Installation Guide

When servicing any vehicle be sure to follow all safety procedures. First, make sure that

when lifting the vehicle that you are using the appropriate jack for the weight of the vehicle.

Make sure before going underneath any vehicle that it is properly supported with sturdy jack

stands and on level ground so that the vehicle doesn’t fall or slide off of the jack and onto you. As

with any automotive repair, make sure you have the appropriate tools to do the job so you don’t

damage any parts on the vehicle. There is a list of tools needed included in these instructions.

Safety glasses and mechanic gloves should also be worn for your protection.

Be sure to follow the instructions in the order that they are given. The instructions are in a

certain order for a reason and improper installation could lead to damage to your vehicle or the

parts. Keep in mind that if you damage the parts during installation you will be responsible for

the replacement parts.

Take precaution not to exceed the Gross Vehicle Weight Rating (GVWR), or the maximum

load recommended by the manufacturer. It is important that all vehicle's Owner Manuals

recommendations are followed for your own safety and to prevent damage to the vehicle.

Once you are ready to disable the ride light, you will need to disconnect the ground battery

cable (-) to prevent electrical shock/malfunction.

If you have any questions or concerns about the install of your conversion kit, please give your

salesperson a call at 866-597-2397.
