HardBlock Electric Locking Differentials for Off-Road Vehicles

HardBlock manufactures electric locking differentials for off-road vehicles, including Toyota, Jeep, and other 4×4 platforms. HardBlock Electric Lockers are designed for demanding terrain and high drivetrain loads, providing positive differential locking when you need additional traction.

Find Your Front or Rear Differential Locker

Use the catalog filters to select your vehicle and find the right locker. Exact fitment depends on the model, year, axle type, spline count, gear ratio, and factory differential configuration. Always check the product page to confirm compatibility before ordering.

12V Electric Operation—No Air Compressor Required

HardBlock Electric Lockers operate on 12V power and require no air compressor, air lines, or other pneumatic components.

Our electric locking differentials are designed to engage while driving and under load, helping maintain traction in demanding off-road conditions. HardBlock lockers have also been tested by racing teams competing in RFC events, where drivetrain components experience high loads and repeated shock impacts.

3-Year Warranty and a Lifetime Warranty on the Locking Mechanism

Every HardBlock Electric Locker comes with a 3-year product warranty, plus a lifetime warranty on the locking mechanism. We stand behind the quality of the complete assembly and the durability of its core locking components. See our warranty policy for full coverage details and terms.

6-Month Return or Exchange Guarantee—Even After Installation

Install it. Test it. Experience HardBlock for yourself.

We offer a 6-month return or exchange guarantee, even after installation. If your locker does not fit your vehicle or does not meet your expectations, you can return or exchange it under the terms of our return policy.
