  • Tube spacers/gussets that are far stronger than inferior flat bar gussets
  • Protects your vehicle from upward and side impacts, both on and off road
  • Strong enough to jack under
  • Price is for naked design.  Optional under skid plate or aluminium top tread plate can be manufactured - additional cost applies

Physical design – folds and coverage

  • Acts as an easy step into the Discovery 4 & 3
  • Ultimate strength and ground clearance with replacement sills that are folded to hug the full length of the sill
  • Allows movement between the ladder chassis and monocoque body by purely mounting to the sill
  • Maximised rigidity and strength by connecting the sills and the monocoque body with all 11 fixing points per side utilised
  • Insures the plastic inner guards can’t get caught up with the rear tyres with the rear retainers
  • Maximised protection with rock rails that run the full length of the replacement sills
  • Rock rails act as a step with 95mm protrusion to the tube's outer edge
  • Bolts are zinc plated to prevent the seizing corrosion issues with black steel bolts

Material and processes used in manufacture

  • Replacement sills - 4mm Tru Spec steel tube maximises strength and protection - the right combination of strength and weight
  • Rock rails - 42mm diameter x 4mm wall thickness 350 MPa steel tube - protrudes 95mm to the outside edge of the tube
  • Gussets - 42 mm diameter x 4mm wall thickness 350 MPa steel tube - tube gussets are  stronger than flat bar
