Diff covers have a
rough job. They have to protect your large investment of gears and lockers,
while you pulverize them over boulders the size of Volkswagens. They get
no respect. The average diff cover is less than 1/8" thick, with
the heavy duty units being 1/8" thick. There are some companies that
make cute little "diff guards" that can protect your diff cover
from boulders. But why not simply use a thick, bomb proof diff cover and
leave the bolt on gimmicky stuff to the street posuer crowd?

Shop. These guys don't make anything light duty! A look at any of their
rigs, and you know they mean business. So when WMS asked me if I'd like
to test out their new Dana 44 diff cover, I knew this thing would mean
diff cover really is impressive. It's heavy, it's meaty. If you're looking
for light weight, forget about this diff cover! Check out the built in
skid plate on the bottom of the cover. The stock diff cover doesn't even
remotely hold a candle to the WMS cover. Bash this thing all day long,
and it's going to take the abuse! The WMS diff cover is made from a 3/8"
steel shell with a 1/4" ramp.
Installation was pretty
straightforward... Simply unbolt the old diff cover, and bolt on the new
one. The WMS cover came with high quality allen bolts that are countersunk
in the lower skid plate to protect them from rocks. Notice how the new
diff cover slightly hangs below our well-ground Dana 44 pumpkin. A quick
pass of the grinder, or a few passes through Little Sluice should clearance
it just fine.
While I'm VERY impressesed with the finish, and heavy-dutyness of the
WMS cover, I'm afraid the price of this beast isn't as appealing. At $200,
this is the most expensive diff cover I know of. But if you want the best
of the best, and cost and weight isn't a concern for you, then WMS diff
covers are for you.
