Aftermarket sales of medium and heavy-duty trucks are projected to hit $73.9 billion in 2006 following 6.2% growth last year, according to a recent Automotive Aftermarket Industry Association (AAIA) study.
"Following relatively flat growth in 2001 through 2003, when annual increases were less than 1%, medium and heavy-duty aftermarket sales picked up in 2004," say AAIA officials.
"Sales have increased for a variety of different 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 transporting dependency on the trucking industry."
