Re-Designed and Improved Arctic Cat 300 4x4 Regulator Rectifier (years 1998, 1999, 2000 or 2001). This unit has a higher output capacity then the OE unit. Approximately 8% more efficient than the OE regulator rectifier. Meets or exceeds factory specifications. Arctic Cat split the years on some models; this regulator rectifier will replace Arctic Cat # 3530-014. If you are trying to replace a different OE number, please let us know (the only difference is in the connector). We have both regulator rectifiers for your Arctic Cat.
Your Original Regulator Rectifier may or may not have this number stamped on it: SH572A-12
Replaces OEM number: 3530-014
