You can find LTC and HTC gears easy enough by looking through AEs website. HTC come in the kit, so they are the plastic gears that have been available for years. LTC is the new stuff.
I recently switched from the old HTC plastic to the newer LTC plastic and the diffs end up 2g or so lighter each due to less milling on the back of the larger gears. Less oil, more plastic.
Maybe this explains the punch difference-
The LTC are so smooth in the center diff that to get an equivalent to 200k-500k HTC you would have to run 1m LTC. It's much easier to rebuild diffs with 200-500 than over 1m, that's why some guys stick with the old gears in the center. The LTC can bleed out power to the front wheels, atleast that's what I've understood from other drivers.
