Terrafirma Rear Differential Guard
$150 – $215
The vertical bulge in the front and rear axle cases allows the crown wheel to rotate inside. The crown wheel is a large gear that trasnfers the input drive into the differential and along the axle shafts. The bulge is pressed steel and when rammed into objects such as rocks, can lead to loss of structural integrity and leaking of valuable lubricating oil. These Terrafirma differential guards are easy to fit and offer protection against the hardiest obstacle.
