The kit includes the top ring, second ring, and oil ring, and carries OEM cross‑reference numbers 13012-HN5-671 and 13012-HN5-672 to ensure an exact aftermarket match. With chrome‑faced rings designed for durability, this replacement helps reclaim power, reduces oil consumption, and fights blow‑by when the going gets tough. Precision manufacturing in Japan backs every rebuild to stand up to real‑world wear.\u003c\/p\u003e\n\u003cp\u003eWhen ring wear sets in, compression falls, oil rings can drag oil into the combustion chamber, and throttle response fades. This OS 0.50 oversize kit is designed to seal the top end again, delivering consistent power delivery and reliable performance for trail riding or farm tasks. It provides a trusted, aftermarket option that maintains engine reliability under harsh conditions where you depend on every RPM.\u003c\/p\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 350 FM (Rancher)\u003c\/td\u003e\n\u003ctd\u003e2000-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 350 TM (Rancher)\u003c\/td\u003e\n\u003ctd\u003e2000-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 350 FE (Rancher 4x4)\u003c\/td\u003e\n\u003ctd\u003e2000-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX 350 TE\u003c\/td\u003e\n\u003ctd\u003e2000-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX Rancher 350 4x4 (FM\/TM\/FE\/TE)\u003c\/td\u003e\n\u003ctd\u003e2000-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Reference Part Numbers\u003c\/td\u003e\n\u003ctd\u003e13012-HN5-671;
