The shock absorber by definition is a hydraulic device used to dampen
suspension/body movement. The road surface irregularities or roughness is
compensated for by the shock absorber. The roadmaster chassis incorporates
the “Bilstein” shock in the design of the exclusive air glide suspension sys-
tem. This shock absorber is a telescopic, monotubed unit filled with nitrogen
gas and hydraulic oil. The result of the mixture is uninterrupted damping for
the smallest of wheel deflections.
By design, a self lubricating seal is used which will allow approximately
10% of the total oil capacity to pass onto the piston rod. The gradual process
of oil loss does not affect the performance of the shock absorber during the
service life. This process will be evident after a long period of service by an
oil film on the body of the shock absorber. The appearance of a coating or
film on the body or rod is completely normal, it is an indication the shock is
functioning normally.
The road holding, handling, balance and braking characteristics all can
be contributed to the shock absorber. The operating conditions for which the
shock absorber must endure will determine the life span. However, since the
only moving part is the piston rod there are no spring or hinge pins to wear
out, get weak or deteriorate.
