The 5.29 Mega Thread!!

WA has some steep trails and I’m mostly in 4lo the whole way. There is a steep hill climb where I had to floor it in 1st in 4lo with 285s and it struggled going up. With 35s and 5.29s it climbed right up, with maybe only using 60% throttle on the harder, rockier line. I was very impressed with the amount of torque it put down.

additionally going down steep hills made it very easy to control, almost like a crawl gear.

 

Another question. I am 400 miles into the break in and I can tell that the transmission is jumpy now. I guess from trying to figure out what gear to be in. It wasn’t great in traffic either really jumpy there. My question is if the transmission will adjust or if I need a tune to go alone with it?

 

Installed 5.29 on my 22 TRDOR DCLB. Running 33” tires, aftermarket front and rear bumpers,winch,2”lift,Icon RCX leaf pack, softopper and bed rack.I’m estimating I have added maybe 4 or 5 hundred pounds of extra weight to vehicle. Occasionally I tow a 1400 lb off road tear drop.
5.29 gears have made a world changing difference in overall performance.

 

Great to hear. Manual or auto? Thanks

 

Auto. Unfortunately Toyota doesn’t produce the DCLB with a manual.

 

Ya learn something new everyday

 

I'm considering doing 5.29 in my TRD OR DCLB to prepare for a 1200lb camper and overlanding. What are the trade-offs or major downsides to making this change?

 

No trade offs or down sides for me. Overall performance has drastically improved.

 

Same. Drove cross country on 35s and 5.29s twice. 6400 miles round trip each time. Zero complaints

 

What was your speed like on the highways? Could you cruise at 80?

 

You better install a trans cooler if you're gonna drive 80

 

70-80mph the whole way while towing a trailer.

 

With a change this significant to the design of a truck there have got to be trade-offs involved...otherwise I have to wonder like many others have, why Toyota isn't isn't just doing a different rear end at the factory?

 

The diff gears, just like having 2 OD gears, are all meant to maximize MPG. 5.29s give you useable power in 5th and 6th so they're better for more than just downhill on the freeway.

 

So...the "trade off" is giving up on going 90mph on the freeway?

 

After all your 5.29 gear swap, is anyone getting a whine/howl from the rear diff?

I started noticing it when feathering the gas from 60mph to like 40 mph. Anyone?

 

Hell na man you can still do that. what I'm saying is 75 runs about 2500rpm which is in the range where you can actually cruise in 6th without downshifting. I definitely still run 100 every now and then which is probably more like 110 since my speedo hasn't been corrected for 33s

 

Nope. I literally drove 90+mph from Albuquerque NM to Colorado Springs on 5.29's and 35's. 5 hours straight and no issues. My MPG's tanked to 11 though.

 

You can still do 90 pretty comfortable. The rpm is higher but nothing crazy. The only thing that worries me is the speed The drive shaft is going

 

Normal, ignore it.

really want to hear it rip? open your rear sliding window...and start rockin!
