Part 3 - Clamps & Truck Installation

4.1 Base Clamp Assembly

Take a modular clamp (Item 7) and thread a 3/8”-16

1.

hex head cap screw (Item 18) through the bottom

as shown. (See note about Loc-Tite)

Now take a C channel clamp foot (Item 19) and

2.

place it on top of the 3/8” hex head cap screw as

shown.

Repeat steps one and two for the remaining seven

3.

clamps.

Step 4

Step 5

4.1.1 Note: Clamp feet must be used to ensure proper clamping 

force distribution between the rack and the truck bed and 

prevent damage

5.1 Front Upright and Base Clamp Assembly

Now take the rounded shims (Item 8) and place

1.

them on the sidewalls of you truck approximately

where the uprights will sit.

The front uprights will be directly behind the rear win-

dow. Place the unit as far forward as possible

Place the front uprights on top of the rounded

2.

shims (Item 8) making sure that the rubber shims

are completely under the bases.

With one pair of uprights now on the truck, they

3.

must be secured using two Modular Clamps (Step

4). When positioning the clamps make sure they

are 

spaced as far apart as possible.

First torque the clamps on either side of the rack

4.

towards the cab, then follow with the other two

clamps towards the rear of the truck

Torque down the HHCS to 14 lb-ft using a 9/16”

5.

socket and a torque wrench.

5.2 Rear Upright and Base Clamp Assembly

The rear uprights should sit as far towards the tailgate 

as possible without the base hanging off the back of 

the bed rail, while maximizing the distance between the 

clamps (Figure 5.2)

Place the rear uprights on top of the rounded shims

6.

(Item 8) making sure that the rubber shims are

completely under the bases.

With the second pair of uprights now on the truck

7.

they must be secured using two of the previously

assembled (Step 4) clamps (2 per upright). When

positioning the clamps make sure they are 

spaced

at least 7 5/16 inches apart. Any less of a distance

will reduce the load capacity of the rack. You may

adjust the position of the rack on the bed to ensure

that this distance can be achieved

Repeat Steps 3-5 on the rear rack.

8.

Finally with the uprights secured you now want to

9.

take a measuring tape and center your crossbars.

Once centered use your 7/32” Allen Wrench (or

7/32” Allen Drive Bit) to fully secure your crossbars.

Torque the BHCS to 27 ft-lbs.

that you apply Loc-Tite 

(red) to any thread that is 

engaged with the clamp. 

         4.1.3 HHCS (Item 18) 

should be re-torqued every 
5000 miles.
