The 5.29 Mega Thread!!

Just logged my best mpg ever since my switch to 5.29’s Lift and Heavy ass 285’s (33’s)

logged 18.6mpg. 98% 1 lane highway, 2% freeway. On 141 mile trip. This is Speedo corrected for tire size actual #’s

recently switched to the valley runner tune and I deff think I’m running about 1mpg higher than on ovtune 2.0F

truck looks fairly stock in stance but has estimated 300lbs of added weight normally. This time the truck was loaded with a full bed of gear and family of 4. I’d estimate my payload to be around 800lb over stock this trip.

 

Stock gears is out and 5.29 in its place. Thanks to ECGS making the process easy and painless.

 

What did you use to correct the speedo for tire size?

 

I have a couple ways to do it. I have it dialed in on my scangauge 2 which has the ability. I also have a hypertech speedo calibrater that corrects it as well. It's nice because it corrects the OEM MPG display as well. I've double checked it with math.

 

So here's a quick question, im doing 38's on an 11" lift, im stuck between 4.88 or a 5.29 gear change. I do half my driving on the fwy and rest city. Looking for some input from both options

 

488 isn't going to be enough, and truthfully, 529 may not either. If there is an option for 571, that would be ideal for an 11" lift on 38" tires.

 

Finally pulled the trigger on nitro 5.29s, but now I’m on a month+ waiting list for install. Still stoked for them!

 

Local installer?

 

Yep, from a very reputable shop in Issaquah, WA

 

They did mine just fine. Well they did bung up the front drain bung, but they made it right, no charge. New place is WAY nicer.

 

Yeah, they cost a little more but they're very reputable and I got 10% off labor for being a member of a local car community (Avants). Month and a half wait time is excruciating though.

 

I can confirm 83 max speed. 5.29 on 295 70 x 17 so just a tad larger than a 33. I had the KDMax tune done and now that limit is gone. I do not regularly get into the 80s. After the tune I have had it closer to 86 -87 ish with no issues on several occasions, but I do not know the top out. For all I know it could be 88.

 

Can't remember what I said previously, but I did some speedy driving this past week and my truck with 5.29's and 35's tops out at 92. I tried it multiple times. Speedo is calibrated. 2019 TRD Off road, stock tune. It hits 92 and then rev limits. Truck could definitely reach over 100 if it wasn't for that limit.

 

Anyone have a shop they can recommend in Portland to install these gears??

 

I finally had a chance to get everything from ECGS installed. Went with an ARB locker up front. Took around 6 hrs total, so not to bad. Definitely helped that my friend has a lift! Pretty happy with how it drives now. Just need to get through the break in period so I can really see how it does.

 

Very nice, jealous of the garage space.

 

This. The camo moving blanket, toys, lift........ahahhahahaha but mostly the ARB port cover!

 

Nice man. I still have over a month of waiting left before mine will be done at Mule. I'll have to check your rig out sometime once you break it in. I'm up next to Lake Wilderness.

 

It always sucks having to wait. Took almost 2 months for the parts to get to me. I will definitely let you know. I am back behind the new Starbucks.

 

gosh dangit. 190 pages of comments on this has me confused a bit.
What would the consensus think: 5.29 or 4.88's? I hate the gear hunting my truck does here in Colorado.
Here's my setup and where I think I want to go with my truck.
2019 TRD OR DCLB AT w/ pop top camper shell and build out (550 lbs all in) add another 100+ for camping crap when loaded
I'd like to run 32-33" tires and a do a 2" lift at some point. currently running 31.5
I'd like to do aluminum front bumper or half bumper with synthetic line winch, rear swing out bumper (150-200 pounds extra?)
I'm not doing hard hard wheeling, just some high passes, get deep to go camp and get to remote climbing areas without much fuss.

Again, just looking for some thoughts from some of the more experienced crowd.
