• 5/8", 11/16", 3/4", 15/16", 1-1/8" sockets • Torque wrench
WARNING
• If raising the vehicle to install the anti-sway bar, always support
the vehicle with jack stands at both frame rails or at the rear axle
before working underneath. Ensure that the jack stands are securely
positioned, and are rated at or above the weight of the vehicle.
•The installer must read the instructions and use all bolts and parts
supplied. Use only the parts supplied by ROADMASTER to install
this kit.
• Minor modifications are sometimes necessary due to slight vehicle
variations, even for the same year, make and model.
• Regardless of year, make and model, a wide range of options for
specific applications may or may not interfere with the installation.
It is the installer's responsibility to make certain that equipment is
not damaged once the suspension solution travels through the full
range of motion. Failure to ensure adequate clearance could result
in non-warranty property damage, personal injury or even death.
Failure to follow these instructions
can result in property damage, per-
sonal injury or even death.
• 1/4", 1/2" sharp drill bits
• If running changes were made by the manufacturer after this kit
was designed, there may be weldments, braces, gussets, or other
structural items which interfere with the installation. It is the in-
staller's responsibility to allow for these running changes without
sacrificing the structural integrity of the anti-sway bar. Failure to
securely fasten the anti-sway bar could result in property damage,
personal injury or even death.
•ROADMASTER will not be responsible for any damage or injury
resulting from any modification or alteration.
• Check ALL the fasteners for tightness before and after road testing
the vehicle.
• Do not use this document for custom fabrication, as it may not
show all parts or structural components.
• Do not use an air impact wrench when re-installing bolts, as stripped
threads may result.
• This anti-sway bar is only warranteed for the original installation.
Installing a used anti-sway bar on another vehicle is not recom-
mended and will void the warranty.
