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. 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.
This 4” suspension system was developed using a 35X12.50X17 tire with 4.5” to 4.75” of back spacing on aftermarket
wheels. Stock wheels can be used with this kit with up to a 35x12.5 tire, but different tire manufactures designs may re-
sult in a tire width that could result in contact with the lower control arm and/or front sway bar link in a sharp turn. Please
consult with your tire and wheel expert before purchasing. Also note that if wider tires are desired, offset wheels will be
required.
If question exist we will be happy to answer any questions concerning the design, function, and correct use of our prod-
ucts by calling 1-800-222-7023.
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.
IMPORTANT NOTES : Upon completing the install of this kit the draglink must be adjusted to center the steering
wheel BEFORE the vehicle is driven. Failure to do so will cause a computer error, odd handling, and poor per-
formance.
On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate
factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission
pan
tearing the factory boot and rubbing on the shaft . Generally this occurs during heavy articulation when
front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper pro-
cedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase
clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed.
Additionally on 2012 Models, additional exhaust modification on the passenger side crossover pipe will
be required for adequate clearance on the front driveshaft.
