ARB Air Locker

The world famous ARB Air Locker!

ARB developed a selectable locking differential over 30 years ago. This innovative design applies Air pressure to the bonded seal which drives the clutch gear onto the splined gear. This now locks the spiders gears from turning and the result is a 100% locked axle. A flip on the switch releases the air pressure and the return springs slid the clutch gear off the splined gear and the differential is now unlocked.

 

The RD129 will fit the following Toyota 8" Clamshell front differentials with 3.91:1 and up gear ratios.

  • 2003-2009 4Runner
  • 2005-2010 Tacoma
  • 2007-2010 FJ Cruiser
$996.04
