INSTALLTION ALERT
General Motors has made changes to their late model 2010 and 20 12 Chevrolet Silverado and
GMC Sierra Light Duty and Heavy Duty Trucks and these changes affect the installation of our
Side Bars.
Currently, all Side Bars manufactured for GM trucks use the factory body mount bolts to attach
the bars and brackets to the truck. In years past, GM used a fixed nut that was welded in place to
the chassis of the truck. Starting late 2010, GM has now gone to a loose nut that is surrounded by
a "Cage Nut" which has two tabs on either side of the nut to keep it from loosening. Along with
this cage nut, GM is also using Heavy Duty Loc-tite on the Body Mount Bolts for added
protection.
Due to this change, Aries is recommending EXTREME CARE when removing the factory body
mount bolts from these trucks. Loosen and re-tighten all body mount bolts by hand! DO NOT
use Impact Tools of any kind! If bolts become increasingly tight as you are loosening them you
may need to retighten & loosen the bolt several times to clear the loc-tite from the threads Failure
to follow this instruction could cause the body mount bolts to seize and the tabs of the 'Cage Nut'
to bend allowing the nut to spin freely inside Chassis floor board!
Most of clients have been installing the existing side bar applications on these new trucks with no
issues, but please be sure to follow our recommendation to prevent any installation issues. If you
have any questions, please feel free to call our Customer Service Department at 888-800-2743.
