The LongArm Height Extension takes your LongArm truck bed extender to the next level. It securely attaches to the LongArm when it’s in the vertical position and easily adjusts to match the height of your cab’s roof rack. The 75 Kg capacity allows for a couple of kayaks or ladders to go up high on your truck, leaving room in your truck bed for other gear, and the included anchor strap tie downs ensure the load is secure.
