Rough Country 273N2 - Manual

Thank you for choosing Rough Country Off Road Gear for 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
this system without this knowledge may jeopardize the integrity and/or operating safety of the vehicle.
Please read instructions before beginning installation.
PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Offset, as much as possible, what is lost in rollover resis-
tance by increasing tire track width. In other words, go "wide" as you go "tall".
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, lifts, and/or combining body lift with suspension lifts
voids all warranties. Rough Country makes no claims regarding lifting devices and excludes any and all implied claims.
We will not be responsible for any product that is altered.
Braking performance and capability are decreased when significantly larger/heavier tires and wheels are used. Take
this into consideration while driving.
The required installation time for this system is approximately 2 hours (see recommended tool list shown below). This
kit is usually sold as a front end leveling kit, but can be sold in combination with rear blocks and u-bolts or a rear add-a-
leaf. Shocks with longer travel are recommended.
This suspension system was developed using 285x75R16 tire on an 8” wheel. Before installing other combinations,
please consult your local tire and wheel specialist.
If questions exist we will be happy to answer any questions concerning the design, function, and correct use of our
products.
