What are the benefits of air lockers?

The main benefit that an Air Locker has over an electronic-locker is its instant activation. By comparison to the majority of electronic lockers, an ARB Air Locker engages instantly and at any speed; furthermore, an ARB Air Locker has no operating speed limitations.

Are air lockers worth it?

Air lockers are the real winner. Yes, the cost is higher, but the reliability and instant engagement dubs them the superior unit.

What is the purpose of air lockers?

When activated, the air locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times.

How fast can you drive with air lockers?

At what speed can I engage my ARB Air Lockers? An ARB Air Locker can be engaged at any speed as long as both wheels are spinning at the same rate. If one wheel is spinning faster than the other, what is called “crash locking” will occur and can cause damage to the internal gears.

How long do air lockers last?

The O-ring seals ARB builds into Air Locker differentials actually have a lower wear coefficient than the metal surfaces they run against, and we have seen Air Locker O-rings last in excess of 500,000km and still perform flawlessly.

ARB Air Locker Benefits

What can you not do with an air locker?

Do not engage either Air Locker when you are hard on the accelerator and with wheels spinning. This is what we term as 'crash locking' and will ultimately cause damage to the Air Locker or other parts of your drivetrain. It's the equivalent of trying to change gears without the clutch.

Which is better e locker or air locker?

This means e-lockers are significantly more reliable and is why they are the preferred option for many commercial users and manufacturers. They are, however, slightly less instantaneous than air lockers and some older models can take a few seconds to engage.

Can you turn with lockers engaged?

When engaged, differential lockers apply power equally to both wheels on an axle, regardless of how much resistance exists at each wheel. This helps the vehicle to have full traction available at both wheels on the axle. It can, however, limit the vehicle's ability to turn.

How fast can you go with rear diff locked?

How fast can you drive when the differential lock is engaged on the vehicle? When using the differential lock, your speed should not exceed 25 mph.

What do air lockers do on 4WD?

ARB Air Lockers

In a vehicle with open differentials in 4WD mode, drive can only go to two wheels at any given time. At the flick of a switch, an ARB Air Locker can send equal drive to both wheels on an axle allowing you to take advantage of the wheels that have traction and push forward along the track.

What do lockers do on a 4x4?

Automatic lockers are those that lock and unlock in response to changing conditions. They default to a 50/50 torque split but are designed to unlock through corners, permitting the tires to go around a corner without scuffing, and then lock again when a torque differential occurs between wheels.

How much does an ARB Air Locker cost?

air locker from arb are about $1300 each not fitted. including hardware. plus a one of purchase compressor for about $300.

Which differential locker is best?

For vehicles with open differentials, a rear locker is by far the more popular choice, as it's more suitable to a diverse range of off-roading situations. “If the vehicle only has open differentials we typically recommend a rear, which will be more effective when off-road hill climbing,” said Sebastian Civitarese.

Are ARB air lockers any good?

After years of testing, we have found that ARB Air Lockers are strong and can take a beating. Yes, ARBs are more complicated in design than other lockers, which has lead to some people fearing the Air Locker.

Do lockers help in mud?

Lockers will definitely help in mud. However, front being locked will make it hard to steer left and right and sometimes you have to saw the wheel to get unstuck. So, use as necessary. In my years of experience, the #1 piece of equipment you need to plow through mud is a big fat set of mud tires.

What does a locker do in a rear end?

Lockers make a huge difference off-road because they double your traction by spinning both tires. If you hang a tire in the air with an open differential, it will just spin while the other tire sits still. Adding a locking differential means that both tires turn at the same speed, regardless of the situation.

Why do I need lockers on my Jeep?

No you don't "need" lockers. A winch will help in self recovery only if you have a good attachment point. If you wheel with friends you're probably going to get un-stuck one way or another with their help. Lockers are going to enable you to do harder trails, just like 40s.

Can you lock your diff while moving?

Never lock while you have a drive wheel breaking traction. You should be stopped or at a very low speed (15 mph or less) when you throw the switch. Max safe road speed is about 40 mph with the lock engaged. You can unlock them while moving.

When should I lock my differential?

First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow.

Does Sahara have locking differential?

Both the Sahara and Rubicon use open diffs with brake-locking, controlled by stability control, by default. Because the car has to brake one tire to route torque to the other tire with traction, some engine torque is wasted.

How do ARB air lockers work?

The ARB Air Locker is a replacement differential carrier that can either operate as a conventional differential, or lock both rear (or front) axle shafts together allowing maximum drive torque to be transmitted to both wheels. The locking function is controlled from the vehicle dashboard by the driver.

Are auto lockers any good?

The good Auto lockers are quite affordable and don't need to be engaged (and disengaged) manually, which means you'll never forget to put it on before tackling an obstacle, or disengage it afterwards. The bad You'll probably notice increased tyre wear (we'll explain why in the point below).
