ORIGINAL: TrRCER
hmmm interesting find Clermont cause i have had my fair share of cen products and as far as I no the gears in all the 8th scale differentials are exactly the same the rtrs and the pro kits have the same gears there is no difference. maybe when you put on the new gears when you put new fluid in the diffs you noticed a difference cause your running fresh clean fluid.
LOL
