R.L. Polk & Co. has released its new Diesel Engine Parts Replacement Analysis, designed to help engine manufacturers and parts suppliers as well as parts distributors in planning inventory strategies.


According to the analysis, owners of commercial vehicles are expected to demand 221,000 new in-frame diesel engine overhaul kits over the next 12 months. In addition, the aftermarket will need 258,000 turbochargers for Class 3-8 vehicles in the coming year.

"The Diesel Engine Parts Replacement analysis helps OEMs and aftermarket customers better prepare for market demand for replacement parts in commercial fleets," said Mark Seng, vice president of sales and client services for Polk. "With more organizations keeping their fleet vehicles in operation longer, this solution will help aftermarket suppliers and OEMs best identify specific inventory needs."

The research, which was also conducted by Commercial Motor Vehicle Consulting, focuses on the demand for nine engine parts, including fuel injectors, turbochargers, full engine replacements and overhaul kits. The companies also analyzed the demand for original equipment versus aftermarket components, as well as salvage parts.

The basis of the study is the development of replacement factors by engine manufacturer, engine part and the vehicle's GVW. These factors are then applied to vehicle populations and can be compiled by vehicle and engine manufacturer, engine size, specific vehicle location and fleet operation.
