The 5.29 Mega Thread!!

Man. I’m stoked for this.

 

With 5.29's the trucks ECU cuts off the speed to somewhere around 85/86 mph from what I've found in my research. 4.88's would allow a higher top speed but no clue what the cut off changes to. The next OVtune update being released, the 2.0 tune, is going to eliminate that. Not sure where the cut off will be with ovtune after since hes only given the beta with the gearing settings changed out to a few people to test so far and it was strictly to see if he successfully removed the cut off for people with 5.29's. The standard beta without the gearing settings is available for others.

 

Thanks great information!

 

Thanks for the info guys

 

My friend put 4.88s in his rig with 33s. Unfortunately that didn’t stop the trans from hunting for gears. Needless to say he was pissed and after riding in mine with 5.29s on 33s.
He ended up getting 5.29s.
Living in ATL, you have to drive at speeds on the hwy, or you will get flat out run over.
I am rolling 33 KM2s (heavy as hell) and I got no issues pulling mtn grades now, nor does the driveline feel over geared.
I roll at 70-80 with no issues. At 80 with my size tires the RPMs are just touching 2500, and it keeps that gear up grades.
When I put on 34/35 the RPMs will go down slightly.
I like where the truck keeps the RPMs now.’makes the truck feel more responsive. Before is was just bogging in low RPMs, not I feel like I am in a sweet spot.
On a side note I rode in a friends truck that had the OV tune, but no gears. Was not impressed, as while it did hold gears longer, the truck still felt under geared to me.

 

You will appreciate it. Tacoma still isn’t a speed demon but you will appreciate the response you get when you need it.

 

As far as hunting for gears, most of my driving is on flat ground in SoCal. The truck will still shift between 5-6 periodically, probably more because of my driving style, but it absolutely isn’t “hunting” like it did with stock gearing. The truck will actually hold 5th or 6th when I want to go fast (wanting it to downshift) and it will pull from where it’s at. Pretty cool as it would never do that prior to regear.

 

@Built2Ride I will say that 5.29s with stock tune is fine. 3rd gear has that weird flat spot like usual, but it’s easy to drive. I have been running the 5.29 beta tune with the gears and it is much better. I thought the tune was ok prior to regearing and I felt the changes, but it didn’t fix the truck. Regearing and then driving around on stock 04b31 tune was fine, but regear paired with ovtune is definitely a better driving experience. Again, we all know that this truck has it’s downfalls when it comes to power down low, but the feel is much better with the tune. If I hadn’t already purchased ovtune last year, I’d probably not miss it, but since I’ve got it and can run it, I’ll honestly say I’m glad I have it. I’m active duty and almost out of the door again for deployment (and a full time student) so I don’t get to use the truck off-road, so I can’t comment on its performance there. For those interested in the tune, just find someone who will let you drive their truck and see for yourself!

 

With your friend's 4.88 gears in his truck, did he have OV Tune or was he still on the stock programming?

 

I appreciate your input. It’s good to hear that your experience with the Tune has increased the drive ability. I will also say the new gears made my Offroad experience way better. In low range this thing crawls now, before it felt like it required a lot more effort on my part.

 

It's unfortunate that you made this post and that it received likes, because it confirms how clueless this forum is when it comes to data. Re-gearing a vehicle will impact its ability to accelerate quickly. I am not getting another Tacoma to take it down the track, but acceleration stats would validate how much these trucks need to be re-geared. It's a valuable metric that would substantiate the videos from all the wannabe YouTube bloggers posting about how the truck "feels right" after doing this, while a shop owner is explaining basic gearing concepts for them. And for this forum.

 

Clueless? It was a joke. The reason for his comment and the likes is because the OP crawls his truck, nothing more.

This forum has been nothing but on point. To make a statement such as the one above, really is a waste of your time and ours.

Bring on the Data that you seek, and we will add it in here. If we can understand it is a different story..what do I know I am just a landscaper lol

 

Nailed it.

 

Blew out my rear diff yesterday doing stupid s*** at the park I have an 06 Tacoma prerunner with a 5-speed currently running 33s but my next set of tires are going to be 35 I want to know what RPM I'll be at in 5th gear if I run 5.29

 

There are a couple of online calculators but your rpm is calculated based on your speed. What rpm at what speed are you looking for?

 

Well right now at 70 I do 2100 rpm since I don't have a choice I'm going to regear to 5.29 to accommodate 35" tires I'm just worried since I'm on 33s I'll be at 4000 rpm at 70

 

Assuming a .71 5th gear. 35” tires with 5.29s @ 70mph would be 2524 rpms

 

That’s what I call Data?!

The gears literally saved my ass today bro. I was traversing straight up an incline up to 5600’, which is high on the east coast, but the trail was covered in 9” of powder and f’ing straight up and down some of the longest most puckering moments I have had.
Truck was crawling in low range like a boss...I fact is was so slow, it felt TacoBoxesque, well that what I am going to say until I can get my hands on one.

 

I blew my diff up sending it yesterday now I'm forced to regear before I bought new tires I'm currently running 33" km2 going to a 35" cooper stt pro I'm worried that in the time I'm running 33s I'll be screaming at 3500 rpm at 70 mph

 

Brutha I wish I had a better grip on how the 5.29s will affect you with 33s, as that is what I currently have but I got 3rd gen, so I can’t comment.
However, as the OP pointed out above. You would be at 2500ish RPMs at 70 on 35s. It would be tough for me to think that you would roll up to 3500k on 33s.
But that’s the tricky thing, you don’t have 6th gear so your RPMs will increase more because your rolling in 5th.
