How to Install Putco Boss Locker Side Bed Rails on your Dodge Ram

Please note: You must follow these instructions to install the parts correctly otherwise damage may occur.

Read all instructions before installation and check to see if all parts listed are included.

1. Pre‐installation preparation.

Verify the kit contents (check against parts listing). Remove the protective wrapping from the castings, tubes, and bolt kit.

2. Assemble the Locker casting with all bolts and gaskets.

Install the Allen head bolt through the hole in the SSR Locker casting, plastic gasket, and rubber expander. Screw the threaded back plate onto the bolt and snugly tighten the plate against the rubber expander.​

3. Install SSR Locker casting and tubes.

Insert the back plate and rubber expander into the stake pocket hole until the black gasket sits on top of the truck bed. Place an oring on the end of the casting and slide a tube over the casting. Slide a standard casting (with an o‐ring installed) in the opposite end of the tube. Install a casting in the front stake pocket hole. Note: Pre‐2007 Toyota Tundra trucks require spacers to be placed under the plastic cap at the rear stake pocket holes (two per side).

4. Complete rail casting and tube installation.

Tighten each Allen headed bolt (front and rear castings). Continue tightening the bolts until the rail is securely attached to the truck bed.

Putco recommends applying a high quality automotive wax to maintain the original appearance, help prevent water spotting, and protect against weathering on your new locker side rails.
