{"product_id":"rzr-170-transmission-output-pinion-19","title":"RZR 170 Transmission Output Pinion #19","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe output pinion and ring gear are the final drive set in your RZR 170's transmission — the pinion (this part, position #19) meshes directly with the ring gear (position #18) to send power out of the gearbox. Because they carry the highest torque multiplication in the trans, this pair takes more abuse than any other gears in the case. Whining under load, backlash you can feel, or visibly rounded teeth all point to a final drive that's on its way out.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is the genuine Polaris OEM output pinion, part number 0454556. Factory tooth profile, factory heat treatment, exact drop-in fit — critical on a pinion, where even a slightly off tooth geometry will chew through its mating gear.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eImportant: pinions and ring gears wear together as a mated set. If your pinion is worn, inspect the ring gear (OEM #0454555) closely — in most cases you'll want to replace both at once, otherwise the worn survivor just eats the new part. We stock the ring gear, output gear, counter gear\/shaft, bearings, and seals to knock out the whole rebuild in one order.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e2009–2021 Polaris RZR 170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Polaris","offers":[{"title":"Default Title","offer_id":54030953316636,"sku":"0454556","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/5679\/8748\/files\/rzr-170-pinon-gear-0454556.jpg?v=1783112589","url":"https:\/\/www.drowsports.com\/products\/rzr-170-transmission-output-pinion-19","provider":"DROWsports","version":"1.0","type":"link"}
