Tuff Country recommends a 33”x12.50” tire package
once part # 54910 has been installed. If larger than
a 33”x12.50” tire is installed on your vehicle in conjunction with part # 54910; Tuff Country assumes no
liability and the warranty will be VOID. Due to different
types of tread patterns, some aggressive tires in this
size recommendation may require slight trimming of
inner fender plastic.
New longer rear shocks are highly recommended once
part # 54910 has been installed on your vehicle and
the rear shocks need to be ordered as a separate part
#. If you have not already ordered your rear shocks,
please feel free to contact Tuff Country or your local
Tuff Country dealer and order your rear shocks. Tuff
Country recommends installing a 26” fully extended
shock in the rear.
Before installation begins, Tuff Country EZ-Ride
Suspension highly recommends that the installer
performs a test drive on the vehicle. During the test
drive, check to see if there are any uncommon sounds
or vibrations. If uncommon sounds or vibrations
occur on the test drive, uncommon sounds or vibrations will be enhanced once the suspension system
has been installed. Tuff Country EZ-Ride Suspension
highly recommends notifying the customer prior to
installation to inform the customer of these issues if
they exist.
This Suspension kit comes with (1) installation manual
and some post installation procedure literature and it
is the installers responsibility to make sure that the
customer receives the post installation procedure
literature. If a customer would like a copy of the installation manual, please have them visit our website at
www.tuffcountry.com. Have them go to the customer
care section to download these instructions. If you
have any questions, please feel free to call us at (801)
