ARM’s 6” or 9” under tailgate spreaders are truly unique due to the unmatched level of flexibility. Our design allows you to configure the spreader to service multiple tasks while controlling costs and maintenance time. With the ability to discharge both left and right by just reversing hydraulic flow, flipping the auger and moving the spinner, an operator can quickly configure the spreader to the task at hand. With optional accessories like a bermer and central discharge auger, this spreader makes flexibility easy.

Other unique benefits for the ARM – TruckCorp LLC under tailgate spreader are the standard top grate that prevents salt clumps from binding the auger as well as the hydraulic lock out system that allows the operator to clean the lower tray without disconnecting the hydraulic lines. Because the spreader is manufactured from 304 Stainless Steel, it will be both durable and dependable for years to come.

  • Lock out and clean without detaching hydraulic line
  • Heavy Duty grate keeps auger from clogging
  • Universal installation on most dump bodies



ARM’s TG-505 is a versatile workhorse for both summer and winter applications. It can evenly spread limestone all summer long and then spread salt as the weather turns cold. A simple adjustment arm controls flow from the spreader and allows it to adapt between salt and limestone gravel. Additionally, the TG-505 is available in both 304 Stainless Steel as well as Carbon Steel.
