Allison Genuine Parts™

Allison Genuine Parts™ are engineered specifically for your Allison transmission using state-of-the-art technology unique to our company. Non-genuine manufacturers attempt to reverse-engineer Allison parts—meaning they are designed without our standards, specifications, manufacturing processes and expertise. Inferior parts can lead to downtime, unnecessary costs and premature breakdowns.

From electronic control modules, to filters to overhaul kits, to sensors, we have all the Allison Genuine Parts™ you need, and we have the expertise to guide you through the process and identify the parts you need.
