SOUTHFIELD, Mich. — Industry analyst R.L. Polk and Company has predicted that longer commercial vehicle life-cycles combined with increasing cost of new engines are coupling to increase demand for replacement parts for diesel engines.


The age of Class 3-8 vehicles is increasing and will continue to do so as environmental regulations drive up the price of new engines, R.L. Polk concluded in an analysis on Diesel Engine Parts Replacement, which will increase demand for in-frame kits and turbochargers.


Specifically, the forecaster estimates there will be market demand for 221,000 new in-frame kits by owners of Class 6-8 vehicles over the next 12 months as well as 258,000 replacement turbochargers for Class 3-8 vehicles.


The complete findings also predict demand for seven other diesel engine components including fuel injectors and overhaul kits.


“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.”
