This research study covers the class 4-8 starters and alternators aftermarket in terms of volume and value across the United States and Canada. It discusses unit shipments, revenue, average price, and distribution channel share. It also analyzes major participants separately for medium- and heavy-duty vehicles. The base year for the analysis is 2019 and the forecast period is from 2020 to 2026.

The overall starters and alternators aftermarket is broadly classified into medium- and heavy-duty vehicle segments. These segments are further classified under new and remanufactured product types.

The demand for starters and alternators in the aftermarket is expected to grow in terms of unit shipments in the coming years. Increase in vehicles in operation (VIO), coupled with incremental miles traveled by the vehicles and the penetration of electronics in medium- and heavy-duty vehicles will drive unit shipments during the forecast period. With the increase in average price per unit, revenues are expected to grow at a faster rate than the rise in unit shipments.
