Front Diff Fill Plug to suit Toyota 

If you've ever changed your front diff oil, you'll know how tricky it is to remove the original fill plug. The plug's position makes accessing it with an allen key awkward, and the 10mm Hex head is easily stripped and irreparably damaged, which can result in an expensive trip to the mechanic.

Our Front Diff Fill Plug uses a solid 19mm Hex that won't strip or round, so you can have peace of mind knowing your next diff oil change will always be fuss-free. 



  • CNC machined with an electroplated zinc coating. 
  • 19mm Hex head that won't strip or round with use. 
  • Allows easier access from underneath, as well as giving additional access from above using an open spanner. 



  • HiLux N80
  • LandCruiser LC200
  • Prado 90 / 120 / 150
  • FJ Cruiser

This plug is designed to replace genuine Toyota Part Number 90341-18032. You can check what plug your vehicle uses on Amayama

Great Quality Product

To most, it might just "be a bolt", but try holding one of these in your hand and you will get what I mean. Such a quality piece of kit. But isn't the advertised 19mm... I had to use a 20mm for it to work. All my 19mm sockets/open end/ring spanners all could not fit. Not a big deal, just thought I should mention it. Highly recommended

Kaon Diff Fill Plug

Much easier to change out than the factory plug. Would be great to see it come with a new washer like the drain plug does.
