For traction output, strength and durability, the POWERTRAX LOCK-RIGHT Locker. rivals much more expensive competitive lockers sold only as complete case replacement assemblies. It is a leading product because the LOCK-RIGHT delivers as much traction output, its end assembly is exceptionally strong, is much less expensive, and does not require professional installation (because the complete case assembly does not have to be replaced and realigned with precision calibration equipment).
An excellent choice for off-road vehicle applications, the LOCK-RIGHT's operation is fully automatic. Designed to send the engine power to the wheels with the most traction, the LOCK-RIGHT will help get you where you want to go. While traveling straight the LOCK-RIGHT will lock the axles together similar to a spool. However, when the wheels need to differentiate in a turn, the LOCK-RIGHT will allow the outside wheel to rotate faster to complete the turn.
