ARB Under Vehicle Protection Skid Plate (Gray Powdercoat) - 5421100


  • ARB 4x4 Accessories | Part Number: ARB5421100
  • Finish:Gray Powder Coat
  • Fitment:Direct Fit
  • Type:Undercarriage Skid
  • Installation Type:No Cutting or Drilling Required


The first skid plate panels system specifically designed for SUVs, these panels feature the same construction as the current range of panels, i.e.. pressed and folded 3mm steel. Due to the Prado 120/150, 4Runner and FJ Cruiser sharing the same chassis platform, the same skid plate design has been used for the four vehicles. However, a second kit has been built to suit the Prado 150 and 2010+ 4Runner with Kinetic suspension system as a slightly different lower bulge is required in the front panel due to the positioning of the kinetic sway bar. The transmission panel is common to both kits and also to petrol and diesel engine variants. It has a two position mounting bracket providing a lower mount for petrol engine vehicles where the exhaust sits lower than diesel models. The transmission panel is also tapered to the rear to clear chassis bracing that is unique to the Prado/FJ chassis design. Developed with extensive field testing, ARB skid plates give protection to vital underbody components with vehicle specific models protecting steering, engine oil panel, transmission and transfer case where applicable. Panels are easily removed for vehicle servicing and where practical, include access to oil panel drain plugs. Each panel has recessed mounting bolts in vulnerable areas to ensure ease of removal even if the panels become damaged from severe off road service. ARB Skid Plate are fully compatible with all ARB products such as Bull Bars, Side Rail & Steps, Airlocker and OME.

3.0 Good quality but install is hassle

Install instructions have few pics and its confusing because ARB seems unable to print a seperate instruction for FJ instead of the Prado (Gx) Has to have the "stone tray" and the ARB bumper or doubt this works. Has 5pieces and powder coated so its nice for $500 but for transfer case I wasnt so hot on it using the case bolts instead of the factory mount bolts

5.0 Great set!

Awesome setup. It comes with 4 skids. Engine, oil pan, transmission, and transfer case. Instructions are a bit unclear, but looking back, it isn't that bad. Lay everything out beforehand. Not as thick as other skids, but these are 3x thicker than OEM. It should be quite sufficient for the recreational offroader. Great price, and the fit and finish were fantastic.

3.0 not a bolt on install for fj cruiser

The skid plate set is really nice, the plates are more than 3x thicker than stock metal and they mount very rigidly. Sadly the instructions leave a lot to be desired. If you have an FJ cruiser with ARB bumper as I do you will want to use the prado instructions, and you will need to source your own bolts for the front skidplate/stone tray mounting holes. You will need two Grade 10 shouldered m8-1.25x170mm bolts
