Additional Notes

  • The Redrock TH280 and TH280S, both fitted with the Iveco 4.5 Tier 3 engine, share identical front and rear differential fluid capacities of 10 liters each, meaning the axle assemblies on both models are dimensionally equivalent in terms of fluid volume.
  • The TH320 with the Iveco 4.5 Tier 3 engine, introduced from 2009, also carries a 10-liter capacity for both front and rear differentials, consistent with the axle design seen across the Iveco-powered TH280 and TH280S variants.
  • The Redrock TH300 with the Perkins 1004.4T engine, produced from 1999-2004, specifies a substantially larger differential fluid capacity of 23.5 liters for both the front and rear axles. A capacity of this magnitude typically reflects a heavier-duty axle housing designed for greater load-bearing demands.
  • The gap between the 10-liter capacity of the Iveco-powered models and the 23.5-liter capacity of the Perkins-powered TH300 represents a difference of 13.5 liters per axle, indicating a fundamentally different axle assembly rather than a minor design variation.
  • All differential fluid specifications across the TH280, TH280S, TH300, and TH320 are listed under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty cycles.
  • The TH280S shares the same Iveco 4.5 Tier 3 engine and 10-liter differential capacities as the TH280 but covers a longer production span of 2003-2009 compared to the TH280 range of 2003-2006, suggesting the S variant continued in production after the base model was discontinued.
