Before you begin:

EXTENDED CAB BRACES & HARDWARE (EX VERSION ONLY)

Remove all components from the shipping carton.

The rack should be assembled on a padded surface such as carpet to prevent scratching of aluminum surfaces. Remove bands
securing components together.

Read the instructions thoroughly to familiarize yourself with the assembly sequence.

Note that you DO NOT tighten any nuts and bolts until the completed rack is installed on the vehicle unless specified. This allows for
minor adjustments to the rack during the installation process.

Gather the following tools used to assemble and install the rack.

9/16” Socket or open end wrench
3/8” Drill bit and drill
Pencil or marker
Tape measure
Center punch and hammer (optional)
Level (optional)
2 Clamps (optional)
Boards (optional)

1. Connect front and rear sections

Each side rail side contains a front and rear section preassembled for easier assembly. The front and
rear sections are banded together.

Remove the banding and separate the front and rear rail sections from packaging.

On a flat surface, place boards under the front and rear rail sections as shown so that the rear ‘Y’
bracket does not touch the ground. This will make aligning the front and rear rail sections faster.

On the front section (the end with the straight round tube), slide the 5” bracket backwards until the two
back holes on the 5” bracket line up with the two holes on the end of the lower rectangle tube.

Insert the rear rail section into the 5” bracket and line up with two remaining holes.

3. Set middle crossbar assembly in place.

The middle crossbar assembly is the ribbed rectangle extrusion with a slotted bottom with ‘Y’ brackets
attached to each end.

Orientate the crossbar so the ribbed bottom is facing down.

Position the middle crossbar assembly on the front side rails forward of the 5” bracket and about
halfway between the 5” bracket and the next support bracket. The middle crossbar assembly will be
secured in place after the final adjustments on the vehicle.
