The 5.29 Mega Thread!!

I am running a KD tune..

 

Thanks for sharing your experience with the tune so far @plasticsnaks! Glad its working out for you and cant wait to do the same.

 

How you like/dislike so far about it?

 

No complaints - the power is there and it's been really smooth. Came from ov's sfob 2.0.

 

I had my tuner pull 10% throttle sensitivity out of it and it's absolutely perfect. Made a huge difference. The truck was almost undrivrable in stop and go traffic. Now it feels normal

 

Good to hear! I too was on ovt 2.0 before and although it was much improved over stock tune, KDMax enhanced it from there. Could not agree more, thanks for sharing your experience and glad its going well for you.

 

I run my own tune.

 

Good deal, it sure beats the stock tune.

 

I’m looking to get my new 2021 SR 4x4 tuned once I get my tires and lift. Who does this in Arkansas?

 

Pm sent.

 

Currently running 32's on a 3" lift. Scheduled for 5.29 install. I may go 33's with next tire change but would likely need to invest in some more lift. I plan on getting a small camper <16ft at some point and want my gear selection to improve towing on the highway as well. Didn't see much in the thread regarding two things that I need to work out before my installation in a couple weeks.
1. How will 5.29 affect towing with my current setup?
2. Yukon vs Nitro? The installer says the Nitro 5.29 are noisy AF. Any truth to that?

 

If you have street tires, stock muffler, and don't listen to the radio, yeah, theyre noisy. Done correctly the noise is minimal that you really have to listen for.

 

I can vouch for this. I have M/T tires but pretty quiet. With my radio off and rear slider open on a quiet street I can vaguely hear a slight whine around 40-50 mph on decel. I quit listening long ago. No worries.

 

Ordered my gears from East Coast Gear Supply about 2 weeks ago. Actually ordered the complete clamshell and rear diff. When I asked them What Brand of gears they'll be using they said from here on out they are using Yukon. Guess they've had too many issues and complaints with the Nitro's. I run 285 Dura-Tracs and I pull a 22' travel trailer (4500-4600lbs.) They should be here any day but I have a Mother's Day camping trip planned so I'll have to wait until I get back to install them. Won't have enough time to break them in before we go. Good thing is, the Pass that we will be traveling over is one we frequent so it'll be nice to have a fresh pull before the gears and I'll be able to compare stock to 5.29's with in a short time to really feel and know the difference.

 

I have Nitro 5.29 gears and after reading about everyone having better luck with Yukon being quiet, I really wish I went that route. Mine are noisy on decel and light throttle from 35-45mph and 65-75 mph. That being said it I love how it drives. I'm on 33's and have it paired to KDMax 6.0 Tune. Was on OV tune which worked well too but this new one by @PapaRee is a dream to drive compared to stock gears/tune.

 

Zuk did my gears. Nitro 5.29 cryo treated. The only noise you can possibly hear from them is coast above 70mph. That’s it. Nothing else from them.

 

Paparee made my current tune and is dialing me in for when the gears are in. He is magical.

 

Just a heads up. I’m running Yukon’s and have the same noises you’re describing.

 

Were your gears REM polished as well? Thought about getting my gears cryo treated as well but Zuk said it wasn't necessary.

 

I have a different tune but if my truck weighed any less, I'm not sure I'd like having my performance tune on. 4LO is touchy and I'm 1000lbs over stock. That being said, thank you for the spacers!
