The 5.29 Mega Thread!!

Oh yeah man all the time going up and down I85. At ~85mph I want to say you're still under 3k RPM. No chance the engine could push the truck that fast at any lower RPM so in my estimation 5.29s actually allow you to use 6th rather than constantly shifting back down to 5th for a headwind or a small hill at higher speeds.

 

Good to know! What kind of mpgs do you usually get?

 

Driving 60 I can get about 17mpg, 70 gets about 15mpg, and 80+ takes her down to 13 or so.

Drag is roughly equal to speed^2 (an exponential function) and the truck is a brick.

 

Are you running with extra weight or snorkel or anything as well?

 

Yeah front bumper/winch, rear bumper w/ swingout and spare tire, topper and roof racks on cab and topper. Like I said it's a brick

 

Ahh so I may get some better mpg with no weight or extra drag

 

Yeah you should get much better than me. Still the drag=speed^2 applies to all. The faster you go the worse your mileage will be.

 

This makes sense to me since skeletron has has more weight and drag than my setup.

I have 285s, 5.29s, sliders, and front skid. Also tuned and get 21 mpg going 65, 19mpg or so at 70mph, 17-18mpg at 75mp, and 15-16 going 80-85mpg. Keep in mind this is all on summer gas. Winter gas and cold knock off 1-2 mpg on all of those above. I live in the mountains so love 5.29s. Only time I wish I had 4.88 is on long road trips where speeds are above 75. I only say this because I think I'd get better mpg. 5.29's at 85 drive so smooth though and hunting gears is never a problem. If I keep it below 60mph I can get up to 24 mpg on my trip read out. Speedo is calibrated too FYI and always confirm same mileage plus or minus 0.5 mpg by hand calculating. I'm a nerd to say the least.

 

I have been running the KDMAX Pro tune for a few months now with 5.29's and its definitely worth getting done. The gears and tune are the best things I have ever done to my truck.

 

Good to know! I’m up here in Utah with some decent elevation myself. I used to have a manual Tacoma and from what I’ve read the 5th and 6th gear are the same as the stock manual Tacoma. So I guess it won’t be too much of a surprise

 

Just got my install scheduled and they’re gonna do a cab mount relocation.

after install: SPC UCAs, cranking up the coil overs, going 34s.

 

Nice! I've read the same and that 5.29's on auto with 33's comes out to be from my memory about 15-30 rpm more in 6th gear at 70mph than the manual in 6th gear on stock tires? This was ultimately the reason I went with 5.29's over 4.88's, even though in my head 5.29's sounded like to much haha

 

ECGS is booking out on 5.29 installs until early/mid June now, FYI.

Just setup my appointment yesterday, was hoping for something a little sooner but it is what it is.

 

That's not bad at all. I'm in December for gear jobs.

 

You have no one else local? My buddy just had his gears done in a week at a local shop

 

ECGS doesn't sound like they even have 5.29's right now. I'm sure if I dug hard enough I could find a set to buy, and then schedule time with a local shop. Most everyone is 2-3 weeks out. Another two weeks for the wait is worth it at ECGS, warranty, and solid reputation.

 

Does everyone get gear howl with the 5.29s, is that just a normal characteristic or is it hit or miss? Do the 4.88s have less gear howl?

and does anyone have experience with the Yukon gears?

 

All gears seem to be hit or miss with gear whine

 

Yep, I get it if I drive over 75mph. If I let off the gas it stops, but as soon as I press the pedal again it comes back. Or maybe it's the other way around, I can't remember... Really not that big of a deal though. I have nitro gears if that makes any difference.

 

ECGS recommended against Nitro gears for 5.29, instead they said to go with Yukon. So I did.
