• Shipping Restrictions: Ships to the lower 48 US states only
• Note: This is ONE module. End tanks, seals, spacers and hardware are not included. Unlike most of this family, the footprint here is unique - 1651 mm x 203 mm matches no other Caterpillar module, so this one can be identified by measurement alone. Ships LTL freight.

Common Use Case or Symptoms:

Replace these when a D9T or D10 is losing coolant from one strip, or when a module has been holed by rock coming back over the blade - big dozers put the cooling pack right in the line of fire and single-strip damage is the normal outcome.

Why Choose Broken Tractor?

• ✅ Unique Footprint In The Family: 203 mm tall against the 137 to 147 mm strips used elsewhere - the one module in this group you can identify with a tape measure.
• ✅ Tallest Module Stocked: A deeper face than the rest of the AMOCS family, matched to the heat load of a D9T or D10.
• ✅ Four Big Dozers: D9T through D10T on a single module.
