Just fitted this one to my D4. Went on easily and very happy with the result. My truck is used extensively on and off-road. Had I fitted this a couple of years back it would have protected me from an incident that left the truck lying on it's belly overnight in a forest. I had backed over tree branch that managed to climb up inside and tear out half the wiring loom to my gearbox. This is now out of the line of fire and gives me renewed confidence! Thanks Ben, you do excellent work.
