Did you finish your regear? If so any words to share on the finished driving experience? Thanks
Listen... there are 3 things women want in a man, tall, dark, and runs some f***ing 4.88 gears!
So, short version, for anyone thinking about 4.88s, regardless of tire size, it's exactly like driving around in 5th gear. So if you feel like you down shift more than you want, or you tow and have to set the trans to 5th, then a re-gear will help.
Long version (you were warned) Transmissions are suppose to shift for efficient use of power from the motor, ours also unlock the torque converter (automatic version of a clutch) to bump up the RMPs to make more power as to not have to go all the way down to the point of dropping a gear. Then there is the aerodynamic factor, this is the real killer on the highway for our modern 200s, drop that wonderful aerodynamic nature of the stock bumper for a winch bumper, and allow all that wind to get caught up in the front fender wheels, you just drastically increased drag. Increase the distance from the bottom of the truck to the ground with a lift, increased drag. Add a roof rack, maybe even a RTT, have a rear bumper with tire carrier and jerry cans, all increasing drag. Off road tire weight is bad enough, then your are left with the increase in diameter, that's what people focus on, but in my opinion, it's not a big deal unless you are jumping over 5" in size, its the other things that get you. A gear calculator is a good place to start, but it doesn't take into account all the other things I talked about. And not to talk experience, but I've re-geared a lot of different vehicles, and if you just go off a rear calculator, you're wasting your money on a lost opportunity.
So for me, I can't stand when the trans has to drop to 5th or unlock the torque converter when just going up the small incline. It builds massive amounts of heat in the trans and is the same as driving down the highway with your foot half on the clutch, not a good idea. It's good for a stock truck with the computer thinking it will only last a short while, but on modified trucks, the TC will just hang out unlocked all day, pushing temperature over 200 degrees. I understand a mountain road will require me to shift, but I should be able to go up and down a tiny hill and stay locked in 6th for reliability reasons. With just a 33 inch tire, bumper, RTT, and a normal lift, on any road outside of flat Florida one, I couldn't stay in 6th for very long making it worthless. I averaged 11.7 MPG highway on the stock 3.90 gears (2008-2015 200s) because I was shifting so much, with 4.88s I'm at a solid 13 mpg on highway. While I wouldn't recommend diff gear to do anything for you off road, a 4.88 does make 1st gear low range sooooooo much better. Stock crawl ratio is 34:1, with 4.88s its 43:1. For comparison an automatic Jeep Wrangler Rubicon is 46:1.
Now for when people with '16+ 200 start to modify, it will be even a bigger deal, the 8th gear is .67 where the 6 speed's 6th gear is .58 so plus to the 8 speed, but the diff gear on a '16 are down to 3.30. Wow, so once bumpers, lift, and tires goes on a '16+, that transmission will probably never see 8th gear, so why not move the ratio band down to take use of everything?
