Replacement parts for Pioneer Tarp systems — tarp and roller parts, arm assemblies, pivot assemblies, gantry assemblies, valves and hydraulics. Pioneer (now Mountain Tarp Pioneer) is one of the most common tarp systems on commercial refuse and roll-off trucks in North America.
Pioneer Tarp built its reputation on mesh-arm tarp systems — the spring-loaded arm assembly that pulls a mesh tarp across the truck bed. The Pioneer mesh-arm design is widely used on aggregate haulers, waste-industry refuse trucks, and roll-off trucks. The mechanical components (arms, springs, pivots, gantries) wear in predictable patterns and PRT stocks OEM-equivalent replacements.
PRT supports the full Pioneer Tarp parts lineup. Subcategories below organize parts by assembly: tarp and roller parts (fabric and direct-replacement), arm assembly parts (springs and hinges), pivot assembly parts (bushings and pins), gantry assembly parts (frame components), and tarp-system hydraulics.
Identify the failed component by its Pioneer Tarp assembly position and the OEM part number. Pioneer parts are well-documented; most replacements can be matched from a clear photo and the truck's Pioneer tarp model.
For older Pioneer Tarp installations with discontinued OEM parts, PRT can fabricate equivalent components or recommend current-production replacements.
Pioneer Tarp is now part of Mountain Tarp. Older systems may be labeled 'Pioneer' only; newer installations may carry the Mountain Tarp branding. The parts are largely consistent across the labeling change.
Arm-assembly springs — they fatigue from continuous flex cycling. Replace at the first sign of weakened return tension. Mesh tarp fabric is second most common.
Yes. PRT supplies OEM-equivalent Pioneer parts with matching dimensions, materials, and ratings. Provide the OEM part number for confirmation.
3-7 years depending on use intensity. Weather, salt exposure, and cycle frequency all affect spring life.
