BUILT FROM EXPERIENCE,
NOT JUST A CATALOGUE
A1 Heavy Duty Truck Parts was founded by Aarshvir Sidhu after years spent around heavy duty repair and seeing firsthand how expensive parts, repeat failures, and unnecessary downtime affect mechanics, fleets, and owner operators.
That experience led to a simple idea: study the components we use every day, understand where they commonly fail, and look for practical ways to deliver dependable parts at a more affordable price.
Today, A1 combines stocked inventory, sourcing, direct distribution, and selected A1 developed components with one goal: help customers spend smarter and keep trucks moving.
