    The GenX Oval Tube Drop Step from Westin is a 4" oval tube, and the primary feature is the step pad that drops down 5" main tube, making the GenX the perfect Nerf Bar for lifted vehicles. The ends of the GenX tubes are welded and sealed, defending against rot from the inside out. The step is constructed of 2" oval tubing with a continuous smooth bend. The continuous tube construction helps strength the step pad by eliminating the multiple welds the often make up other drop steps. Those weld spots create stress points that can brake easily under load. The step is topped with a molded textured step pad designed to not slip when wet. All required installation hardware included.

    Features
  • Easy No-Drill Installation
  • Dropped Step Pad Helps with Higher Lifts
  • Minimal Welds Increase Strength of all Tubes
