Truck aftermarket sales on an upward path

Medium- and heavy-duty truck aftermarket sales rose 6.2% in 2005 and are forecast to continue a three-year growth trend, reaching $73.9 billion in 2006, according to a new study by the Automotive Aftermarket Industry Association (AAIA) and the Heavy Duty Distribution Association (HDDA).

After relatively flat growth in 2001-03, when annual increases were less than 1%, medium- and heavy-duty aftermarket sales picked up in 2004. Sales have climbed for reasons including rising Class 4-8 vehicle sales, increases in the average number of miles driven, 2.5% growth in truck registrations since 2000, and the nation's dependency on trucking.
