Additional Notes

  • The rear differential fluid capacity across both configurations is 1.4 liters, which represents a service fill volume typical of a limited-slip or conventional rear differential unit rather than a full overhaul quantity.
  • The SRT Viper 8.4 V10 covering 2013-2014 and the Viper 8.4 V10 covering 2014-2018 share an identical rear differential fluid capacity of 1.4 liters, indicating no variation in differential sizing between the two designations despite the naming change.
  • The service interval for rear differential fluid is specified at 18,000 miles or 18 months under normal use conditions, meaning the interval applies to standard driving circumstances rather than track, towing, or other demanding operating environments.
  • The 18,000-mile or 18-month interval, whichever comes first, reflects a time-based component alongside the mileage threshold, which accounts for fluid degradation that can occur independently of distance traveled.
