Rough Country 699 User Manual
Yj spring over conversion kit
Thank you for choosing Rough Country for your suspension needs.
Please read all the instructions before beginning the installation.
PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend, because of rollover possibility, 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.
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.
NOTICE TO DEALER AND VECHICLE OWNER
Any vehicle equipped with any Rough country product must have the “Warning to Driver” decal installed on the sun visor
or dash. The decal is to act as a constant reminder for whoever is operating the vehicle of its unique handling character-
istics. INSTALLING DEALER—It is your responsibility to install the warning decal and to forward these installation in-
structions on too the vehicle owner for review and to be kept in the vehicle for its service life.
IMPORTANT INSTALLATION NOTES:
This is a spring over kit and will require more components depending on how the vehicle is expected to per-
form. This kit does require welding, therefore it is recommended to have this kit installed by a professional that
is familiar with welding procedures. This kit is designed to move the leaf springs from the bottom of the axle to
the top effectively giving lift to the vehicle and flexibility with the use of the stock springs. A CV type driveshaft
is highly recommended for this application. Aftermarket springs can be used with this kit, but pinion angle will
be affected and may require driveshaft modification or the mandatory use of a CV type driveshaft. Steering will
typically need a s-link system or high steer system to make sure all components are clear. At the least a new
pitman arms is recommended to reattach the steering. Take care not to use excessive heat when welding the
spring perches on the axles. Longer shocks will be required for this kit. We also recommend the use of
stainless steel brake lines.
