{"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":"PowerHobby","offers":[{"title":"Default Title","offer_id":67651099426904,"sku":"ARA-2647","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/ARA-2647_A0_VR2K03KY.jpg?v=1791387011","url":"https:\/\/beavertonmilestonehobby.com\/products\/arrma-ara-2647-olc-transmission-protector-50t","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
