As with ALL differentials ours needs a proper break in period.
This allows the gears to work harden and smooth themselves
before hard use for cooler operation. If this isn't done you are
risking expensive damage to the gear set that can only be fixed
by replacing the gear set.
There is no hard and fast rule to cover all situations as to the
proper way to break them in. The key is to get some miles/time
on them in short increments while not allowing them to
overheat and break down the fluid.
In certain situations, especially racing, there is very little time if
any to properly break in the gears.
We are now offering a REM finishing process to the gears to
help with this problem. Most every NASCAR team REMs their
gears to help avoid the heat buildup associated with racing.
This is NOT a guarantee that you will not wear out your gears
from improper break in but it will dramatically increase your
odds and for sure they will run cooler.
The cost of this is $250.00, we are sending them to a company
that does NASCAR gears for this service. The cost comes from
the cost of shipping them there, the process, and shipping
them back to us.
Please allow an extra 10 days to your order if you want this
done. We may stock some in the future depending on the
demand.
Below are some pics of a Megahi9 set that has been REMed.
