PROCEDURE:
1. REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ

2. Starting on the driver side, remove the factory front body mount bolt from the underside of the
cab, (Figure 1). NOTE: The factory body mount bolts need to be driven out of and back into
the steel washer molded into the rubber bushing. Take precautions to avoid damage to the
threads on the bolt or the washer and bushing, (Figure 2).
3. Locate the driver side front Mounting Bracket and bolt it to the vehicle using the factory body
mount bolt, (Figure 3). NOTE: Brackets mount over bushings. Do not tighten at this time.
4. Select the driver side Front Support Bracket and insert (1) 12mm x 120mm Hex Bolt with (1)
12mm Flat Washer through the mounting slot. Place (2) 14mm x 50mm OD x 4mm Flat
Washers onto the 12mm Hex Bolt between the Support Bracket and the factory body mount,
(Figure 4). Insert the 12mm Hex Bolt up through the holes in the factory body mount and
secure with (1) 12mm Flat Washer, (1) 12mm Lock Washer and (1) 12mm Hex Nut, (Figure

Mounting Bracket. Snug but do not tighten hardware at this time.
8. Carefully position the driver Sidebar up to the Mounting Brackets. Line up the mounting hole in
the Front Support Bracket with the hole in the Front Mounting Bracket, (Figure 9). Use the
