Thank you for choosing Rough Country for all your suspension needs. 

 

Rough Country recommends a certified technician install this system. In addition to these instructions, professional 
knowledge of disassemble/reassembly procedures as well as post installation checks must be known.  Attempts to install

and make sure you have needed tools. 

 

PRODUCT USE INFORMATION 

 

As a general rule, the taller a vehicle is, the easier it will roll. Seat belts and shoulder harnesses should be worn at all 
times. Avoid situations where a side rollover may occur.   

 

Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this 
into consideration while driving. Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height 
over the intended height of the Rough Country product purchased. Mixing component brands is not recommended. 

 

Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re-
sponsible for any product that is altered. 

 

If question exist we will be happy to answer any questions concerning the design, function, and correct use of our prod-
ucts. 

 

This suspension system was developed using a Maximum tire size 

of 

33X12.50 on 8” wheel with 3.75” back spacing. 

Note 

if wider tires are used, offset wheels will be required and/or trimming may be required. 

 
Please note that a variation in the rear block and u-bolts exists for this application.  1986-96 short bed standard 
cab models require part #s 1733BOX1 & 1734BOX1. All other pickup applications require 1733BOX1 & 
1733BOX2. Please verify that the correct box kits are present before beginning the installation process.  If you 
have any question please call technical assistance at 731-285-9000.
