{"product_id":"arrma-ara-2647-olc-transmission-protector-50t","title":"ARRMA ARA-2647 OLC Transmission Protector 50T","description":"\u003cp\u003eThis pre-assembled ARRMA OLC (Over Load Coupling) transmission protector comes built around a 50-tooth 0.8 MOD metal spur gear, ready to install on compatible ARRMA models. It solves the metal-spur dilemma: a metal spur won't strip, but that means shock loads travel deeper into the transmission — the OLC puts a protective fuse back into the system.\u003c\/p\u003e\u003cp\u003eThe coupling is designed to give way momentarily under extreme shock load — the traction snap when airborne wheels touch down at full throttle, the sudden jam of debris — absorbing the torque spike before it reaches gears, diffs, and driveshafts. Under normal driving it transfers power solidly.\u003c\/p\u003e\u003cp\u003eArriving assembled with the metal spur already fitted, installation is a straight swap onto the transmission with no setup guesswork.\u003c\/p\u003e\u003cp\u003eFitment is compatible ARRMA models using the 50T 0.8 MOD spur, including the Infraction 3S platform — confirm against your exploded parts diagram. The package includes one assembled OLC transmission protector with metal spur gear.\u003c\/p\u003e","brand":"ARRMA","offers":[{"title":"Default Title","offer_id":55722886267202,"sku":"ARA-2647","price":0.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/www.powerhobby.com\/products\/arrma-ara-2647-olc-transmission-protector-50t","provider":"PowerHobby","version":"1.0","type":"link"}
