ARB Lockers offer the ability to turn on and off at the push of a button. Compressed air is used to engage the locking mechanism. When turned on, both wheels are solidly locked to together, completely eliminating wheel spin. When unlocked, the differential operates exactly like a stock unit, allowing unencumbered operation on pavement.
The RD23 works with V6 and High Pinion applications.
In order to use with a 4Cyl application....you will need the ARB 4Cyl Bearing Kit, also sold in this section.
