Gears

[ford4wd08]

Hey guys,

I'm really thinking about doing gears in my truck. Number one when I did my bearings I found quite a bit of debris, bits of gear teeth, etc. and number 2 I want to unlock some of the low end on my truck again. Right now I have 3.55 in my Ford 8.8 in front and rear. I was thinking about upgrading my limited slip while I was in there too. My truck came stock with 255/70/17's and I am currently running 295/70/17's. I was thinking of going with 4.11. I think that would be a nice upgrade and make up for the larger tires. I believe I'll leave this job to the professionals because I have the lack of time, and I don't want to risk me messing something up with something this expensive on my daily driver. Here is what I am thinking of going with...

Amazon.com: High performance Yukon Ring & Pinion gear set for Ford 8.8" Reverse rotation in a 4.11 ratio: Automotive

Amazon.com: Detroit Locker 913A561 Trutrac Differential with 31 Spline for Ford 8.8": Automotive

Since I am fairly new to the gear world, as far as picking a setup for my truck, I was wondering if I could have some of y'alls input. Will all this work together? I know I would need a new instal kit and I plan on keeping the stock axle shafts. But I was thinking of ordering this stuff and taking it to whoever I get to do the instal and let them get the rest. Any brands that would be better over another? Thanks for all the help!

Give the guys at Ron's Machine Shop a call and they will walk you through exactly what you need. Probably beat the Amazon pricing too, tell them you heard about them on performance trucks.net.

I'm not real sharp on gear setups but I'm pretty sure Yukon is good stuff and the True Trac is pretty good.I really want to get one for the front diff in my burb some day,there are trails here where I could use one.

4:11s should make a big difference in low end grunt

...AND at the gas pump.

I expect to loose some, but I'm not doing so hot around town anyhow, I think it will balance out just because it's hilly around here and I don't stay in OD very often anyhow.

Any calculators to show the difference in RPM's out there?

YOu might lose a mile or two per gallon but the enhanced drivability will make up for it. It won't make a huge difference.

When I went from the KM2's and up a size to the Toyo's i lost about a mile a gallon. I get about 14 average know, I feel like it will be about the same, but with more power

Give and take,gain some here and lose some there.I really don't worry about fuel mileage,I know it's going to be bad but that's a price I pay for having the towing & off-road capability of my burb.

BTW....love my KM2s
