How does a TJM Pro locker work?

How the TJM Pro Locker works. THE TJM Pro Lockers are an air-operated locker that forces air into the diff from an onboard air compressor via an airline, which engages a locking ring over one axle gear. This in turn locks the carrier and pinion gears, forcing drive to be sent to both left and right wheels equally.

What is a TJM Pro Locker?

The TJM Pro Locker is a highly advanced differential lock. With the flick of a switch, a TJM Pro Locker sends compressed air to engage a lock ring that links the carrier and the side gears, resulting in equal drive to both axles.

How do air diff lockers work?

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 does an automatic locker work?

An automatic locker mechanically locks both tires on an axle together when under power, but also has a torque-sensing function that will unlock one tire and allow it to spin faster than the other when coasting (such as when going around a corner).

How fast can you drive with diff lock on?

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's better front or rear lockers?

A vehicle will steer better with only the rear axle locked than it would with only the front axle locked. The advantages of the bonus traction most often far outweigh the disadvantages of understeer, but generally you will usually find no noticeable understeer as a result of only having a rear Air Locker engaged.

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.

How does an automatic locking differential work?

Auto-locking differentials are activated when one wheel spins about 100 rpm faster than the other wheel on the same axle. The difference in speed causes a mechanism to activate and lock the axles together.

Which is better limited slip or locking differential?

An automatic locking differential can unlock and allow the inside wheel to rotate freely, but only when power is limited. The limited slip differential will allow some slipping between the two side gears, this allows both wheels to get equal traction even though one is spinning faster than the other.

How do air lockers engage?

General ARB Air Locker Use

ARB Air Locker differentials can be engaged and disengaged at the flip of a switch. When you need the extra traction, simply turn on your compressor, approach the difficult terrain, take your foot off of the accelerator and press the Air Locker switch – even if you are still moving.

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 are the best diff lockers?

The best known driver-controlled diff lock is ARB's Air Locker, but there are TJM ProLockers, Harrop E-Lockers, and a few remaining Maxi-Drive and McNamara units for Land Rovers and Range Rovers.

What is the benefit of a locking rear differential?

Cars only have one differential, but 4X4 vehicles can have up to three differentials – front, centre and rear. A differential lock secures this differential in place, making all the wheels on the axle move at the same speed. This pushes equal power through to all wheels, which is needed when handling difficult terrain.

Should I use diff lock in sand?

An engaged rear differential lock will ensure there's no loss of forward momentum… However, in soft sand they can cause your 4WD to dig into the sand and become bogged; at the same time in very deep, soft sand they can help you to keep the power poured on and grunt your way out.

Are lockers good in snow?

Lockers are good for snow because they make each wheel move at the same pace. Each wheel moving at the same pace helps you gain traction while driving during poor weather conditions, such as when it is snowing. Without lockers, one wheel can spin freely after losing traction.

Are 4x4 lockers important?

Front and rear lockers are especially effective pulling or pushing out of a cross-axle stuck. Cross axle means a front and rear tire is able to slip. With normal 4WD, you are stuck. By locking the front or rear, you will move forward as long as you have traction.

Does a locker replace the carrier?

It is designed to replace the gears inside of a regular open differential. Everything is contained within the carrier. The second type is the full carrier locker. These lockers replace the entire carrier and are usually much stronger than the lunch box lockers.

Do I really need a rear locker?

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.

What does Twin locked mean?

Locked twins is a rare complication of multiple pregnancy where two fetuses become interlocked during presentation before birth. It occurs in roughly 1 in 1,000 twin deliveries and 1 in 90,000 deliveries overall.

Can you lock differential 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.
