HardBlock Lockers
We are HardBlock, a company specializing in the production of high-quality electric lockers. Since 2019, we have been manufacturing top-tier products, and in 2024 we were granted patents in the United States (US12092195B2).
We manufacture Electric Locking Differentials for popular Toyota vehicles, built for serious off-road use and long service life.
Our products are designed for models such as the Toyota Tacoma, Toyota 4Runner, Toyota FJ Cruiser, as well as other compatible Toyota vehicles. Exact fitment depends on the specific model, axle, and drivetrain configuration. Please refer to the product page to check compatibility with your vehicle.
Our Electric Lockers have been tested by racing teams in RFC series competitions.
Unlike many competing solutions, our Electric Lockers are built for demanding off-road conditions: high loads, engagement while driving, and repeated shock impacts in real-world use.
We stand behind the quality of our products and offer a 6-month return or exchange guarantee.
This guarantee applies even if the locker has already been installed. If the product does not fit your vehicle or does not meet your expectations, it can be returned or exchanged within 6 months of purchase.
