Product Warranty & Warnings
Fabtech provides a Limited Lifetime Warranty to the original retail purchaser
who owns the vehicle, on which the product was originally installed, for
defects in workmanship and materials.
The Limited Lifetime Warranty excludes the following Fabtech items; bushings,
bump
stops, ball joints, Uniball bearings, tie rod ends, limiting straps, cross
shafts, heim joints, and driveshafts. These parts are subject to wear and are
not considered defective when worn. They are warranted for 60 days from the
date of purchase for defects in workmanship.
Dirt Logic take-apart shocks are considered serviceable shocks with a 1-year
warranty against any manufacturer’s defects. If a shock fails within the
initial year of ownership, the owner must ship the shock to Fabtech for
inspection and service. If after examination the shock is determined to have
failed due to neglect, damage caused by improper installation, or any reason
other than “normal wear and tear,” the owner of the shock will be responsible
for all service costs. Costs include labor, parts, and shipping. Service seal
kits are available separately for future maintenance. All other shocks are
covered under our Limited Lifetime Warranty.
Fabtech does not warrant any product for finish, alterations, modifications,
and/or installation contrary to Fabtech’s instructions. Alterations to the
finish of the parts including but not limited to painting, powder coating,
plating, and/or welding will void all warranties. Some finish damage may occur
to parts during shipping, which is considered normal and is not covered under
warranty.
Fabtech products are not designed nor intended to be installed on vehicles
used in race applications or for racing purposes or for similar activities.
This warranty does not include coverage for police, taxi, first responder
vehicles, race vehicles, or vehicles used for government, commercial, or fleet
purposes. Also excluded from this warranty are sales outside of the United
States of America.
Installation of most suspension products will raise the center of gravity of
the vehicle and will cause the vehicle to handle differently than stock. It
may increase the vehicle’s susceptibility to a rollover, on-road and off-road,
at all speeds. Extreme care should be taken to operate
the vehicle safely at all times to prevent rollover or loss of control
resulting in serious injury or death.
Oversized tires and wheels may decrease the vehicle’s braking capacity.
Drivers should always brake early and be aware of the increased stopping
distance of the vehicle. Drivers should adjust their driving habits to the
effectiveness of the braking. Adjust your driving habits to these changes.
Failure to drive safely may result in serious injury or death to the driver
and passengers. Driver and passengers must ALWAYS wear their seat belts, avoid
quick sharp turns and other sudden maneuvers.
