Remove the trio of factory bolts that run under the bed rail along the 

length of the driver-side cargo bed wall using a T30 Torx wrench.

Repeat steps 1–2 on the passenger side.

PRE-INSTALLATION NOTES: 

It’s possible for one person to install a DiamondBack solo, but the whole 
process, especially positioning the panels and adjusting the lock 
rods, is much easier with two people.

If you are installing a 

cab guard

 or 

headache rack

, you should 

mount it prior to mounting your DiamondBack cover. Refer to its 
installation guide for details.
