  • Shafts are hard-chromed, preventing rusting and essentially creating a self-cleaning system. Shafts are also polished to a mirror-like finish, ensuring extended seal life.

  • Cans hold the bump stop around the entire diameter, providing 360° coverage without any pinching like traditional pinch-style cans
  • Sleeves built to allow room for shrinkage during the welding process
