IMPORTANT INFORMATION THAT NEEDS TO BE
READ BEFORE INSTALLATION BEGINS:
 
Tuff Country EZ-Ride Suspension recommends using 
a 4.5” back spacing on the tire and wheel 
combination. The stock wheels will not work in 
combination with the new spindle design. 
 
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. 
 
General Motors has introduced a new transfer case 
option that uses the name “Auto Trac”. Auto Trac is a 
full time 4WD system. This options pertains to the 
Tahoe (2 or 4 door), Suburban and some pick up 
trucks. To identify this, see the transfer case 
selection panel located on the dash board. Below the 
2HI button it will read “Auto 4WD” or “Auto”. 
Vehicles with the “Auto Trac” transfer case may 
encounter a front drive line vibration when the lift kit 
is installed. After installation, if the vehicle that you 
are working on encounters any front driveline 
vibration, the stock driveline may need to be 
replaced. If this is the case on the vehicle that you 
are working on, please feel free to contact Tuff 
Country or your local Tuff Country dealer and order 
part # 10820 to replace your stock driveline. 
 
Tuff Country EZ-Ride Suspension highly 
recommends NOT installing part # 16810 on vehicle’s 
with a two piece rear driveline. If this suspension 
system is installed on vehicle’s with a two piece rear 
drive line, rear drive line problems may occur and 
your Tuff Country WARRANTY WILL BE VOID. 
 
After the completion of the installation a front end 
alignment is required. Also an exhaust modification 
is needed. 
 
New longer front and rear shocks are needed after 
this suspension system has been installed and the 
front and rear shocks need to be ordered as a 
separate part #. If you have not already ordered your 
front and rear shocks, please feel free to contact Tuff 
Country or your local Tuff Country dealer and order 
your front and rear shocks. 
 
If the vehicle that you are installing Part # 16810 was 
manufactured in 1998, you must order an additional 
axle extension kit. The part # that needs to be 
ordered is part # 10806.
