Mac Trailer has incorporated “cushion ride” as a standard feature on all aluminum frameless and frame-type dump trailers to ensure a quiet contact between the body itself and rails of the chassis.
The “cushion ride” is a product improvement that provides ¾" of an SBR rubber UV-stablized material affixed to the underside of each crossmember to ensure uniformity and security of the bumper protection throughout the length of the trailer.
