• Secure the rails to the truck bed by installing two clamp assemblies per rail. Slide the Clamp Grip onto the
Clamp Extension toward the Shim Bracket (FIG 9A and 9B). Then, assemble the rest of the clamp parts
as shown below (FIG 9D).
• In order to provide the best support for the rail, shims have been included to fill voids in the bed
construction. Peel the backing from the adhesive and place the 1/8" Black Shim behind the Rail Shim
Bracket between the double wall of the Metal Bed Rail. Next, peel and stick the 1/16" White Shim
between the Black Shim and the Plastic Bed Rail Cap. (Fig. 9D)
• Now tighten your clamp bolts with your Torque Wrench to 70 in-lb (5.9 ft-lb). Finally, check for proper
spacing by measuring between the rails by attempting to insert the BR Gauge in between the rail metal
and the handle stop (FIG 9E). You can also check the measurement between the rail at the canister and
the tailgate end of the rails. The measurements should be equal to or less than those in Figure 9C. The
Clamp Extensions have been pre-installed with brackets and shims to achieve the proper Between the Rail
dimension (BR) when placed on an average factory truck bed. However, not all truck beds are average
dimensionally and some have optional plastic caps or over the rail spray-in liners.
