IMPORTANT ALERT: GM uses a very strong thread-locking compound on all
body bolts. Use of an air assisted impact ratchet can cause damage to the
threads on factory body mount bolts and the internal nut assembly because of
this thread locking compound.
We only recommend the use of hand tools to slowly remove and reinstall body
mount bolts on all GM vehicles.
PROCEDURE:
CRITICAL INFORMATION: If during the removal process, it becomes increasingly
difficult to unscrew the body mount bolt with hand tools, tighten the bolt several
rotations to clear the thread locking compound from the threads, then reverse
direction and continue to unscrew until the body mount bolt is out. Repeat this
process as necessary on all GM body mount bolts. Use of an appropriate antiseize compound is highly recommended for re-installation. Tighten body mount
bolt to factory torque specifications for your particular model year.

PARTS LIST:
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.
