PRE-INSTALLATION NOTES (REVIEW ALL OTHER INCLUDED INSTALLATION GUIDES

BEFORE BEGINNING)

• If you’re installing a rear window protection accessory, mount it prior to mounting the cover
• Some models require bulkhead preparation first. Please refer to the instructions in the bulkhead prep kit prior to mounting the cover.
• If your cover includes shims, ax the included bed rail shims first and reference their included instructions.

PREPARE CARGO BED & MOUNT PANELS

1. Remove the plastic cap from the tailgate end of the driver-side track by pressing its tab. Plastic cap will not be reused with your cover installed.

2. Use a T30 Torx wrench to remove the factory bolt near the tailgate end of the track

   • Penetrating oil may be helpful to remove these bolts.
     

3. Slide the driver-side lock-rod striker bracket into the track until its forward hole aligns with the factory bolt. Reinsert the factory bolt and retighten it with the Torx wrench.

4. Repeat steps 1–3 on the passenger side.

5. Place the center panel across the 5 bed, cheated toward the tailgate.

   • Each panel is tapered front to back. Make sure the arrow on the underside of the panel is pointed toward the tailgate.
     

6. Attach the tail panel by holding it at a 90° angle from the bed rails and mate the driver’s side hinge first, followed by the passenger side’s c-shaped hinge.
   

7. In the same way, attach the cab panel but start by mating the passenger side first. Make sure the safety catch has been untaped and then lower panel into position.

8. Position the cover front to back so that the front of the cab panel lines up with the outside edge of the center of the bulkhead. Center the cover side-toside on the truck.
   
   POSITIONING CLAMPS

9. Position the cap clamps as far apart as possible under the center panel. Attach the center panel by 9 uniformly tightening a cap clamp using a 9/16″ socket to between 5-6 ft-lbs.
   

   • While tightening clamps, be aware of possible bed rail cap deformation. Overtightening clamps will damage bed rail caps and cause leaking.
   • Retighten after a week of use. Check them every time you haul on top.
   • The bottom halves of the cap clamps should be in the track system.
     ADJUST THE LOCK RODS

10. Unbolt and move one of the bolts of the lock-rod guide brackets to the second, unoccupied slot using a 7/16” socket. Repeat this on each of the cover’s four brackets.

11. Loosen the set screws for the tail panel lock rods with the provided hex key and retighten each lock rod after ensuring three things..
    
    CORRECT ORIENTATION
    

12. The Z bend orientation is always maintained
    

13. With the lock handle in the closed position, the lock rods are fully under the striker brackets and engaged as much as possible. Ensure the lock handle fully closes.
    

14. With the lock handle in the open position, the rod tips just clear the striker brackets.
    

15. After properly aligning the lock rods in the closed position, it is time to tighten all brackets using a 7/16″ socket. To ensure a tight seal, it is crucial to simultaneously push up on the bracket AND apply downward pressure on the cover. Repeat for all bracket locations.
    

    • The panels may be tough to open and close at first. Leave the panels closed as much as possible to allow the weatherstrip to break in. After a few days, you’ll find things working smoothly.
    • The cab panel has a safety spring lock handle ensuring you engage the lock rods when closing the panel. This helpsprevent accidental opening of the panel while driving.
    • If you are installing a Cross Bin, do so now. Refer to the Cross Bin Installation Guide for details.

16. Repeat steps 11 and 12 for the cab-panel lock rods, but use the inside of the tracks instead of the bends in the striker brackets.

17. The Z bend orientation is always maintained
    

18. With the lock handle in the closed position, be sure the lock rods land inside the track and are engaged as far as possible.
    

19. With the lock handle in the open position, ensure the rod tips clear the track.
    
    ATTACH THE GAS SPRINGS & SAFETY CATCH

20. Open the cab panel. Have a 2nd person support it in the open position. Loop the end of the cable tethers around the ball stud arms, making sure to go beyond the ball stud and nut.
    

21. Attach 2 gas springs to the cab panel.
    Make sure the barrel end is up. If you install your gas springs upside down, they’ll fail
    

22. Attach the safety catch by pulling down on the panel and pushing the keyhole at the bottom of the safety catch around the nut, making sure to engage the spring clip.

    • With the safety catch in place, your cab panel will only open partially. To fully open the panel, pull down on panel while using your other hand to push up on the flat part of the catch until it disengages

23. Attach the 2 remaining gas springs on the tail panel, again making sure the barrel end is up. 17

24. Leave the cover closed and locked for 24 hours to allow the pressure-sensitive weatherstrip adhesive to fully cure.
