The Detroit Locker assembly itself is a marvel of engineering, featuring a patented internal mechanism that automatically locks both wheels together during a turn, providing maximum traction and reducing tire wear. This design offers exceptional performance in challenging off-road conditions, allowing you to conquer obstacles with confidence and ease.

This complete car kit comes with comprehensive installation instructions, ensuring a straightforward and hassle-free installation process. It is also backed by Detroit Lockers' industry-leading warranty, providing peace of mind and protection against manufacturing defects for years to come.
