You will need the '16 shock towers, or to modify the ones you have to clear the extra bracing bits.

People need to:

• Stop over-tightening screws for the diff housing (allows the diff housing/bevel gear to expand and affect gear mesh).

• Stop overfilling their diffs (allows the diff housing/bevel gear to expand and affect gear mesh).

• Stop over-tightening screws for the bulkhead cover using electric screw drivers (allows the diff bulkhead cover to expand and affect gear mesh).

• Replace worn out bulkhead.

• Replace both pinion and bevel gear if already stripped one of the gears.

• Replace shot bearings.

• Stop cranking their slipper down way too hard and instead set their slipper according to grip level (we run 0mm on the spring/loosest setting).

• Stop using the 1/8th buggy method of cranking the throttle to get the car back on its wheels.

Just one of these things will affect gear life…….then add up several of them and you WILL have problems !

Material have been added by Xray to where the bearings sit in the bulkhead and to the bevel gear to prevent the gear mesh to be affected by the above points, BUT there is a limit to what you can do before the responsibility has to be on the end user to actually make sure everything is done correctly.

These cars are race vehicles and DO require some knowledge from the end user to perform at their best.

Follow these tips and you will have zero problems with gears wearing out prematurely

Enjoy your upgrade from the B44.3
