Range Rover - QT Differential Guards
A few pix of the QT diff guards. The rear is bolt on, but you need to weld on two tabs for the front. Not hard for someone good with a welder. Just be sure to disconnect your battery and alternator... I did, and both still functioned after the job!
The shiny black area is where we welded, then primed the bare metal afterwards.
Now for the easy install... the rear diff "rockslider" guard
The "rockslider" effect of this guard allows you to slide the diff over hard spots without getting hung up on the diff bolts and chewing them up. Also the drain plugs are protected a bit.
Can't see it too well here, but mind the top of the guard and the wires and brake lines. Ensure you cannot pinch these components against the fuel tank upon suspension flexing.
