Allison original accessories are special parts designed for Allison transmissions and are manufactured using our company's unique advanced technology. Non-original parts manufacturers attempt to reverse engineer Allison parts, meaning they are not designed to our standards, specifications, manufacturing processes, and expertise. Poor quality parts can cause downtime, unnecessary costs and early scrap. Non-original parts cannot meet Allison's standards and specifications, which may cause installation problems and damage to related parts later. Non-original parts cannot have the same quality, reliability and superb technology as Allison original parts.
