Larry from Rock River Offroad recently contacted me and asked if I was interested in conducting a review of their recently released Strongbox. The Strongbox extends your existing rear cubby compartment my cutting out the existing cubby and bolting in the new one. I agreed to do the review and he sent me one of the Strongboxes with optional tray. So here is my unbiased review of the Strongbox.
It arrived via FedEx about a week later from Arkansas. The unit was wrapped up with a cardboard box and used bubble wrap to protect the corners. Unfortunately the bubble wrap did little to protect the corners of the 40lb box and tray. While the corners are easy to straighten out it still needs to be better protected for shipping. The unit I received did not come with any hardware, template, or gasket. It is my understanding that subsequent units will be shipped with these items.
I used alcohol to clean up the metal and painted it with Rustoleum Bed Liner Spray. They offer a powder coat option but I think it would be very difficult to ship and install it without damaging the powder coat.
Cut Carpet here.
I made a 24"x11-3/4" template out of cardboard. There are two ridges on the forward edge of the cubby that I used to evenly align the template with laterally.
In order to align longitudinally I drilled a hole 1-1/2” forward of the cubby door tab within the lateral parameters of the ridges.
Then take a look from under the cubby to ensure that you are at the edge of cubby compartment pinch seam.
I don’t have the pull tab anymore so your measure meant might be a little bit more forward of the seam but that’s ok because after the rough cut you will clean it up with a flap disk later. Now you can trace the template using those points of reference. Use caution to what’s on the underside and cut out the cubby compartment. I then used a mallet and 2x4 to straighten out all the curved sides of the floor where the cubby used to be. You can then reapply the template and mark what needs to be cut again. Test fit cubby and grind/flap disk anywhere that needs it until the cubby slides down and sits flush in the tub.
Ensure the Strongbox has cleared all components. I then used a ¼” drill bit and drilled all holes needed for mounting hardware. Special attention is need to the aft side of the box because the mounting holes need to be offset forward enough so that the washer and nut can fit in between the Strongbox and the jack compartment. I used nutserts on the forward side and washers and nuts everywhere else. Now that the Strongbox fits in the cut out and all holes and nutserts are in place you can primer all bare metal. I used rubber weather stripping from Lowes to seal the box. I then fastened all hardware starting with the nutserts, being especially careful not to cross thread them.
