How does a semi diff lock work?
The simple answer is a differential lock (or diff lock) locks both wheels on the same axle in order for the wheels to spin at the same rpm. So, the difference is between one set of wheels moving at the same speed (diff lock) or all drive wheels moving at the same speed (IAD).
What are lockers on a semi truck?
Locking differentials (generically referred to as “lockers”) can lock the axles together to provide 100% of available torque to the wheel with traction.
What do axle lockers do?
If you had a locker installed, when you hit the gas (and you’re basically going straight), the locker transfers the power to both drive axles, thus to both wheels. It does exactly what the name implies, it “locks” the axles together. Both wheels receive their power evenly and to the same degree.
How fast can you go with diff lock on?
When differential locks are engaged on a vehicle, how fast can you drive? You should not exceed 25mph with diff locks engaged. Differential locks allow the driver to force the vehicle to use all (or both depending on where the locks are located) tires while making a turn.
Which trucks have locking differentials?
What Trucks Come with Locking Differential?
- Ford F-150 Raptor. The Ford F-150 Raptor is a very popular pick-up truck known for riding well on desert terrain.
- GMC Sierra AT4. The GMC Sierra AT4 has a rear locking differential.
- Toyota Tacoma.
- RAM 2500 Power Wagon.
- Jeep Gladiator.
- Locking Differential.
- Other Options.
Do I need lockers?
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.
Which trucks have front and rear lockers?
The Toyota Tacoma and 4Runner; Nissan Frontier; Ford Raptor, F-150, F-250 and F-350 have e-lockers. The venerable Ram 2500 Power Wagon has electronic locking front and rear differentials and a gear-driven limited-slip in the rear.
What happens when you put an axle lock on a truck?
The locked axles will tend to push you straight when you want to try. Overcome this by easing off the throttle in turns. This is a picture that shows a truck with both options. The middle switch, with the “X” between the axles is the power divider.
What kind of locker does a Toyota truck have?
The Toyota Electric Locker is a selectable locker that replaces the entire third-member and may require axle housing modifications. Made by Toyota and offered on 1993 & newer model trucks, the “E-Locker” uses an electric motor and worm drive assembly to engage or disengage the locker via a shift fork and collar.
Which is better differential lock or inter axle lock?
Interlock locks the differential between the axles. You will still spin the tires with the least traction on each axle. Differential locks lock the differentials in each axle. Both wheels on one axle will turn the same speed, but the power will go to the axle with the least traction.
Why do you need a front locker in two wheel drive?
Some argue that having a locking differential in the front axle will allow the vehicle to climb better. And, that when in two-wheel drive, a front locker is unnoticeable. Others feel that a rear locker is more advantageous on the trail, where it can keep pushing you forward. We could write an entire story on this topic alone!
