Check your Locker



“Locker” in this instance doesn’t refer to the metal box used to hold school books and the occasional freshman. A locker for our purposes refers to a locking differential, which is handy to have when traveling over rough terrain. A locker “locks” the two sides of the axle together. In this way, the differential forces the wheels to turn at the same rate, regardless of which one has traction at the moment. When you are negotiating very rough terrain, a locking mechanism will make the difference between moving forward and just spinning. Lockers can be either automatic lockers, which lock themselves under certain conditions, or on-demand lockers, which are completely driver-controlled.

ExtremeTerrain has a great selection of Lockers. There are several types of Jeep lockers available from a variety of manufacturers. Some lockers engage/disengage automatically, while others are operated by cables (Ox Locker), air pressure (ARB Lockers), or an electric switch (Eaton E-Locker). Here are just some of the Lockers Extremeterrain offers:
ARB Air Lockers
Transform your highway-catered, stock Jeep lockers into off-road monsters at no expense to highway performance. Available in over 100 configurations, ARB Air Lockers use a 12-volt air compressor and a pneumatically operated locking system to produce 100% traction for the off-road enthusiast at the flick of a switch. This improved traction also allows for safer and more controlled driving on rugged terrain, preventing vehicle damage and lessening environmental impact.

OX Lockers
For extreme life reliability, OX Lockers are created to meet the needs of the most extreme of off-road enthusiasts. OX Jeep Lockers are made of forged and heat treated steel, and employ the innovative Four Spider Gear Design that makes this ultimate Jeep locker to ensure durability and maximum reliability. Add an aerospace quality cable and forged steel ramped differential cover, and OX Lockers are the toughest Jeep locker to be made in the USA.

Posi-Lok Lockers
Detroit Lockers
Protected parts are working parts. Whether you’re negotiating your Wrangler up an ascent full of jagged rocks, kicking up sand while hauling across the desert, or even just wary of foreign objects or rust-causing wetness on the open road, upgrading your differential covers or adding a guard to your Jeep axles can protect your vehicles vulnerable areas. Defend your Jeeps moving parts and fragile areas to keep those tight situations from becoming disastrous.

Powertrax Lockers
For traction output, strength, and durability, the POWERTRAX Locker provides performance on par with its more expensive, competing Jeep lockers that are sold only as complete case replacement assemblies. Easily installed into existing case assemblies, the POWERTRAX Locker is widely regarded a premium Jeep locker to be used in demanding off-road situations. For severe driving conditions or extreme off-roading, the POWERTRAX Locker will give you the traction you need.

Lock-Right Lockers
The Powertrax Lock-Right Locker is the original locking differential that could be easily installed in existing case assemblies without any special tools or setup equipment. It has been widely used in demanding off-road applications around the world requiring extreme traction output and high-strength.

Auburn Gear Lockers
From over the road daily driving to muddy trails and back roads, Auburn Gear’s high bias Pro Series and High Performance Series limited-slip differentials outperform standard OEM differentials hands down. They deliver more traction and faster engagement for controlled power transfer and lightning-fast reaction to changing load conditions. No matter what your application – the Auburn Gear limited-slip differential is engineered to provide smooth torque-sensing operation with bias ratios to meet your performance needs.

The ELocker™ from Eaton is an electromagnetic locking differential that allows you to instantly change between open and locked differential action with just the push of a button!

  1. A buddy of mine is a faithful reader here and he was trying to explain the different types of lockers to me. I’m sure he knew what he was talking about, but I was having a hard time understanding his terminology. He finally just gave me the link and told me to come and read it for myself. I can see now what he was trying to say but it made more sense to me when I read it myself. Thanks for the lesson.
