Arctic Cat 425/450 series

Differential fluid capacity & service interval

Arctic Cat 425/450 series differential fluid capacity ranges from 250 CM3 to 275 CM3. Service intervals include checking every 300 miles or 3 months and changing every 48 months. The data covers 12 configurations.

Additional Notes

  • Across the Arctic Cat 425/450 series, front differential capacity is consistently higher than rear differential capacity. The front holds 275 CM3 (approximately 0.28 liter) while the rear holds 250 CM3 (approximately 0.25 liter), a pattern present in every configuration listed across all model years.
  • The 425 4x4 (2011-2012) front and rear differential capacities of 275 CM3 and 250 CM3 respectively represent service fill volumes, meaning the amount of fluid required during a routine drain-and-refill service rather than a full overhaul or housing replacement.
  • All configurations across the 425/450 series share a 48-month fluid change interval under normal use conditions, regardless of model year or trim variant. A 48-month interval is relatively long for differential fluid and reflects the sealed, low-contamination nature of ATV differential housings under standard operating conditions.
  • The 450 (2015-2016) and XC 450 (2015-2017) configurations introduce an additional fluid check interval of 300 miles or 3 months under normal use conditions. Earlier configurations for the 450 (2010-2012), XC 450 (2013-2014), and XC 450i 4x4 (2011-2013) carry no such check interval in their specifications.
  • The 300-mile or 3-month check interval on the 450 (2015-2016) and XC 450 (2015-2017) applies to both front and rear differentials equally. A fluid level check at this interval does not involve draining or replacing the fluid, only verifying that the volume remains within specification.
  • Capacity values in the earlier configurations are expressed in cubic centimeters (CM3), while the 450 (2015-2016) and XC 450 (2015-2017) entries express the same volumes in liters. 275 CM3 and 0.28 liter are equivalent measurements, as are 250 CM3 and 0.25 liter, with minor rounding applied in the liter-based entries.
  • The XC 450i 4x4 (2011-2013) shares identical front and rear differential capacities and the same 48-month change interval as the standard 450 (2010-2012) and the 425 4x4 (2011-2012). The "i" designation, which typically denotes fuel injection, does not correspond to any difference in differential fluid specifications among these configurations.
  • The XC 450 trim spans two distinct specification periods: 2013-2014 and 2015-2017. The 2013-2014 period carries only a change interval, while the 2015-2017 period adds the 300-mile or 3-month check interval alongside the same 48-month change interval, indicating a revision in service requirements between those periods.
