hb pro diff?

[RC-Monster Mike]

I have the UE drive cups for those in the need as well. 8mm bore drive cups are needed. Any 8mm drive cup should work(UE, ofna, HB, etc.).
The lightning diffs come in two flavors - Buggy and truggy. The truggy diffs have a lower ratio and are helical cut(ring/pinion). These are a great choice for center diff/direct drive applications.
The buggy diffs have the standard 1/8 buggy ratio (3.31:1) and will work exactly like the UE diffs or any other 1/8 diff setup. The ring/pinion gears are not helical cut on the buggy diffs.
Both have hardened internal gears.
