 perfect in between

But what transmission do you have?

Whats your opinion on 3.42 vs 4.10 gears on daily driving? How much of an impact do you think 1,000 RPMs vs 1,300 RPMs will make in 100,000 miles of usage? Im asking because I might switch my challenger to a higher gearing. I want to get a better 1/4 mile, but I also care about the longevity of it in a daily driver application. Do you think its even a good idea or should I keep it all factory?

What size tires?

You a local? I live in Biloxi

At 65mph. I’m at 2200 Rpm. On a Chevy avalanche. Anyone know why ?

Mobile tunnel!!!

Yall I have headers and my shi stays at 2k rpm to go 70
