PRE-INSTALLATION NOTES

For technical assistance call: 909-597-7800 or e-mail: info@fabtechmotorsports.com
READ THIS BEFORE YOU BEGIN INSTALLATION –
Check all parts to the parts list above before beginning installation. If any parts are missing contact Fabtech at 909-597-7800 and a replacement part will be sent to you immediately.
Read all instructions thoroughly from start to finish before beginning the installation. If these instructions are not properly followed severe frame, driveline and / or suspension damage may occur.
Check your local city and state laws prior to the installation of this system for legality. Do not install if not legal in your area.
Prior to the installation of this suspension system perform a front end alignment and record. Do not install this system if the vehicle alignment is not within factory specifications. Check for frame and suspension damage prior to installation.
The installation of this suspension system should be performed by two professional mechanics.
This suspension must be installed with Fabtech shock absorbers.
Use the provided thread locking compound on all hardware.
WARNING- Installation of this system will alter the center of gravity of the vehicle and may increase roll over as compared to stock.
Vehicles that receive oversized tires should check ball joints, uniballs, tie rods ends, pitman arm and idler arm every 25005000 miles for wear and replace as needed.
Verify differential fluid is at manufactures recommended level prior to kit installation. Installation of the kit will reposition the differential and the fill plug hole may be in a different position. (For example, if the manufacture recommends 3 quarts of fluid, make sure the diff has 3 quarts of fluid). Check your specific manual for correct amount of fluid.
