PROCEDURE: 
 
1. REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ
INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION.
2. From underside of vehicle, remove the driver side front body mount bolt, steel washer (if
equipped), and rubber bushing, (Figure 1).
3. Select the driver side front Mounting Bracket. Insert the factory body mount bolt through the
Mounting Bracket and into the steel washer, (if equipped), and rubber bushing. Hang the 
Mounting Bracket in position by partially threading the factory body mount bolt up into place, 
(Figure 2). Repeat this step for driver rear Mounting Bracket, (Figure 3). Snug but do not 
tighten hardware at this time. 
NOTE: There are several different designs, (depending on model year), for the factory 
steel body mount bracket. The Sidebar Mounting Brackets can be switched, driver side 
to passenger side, to provide additional clearance between the gusset on the Mounting 
Bracket and the factory steel body mount bracket welded to the frame. The front 
Mounting Brackets however, are not interchangeable with the rear Mounting Brackets. 
To prevent unnecessary noise, adjust the position of the Mounting Brackets so that the 
Brackets do not come in contact with the factory steel body mount bracket. 
4. Carefully position the driver/left Sidebar up to the Mounting Brackets. Attach the Sidebar to the
Mounting Brackets with the included (2) 1/2” x 2” Hex Bolts, (2) 1/2” Lock Washers and (2) 1/2” 
Flat Washers, (Figure 4). Snug but do not tighten hardware at this time. 
5. Level and adjust the Sidebar, check Mounting Brackets for clearance between factory steel
body mount brackets. Once satisfied with fit, tighten all hardware.
6. Do periodic inspections to the installation to make sure that all hardware is secure and tight.
