SNY SD UP Posted February 17, 2022 Share Posted February 17, 2022 If this is not the correct topic for this question, please let me know, and I will move it. Wondering what those with a similar TV have as a R-E gear ratios.

Steph and Dud B Posted February 17, 2022 Share Posted February 17, 2022 Our GMC 3500 gas (6.0) dually has the 4.10 rear end. The gas engine gets its best torque at higher RPMs than the diesels, which come with 3.73. Stephanie and Dudley from CT. 2022 LE2, Hull #1150: Eggcelsior.

John E Davies Posted February 17, 2022 Share Posted February 17, 2022 4.10 for sure, but even that is not the best if you have oversized tires. The current Power Wagon comes with 4.10s and 33” tires (2010 and earlier have 4.56!). Tundras come with 4.30s and that would be a better choice for a Hemi for lots of towing. My Land Cruiser has 3.90 gears and 33” LT tires, and it struggles, the 5.7 Toyota engine has peak torque at 2800 rpm, and falls flat below that. What are the ones in your truck? Are you thinking of changing them? That is a very expensive job with a very long payback, if any. I was quoted $4000 to install new Tundra gears. Edit, the stock Ram 6.4 truck engine torque peaks at 4000, that seems really high for a work truck. An aftermarket chip to increase the mid-range power would help, but, I personally wouldn’t do that while under warranty.

John E Davies Posted February 17, 2022 Share Posted February 17, 2022 I used to have a Ram, I don’t recall perfectly, but I think when you register your truck at the Ram owners website, you can view the window sticker and detailed specs for your truck. https://www.mopar.com/en-us/my-vehicle/dashboard/details.html That 8 speed transmission has a really low first gear, almost 5:1, that will be great for getting the Ollie started from a stop. That won’t help going up highway grades, but it will be most excellent at low speeds. My LC200 6 speed in contrast has a 3.3 :1 ratio for first gear 😤 John Davies Spokane WA SOLD 07/23 "Mouse": 2017 Legacy Elite II Two Beds, Hull Number 218, See my HOW TO threads: Tow Vehicle: 2013 Land Cruiser 200, 32” LT tires, airbags, Safari snorkel, Maggiolina Grand Tour 360 Carbon RTT.
