Tekno RCTekno RC LLC M5 Pinion Gear 20t MOD1 5mm bore M5 Set Screw TKR4180 Gears & Differentials

Feels high quality

I have these tekno mod1 pinions in almost every size. Best value for a hardened mod1 gear.

I got tired of stripping out the stock gears and even with locktite they would come loose. After asking around through some groups everyone suggested this one. Now that I have it I see why! Definitely recommend getting this!
