What are Lockers?

How They Work & Why They're Essential for Off-Roading

Lockers are specialized devices installed in vehicle axles, ensuring both wheels on an axle spin at the same speed. Engaging lockers prevents wheels from spinning at different rates, delivering equal power and torque to both wheels, which is crucial for off-road driving.

How Do Lockers Work?

When activated, lockers mechanically connect wheels on the same axle, forcing them to rotate simultaneously. This mechanism ensures equal power distribution, greatly improving traction, especially on challenging terrains.

Key Benefits of Using Lockers

Enhanced Traction:

• Equal power delivery to wheels increases traction, especially beneficial on loose dirt, mud, rocks, or slippery surfaces.

Improved Control and Stability:

• Equal wheel speed helps maintain stability during complex maneuvers such as steep climbs, mud crossings, and rocky trails.

Increased Safety:

• Lockers reduce the risk of losing control or sliding by maintaining constant traction.

Boosted Driver Confidence:

• Knowing your vehicle can handle challenging terrain helps you confidently explore more difficult off-road routes.

Superior Off-Road Performance:

• Prevents one-wheel spin, ensuring your Jeep can overcome tough obstacles effectively.

Versatility:

• Selectable lockers allow you to switch between locked and open differentials, adapting your vehicle’s performance to various terrains.

Drawbacks of Using Lockers

Despite their benefits, lockers also present specific challenges:

Difficulty Turning (Axle Binding):

• Lockers cause both wheels to rotate at the same speed, making tight turns challenging.

• Tires may scrub or drag, creating resistance and potentially reducing maneuverability.

Increased Stress on Drivetrain:

• Axle binding adds stress on differential, axle shafts, and drivetrain components, increasing wear and potential for damage.

Types of Lockers

Lockers are available in several varieties, each suited to different needs:

• Selectable Lockers: Engaged manually via switch, offering flexibility.

• Automatic Lockers: Automatically engage based on wheel slip.

Choosing the right type depends on your specific off-road needs, vehicle setup, and preferences.

Frequently Asked Questions (FAQs)

Q: When should I use my lockers?
A: Engage lockers in challenging terrain where traction is compromised, such as mud, rock crawling, or steep inclines.

Q: Are lockers necessary for casual off-roading?
A: Lockers significantly enhance capability, but they aren't strictly necessary for mild off-road trails.

Q: Can lockers damage my Jeep?
A: Incorrect or prolonged use on hard surfaces can cause drivetrain stress. Proper technique and selective usage mitigate these risks.

Q: Do lockers affect normal road driving?
A: Selectable lockers disengage for normal driving, so there’s no negative impact on everyday handling.

Tips for Effective Use of Lockers

• Throttle Control: Apply smooth throttle inputs to minimize stress on the drivetrain.

• Steering Technique: Adjust steering gradually to navigate turns more efficiently with lockers engaged.

• Terrain Awareness: Engage lockers only when necessary to prevent unnecessary drivetrain stress.
