Mack Trucks has redesigned its PartsASIST online parts-ordering platform, delivering a modernized user interface, faster performance, and new tools designed to simplify the parts-purchasing experience for customers and dealers.

First launched in 2021, PartsASIST provides 24/7 access to Genuine Mack Parts, All Makes products, and the Road Choice and DEX Heavy Duty Parts catalogs, serving Mack truck owners through a single online storefront.

The latest update introduces an overhauled user interface and experience built on customer feedback, with improvements across search functionality, product display, order management, and real-time inventory visibility.

“This redesign represents a significant step forward for PartsASIST and for how our customers interact with the Mack parts ecosystem,” said Rich Greenhill, vice president of aftermarket and solutions, Mack Trucks. “We took a hard look at the entire user journey and rebuilt the experience from the ground up – faster load times, cleaner navigation, and a more intuitive layout that helps customers find and order the right part with fewer clicks.”

Key enhancements to the PartsASIST platform include:

• Modernized interface: A clean, contemporary design with improved navigation and responsive layout across desktop and mobile devices.
• 360-degree product views: Enhanced product pages with detailed imagery, specifications, and alternative product suggestions to support confident purchasing decisions.
• Real-time inventory visibility: Live warehouse-level stock availability, enabling customers to verify parts are in stock before placing an order.
• Streamlined order management: A redesigned order-tracking dashboard with enhanced filtering, related-order linking, and simplified request-for-quote workflows.
• Improved search and filtering: Faster search results with expanded vehicle and fleet filtering options, including chassis series, VIN, and unit name lookup.

“Every update we made was driven by how our customers actually use the platform,” said Eric Davila, product owner, eCommerce aftermarket, Mack Trucks. “From the way search results are displayed to how orders are tracked, we focused on removing unnecessary steps and making the day-to-day parts-ordering process as efficient as possible. The goal is a purchasing experience that feels as seamless as working directly with your local dealer.”

The updated platform retains PartsASIST’s core capabilities, including fleet management tools, quick-order functionality, and integration with the Mack dealer network across the U.S. and Canada. Customers can continue to access special pricing, fleet-specific part numbers, and promotional offers through their existing accounts.

“PartsASIST has always been about giving customers an easier way to buy parts,” Greenhill said. “This update takes that promise further – delivering a platform that’s faster, smarter, and built to keep fleets running.”

The redesigned PartsASIST platform is available now at Mack’s website. Mack truck owners and dealers can register for access or log in with existing credentials.
