About Us


Matt Ayriss






Let me give you a little history…
Rocky Mountain Powertrain has been in business since October 2008. We are glad you found us! On average, we can save you roughly 20% of what the dealership is charging. We offer a 1 year warranty on all rebuilds fully done by us. We have a Engine and Transmission Dyno test stand to test our components. We are also a service Dealer for Twin Disc, Palmer Johnson Power Systems and Volvo Penta Industrial.

Hi! I’m Matt Ayriss and I’m one of the owners of Rocky Mountain Powertrain, LLC. I personally have more than 20 years of experience both in the shop and in the field. My love for this industry started back when I was a teen working on tractor equipment on a farm. Since then I have worked for a major dealer and other independent repair/service facilities.

Max started with us from Pickens Technical as an intern in the Spring of 2012 and has been with us ever since.  Max currently works on engines, transmissions, and PTO’s.  He is a quick learner and understands how to put out a quality product.



Wes joined the team in fall of 2015 as our building mechanic and delivery driver. Wes tackles building projects and maintenance issues, along with helping keep parts and components moving from vendors to the mechanics. Our indoor engine dyno bay was one of Wes’ first projects and came out excellent.



Kelly started with us in July 2013.  She grew up in Illinois where her father owned his own oil field pump repair business, so she fit right in with Rocky Mountain Powertrain. Kelly does our purchase ordering and keeps on top of all the paperwork.



Loyd joined Rocky Mountain Powertrain in June of 2016.  He has 30 plus years experience with transmission overhauls.  His experience and knowledge make him a great fit for the team.  On weekends you might catch him riding his Harley all over Colorado
