Product Details

The ARB RD161 Air Locker Differential delivers 100% traction on demand without compromising highway driving performance. Featuring an improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this differential locker represents the pinnacle of ARB's engineering expertise.

How It Works:

The ARB Air Locker employs a pneumatically operated locking mechanism that's activated by a 12-volt ARB air compressor at the flip of a switch. When engaged, the Air Locker prevents the differential gears from rotating, locking both axle shafts together so they turn in unison with the ring gear. This ensures both wheels receive equal power regardless of traction conditions, delivering maximum traction when you need it most. When deactivated, the differential operates like a conventional open unit for normal highway driving.

Key Features:

  • Two-piece design with forged gears for enhanced strength and durability
  • On-demand activation via in-cab switch for instant traction control
  • 100% traction engagement when locked, standard open differential when unlocked
  • Pneumatic activation system powered by 12V ARB air compressor
  • Industry-leading five-year warranty
  • Solid locking mechanism eliminates wheel spin on challenging terrain

Benefits:

Beyond dramatically improving off-road capability, the ARB Air Locker allows for slower, more controlled driving on technical terrain. This reduces the risk of vehicle damage and minimizes environmental impact by eliminating the need for aggressive throttle inputs and wheel spin. The selectable design means you maintain full highway manners and fuel economy when the locker is disengaged, making it the ideal solution for vehicles that see both street and trail use.

So far so good. Ordering was seamless.

Great shopping experience satisfied

Great company. When I started looking into transporting the car I came across many sketchy companies. A lot of bad reviews, complaints about money being taken and not having the car picked up, etc. But Autoplicity had good reviews and I can see why! I paid my deposit of only $50, they picked up the car within 3 days and delivered it in 2 days. The truck driver had excellent customer service! Very happy with this company, I would recommend them and definitely use them again if need be.

Found the part quickly

Best price, almost no wait delivery

Thumbs up!

ALL OK

Autoplicity had the best price by far on the item I was looking for. I paid for 2nd day air shipping and my order total was still less expensive than ordering from any other merchant. My item arrived the day after I ordered it. I will definitely buy from them in the future.

Best price fast shipping. will deffinitly order again

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Best price on the Internet and quick shipping

Very fast and easy ordering system. My order was shipped the next day.

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
