30640 YJ 4” LIFT KIT
INSTALLATION INSTRUCTIONS
Warrior recommends this system be installed by a certified technician. In addition to these instructions, professional
knowledge of disassembly and reassembly procedures as well as post installation checks must be known. Attempts to install
this system without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle.
Please read instructions before beginning installation. Check the kit hardware against the parts diagram. Be sure
you have all needed parts and know where they go.
With the installation of all lift kits and larger tires it is important to check the condition of your steering stabilizer. If the
stabilizer is worn or is leaking it should be replaced. Steering stabilizers are designed to restrain “bump steering” and front
end vibration, giving added life to tires, ball joints, and other steering components. A large bore off-road stabilizer kit is
highly recommended for vehicles equipped with larger tires.
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 resistance
by increasing tire track width. In other words, go "wide" as you go "tall". Many sportsmen remove their mud tires after
hunting season and install ones more appropriate for street driving; always use as wide a tire and wheel combination as
possible to enhance vehicle stability.
We strongly recommend, because of rollover possibility, that the vehicle be equipped with a functional roll-bar and cage
system. 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 significantly 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.
Warrior makes no claims regarding lifting devices and excludes any and all implied claims. We will not be responsible 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 products.
