PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend that seat belts and shoulder
harnesses should be worn at all times. Avoid situations where a side rollover may occur.
Braking performance and capabilities are decreased when significantly larger/heaver tires and wheels are used. Take
this into consideration while driving. Also, speedometer recalibration is necessary when larger tires are installed.
Do not add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height of
the Rough Country product purchased. Mixing component brands, 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.
The 4.5” Long Arm Kit system was developed for 32x11.50x15 tire on 15 x 8 after market wheel with 3.75” of back spac-
ing. The 6” kit was developed for 33x12.50x15 tire on 15 x 8 after market wheel with 3.75” of back spacing. Due to the
inconsistency of vehicles when manufactured and the various options available, the amount of actual lift gained by this
lift kit will vary. On models outfitted with extra bolt-on equipment and accessories, Rough Country offers new coil spring
isolator pads made from polyurethane to boost ride height 3/4".
Please verify before installation rear axle tube diameter is 2 1/2” or 3”. Both sets are included with this kit to accommo-
date rear axle options of the vehicle.
This kit features Rough Country’s adjustable joint design. Adjustable end tool is included in kit.
Assemble the joints per the separate instruction sheet Part # 92RCJ120 provided
