Yukon Master Installer Certification Program

The Ultimate Drivetrain Certification Program

At Yukon Gear & Axle, we say it’s proper training in differential and drivetrain that gets the job done right.  For over 40 years, Yukon Gear & Axle has been at the forefront of drivetrain product engineering, quality manufacturing, knowledge, and tech support.  Yukon has now partnered with LetzRoll Offroad to create a national drivetrain training academy in Mesa Arizona, offering a three-day course in differential installation mastery.

If interested, please submit the form below for more information.


Master Installer Program Overview

The Yukon Master Installer Certification Program brings together the best installers in the nation.  Those that become certified become leaders in their market and have the backing of Yukon Gear & Axle to support it. It by no means is an easy program, but those who are able to complete it will earn the title of a Master Installer, and join the ranks of 60+ of the best differential technicians in the country.


75% Hands-On | 25% Class

This program combines the technical aspects of the manufacturer along with the skillset and hands-on installation knowledge of the installer. A combination of classroom and technical installation on a number of leading axle assemblies is designed to take a general drivetrain installer to a master drivetrain installer.



Students that successfully complete the course will receive certification as a Yukon Master Installer. Certified installers will receive customized local market programs, shop shirts, in-shop signage, and targeted support to promote your business in your market.  This Master Installer Certification program is the only one in the nation!

Here's what our customers have to say about us



"We do our fair share of differentials and this course was informative and helped a lot. It was a fun experience too." –Klimek, Defiant Motors Inc.

"It was awesome... I had preconceived ideas about how the class would go and what products would be there, but it was different in a good way. It was well-thought-out for people who have been doing differentials for a while. I'm already sharing that we're a Master Installer business and I'm excited to get Yukon's marketing support going now that the class is over." –Art, Geahr Offroad

Information was spot on and built on my current skills. I do a lot of gears and most definitely got tuned up, learned some new ways of doing things, and left a better mechanic.” –Ed, Chicago Driveline




Just an overall great experience. We felt welcome from the start, jumped into sit-down learning then over to hands-on. The tips, tech, new ideas, and better ways of doing things were all great. Multiple diff builds and real experts to work us through questions. Would definitely suggest it to lots of other shops if you want to fine-tune your business.” –Quinn, All J Products

Great class to build on if you have years of experience. This was the real deal in training from tools, to patterns, to multiple diff setups, metallurgy, and customer service. All very well done.” –Arron, Arron’s Olympic 4x4

The class was good. I definitely learned some things that I didn't know before.” –Chris, Carl's Auto Care





I wanted to take a quick minute to thank you again for a job well done. I really enjoyed my time at Letz Roll. The staff there was an awesome crew. The knowledge and stories were great. The freedom to “make yourself at home” during the time at the shop was much appreciated. I really enjoyed harvesting some of your intimate knowledge. I got exactly what I needed out of the class. I wanted the reinforcement from you and the Letz roll staff that what I thought I was reading out of gear patterns was ACTUALLY correct. I'm glad to know that the heating and cooling of parts to make fitment easier is an ok thing to do. I got a few good tool ideas too.

Thanks again, I can’t say enough about the hospitality.
