Strong, Superior AR
450
The stronger the steel, the greater its resistance to dents
and cuts. Here's how that applies to the 
RockStar
Plus. Resistance to dents is measured in yield strength and resistance to
cuts is measured in Brinell hardness. AR450 steel combines the highest yield
and tensile strength that steel technology can provide: 32-percent greater
yield strength and 36-percent greater tensile strength than AR400 steel. Compared
to T-1 steel, AR450 provides 87-percent greater yield strength and 106- percent
greater tensile strength. AR450 is used in all Clement RockStar Plus body
panels, including the headboard and tailgate. Measured against the hi-tensile
steel used by some manufacturers in their headboards and tailgates, AR450
provides 240-percent greater yield strength.
Wear superiority from
AR 450
The harder the steel, the greater its wear life.
that
can be provided. AR450 is 25-percent harder than AR400 and 138-percent harder
than hi-tensile steel. This translates into increased trailer life for Clement's
RockStar Plus. AR450 is so hard that it will stand up under this comparison:
Compare the 5/16-inch AR400 used by some manufacturers in the last 8 feet of
their trailer bodies against the 1/4- inch AR450 used by Clement for all body
panels. Clement's AR450 steel far exceeds the wear life of the competition's
AR400. 
The
RockStar Plus’ standard air-lift gate has an 81-inch opening which is larger
than competitive trailers and improves discharge. Mud flaps are attached to
the tailgate to reduce flap damage. 
Clement’s
exclusive combination king pin plate allows for fast and easy conversion to
either a break-away or a non break-away cylinder shaft to suit individual
requirements. With our inverted cylinder there's no dog-house interfering
with the load. And since the kingpin is located forward, the bridge length
is longer allowing greater gross weights. 
Proven
on hundreds of thousands of trailers, 25,000 lb. axles feature common inner
and outer bearings. Combined with parallel spindle, both axle and bearing
life are substantially increased. With hub-piloted wheels, maintenance time
and costs are reduced. And 50,000 lb center point suspension provides maximum
stability for either off or on road conditions.

The
RockStar Plus comes standard without longitudinals, thereby reducing trailer
weight by 333 pounds for larger payloads without sacrificing trailer strength.
