Mountain’s unbreakable arms are made from High-Grade Extruded Aluminum, making them the industry-standard in terms of durability and strength without the weight of traditional steel arms. Their “teardrop” profile means that they are stronger vertically while also maintaining horizontal torsion, making them more likely to withstand an impact than other arm shapes.

They come standard with a lifetime warranty.

This is a 10' straight arm for manual or electric flip tarp dump bodies with both side and underbody mount spring assemblies, Mountain recommends a 10’ arm for beds between 13’ and 18’ in length.

The bent version of this arm is available here.

Compatible with the following Crossover configurations:
  • K0424 96” or 102” Crossover (Corners & Crosstube)
  • K0420 (102”), K0422 (108”) and K0422C (110”) Crossovers (One-Piece Crosstube)
  • K0960 (Adjustable from 94” to 110”) (3-Piece Crosstube Assembly)
