Diff Hat Harrop M86 BA Falcon

The Harrop Diff Hat M86 BA Falcon is a great step forward from the factory M86 diff hat. This diff hat is cast alloy and is custom machined.

This diff hat will fit  BA   XR6 Turbo, XR8, GT ,GTP F6 and in sedan format only.

This will not fit BA ute.

The M86 diff hat by Harrop is engineered to increase structural strength and reinforce the rear mont area that attaches to the diff cradle bush.

Having a look at the rear of the diff hat you will notice the alloy casting has a steel insert cast into the hat to reinforce the diff bush bolt a common failure area.

The Harrop diff hat has also an increased oil capacity for differential longevity.

The hat is also complemented with extra alloy fins to enhance cooling of the diff oil , gears and bearings. This will significantly lower gear oil temp.

key features:

  • Cover sand cast from 601-T6 aluminium
  • 4140 Chromoly M16 Thread insert
  • CNC machined
  • Leak tested
  • Improves durability of the rear bush to diff hat connection
