I don't know why they're doing this but Redcat currently has the 25t metal diff gear sets (Part #50116) on clearance for under $5. I can't match that price so here's a link where you can buy them directly from Redcat:
50116 - 25t Metal Diff Gears
You can also check out their clearance page here for other discounting Rampage parts
'till next time
