Yukkon 5.29 gear on TRD pro 2019 tacoma

I am currently Regearing my truck to yukkon 5.29 gears and I currently have an OV Tune on it. What is my safe top speed during the first 500 miles?

 

Speed isn't the thing to watch. Excessive load and heat is. Best practice is to drive short stints with stops for cool down since the new gears and setup generates higher heat until broken in.

 

I'm surprised that Yukon don't provide any guidance but in the absence of that I'd follow the ECGS guidance for new gear break in:

Yes do this. I have a set of Yukons and this worked for me

 

Did you get the REM coating?
