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 &
