Detroit Lockers offer full and positive traction for serious rock crawling.

Detroit lockers work like a ratchet wrench, allowing one wheel to spin faster as needed for going around corners but does not allow either wheel to go slower than the drive speed. Totally automatic with no buttons to press. Solid reliability.
