In order to improve the loss traction situation of the open differential when vehicle driveon some uneven terrains (such as: snow, sand, muddy, rocky), TRE innovated the CrabLocker (Air operated locking differential) to solve the open differential traction issue.Crab Locker with its proven design and comparative advantages than other lockers on themarket. Crab Locker equipped on 18sets 4x4 vehicles over 5 years for extreme off roaddrive test, during the 5 years TRE continued to improve its capability and durability. Withits New Air Operated Actuator Design, unique Oil Return System design, Two Piece CaseStructure Design and easy installation feature, Crab Locker finally released on the market.Crab Locker is your best choice for weekend off road trip or extreme 4x4 off road drive.
Why do you need Crab Locker?
How does Crab Locker work?When driving off road on some uneven terrains (such as:snow, sand, muddy, rocky), at some point will cause either afront or rear wheel to lift of the ground or just loose traction.When that happens the power will always take the path ofleast resistance, and the power will be transferred to onewheel, another wheel with no power to drive out of thesituation. There are two ways to solve this problem. One ismomentum, this will get you through in most cases. But thisrequires continuous movement, and will damage the vehicle.The other way to is to install a TRE Crab Locker.
How does Crab Locker work?
The Crab Locker operation is simple and straight forward.Compressed air goes into the selector ring, then air will push the push ring, push ring push 4 pins to engage the lockingring to lock the side gear, now the Crab Locker is lockedand will deliver equal 100% traction to both axles. Both axleshafts have the same maximum traction, which can get thevehicle out of trouble. Turn off the switch to disengage theCrab Locker, the Compressed air release from the solenoidexhaust hole into the oil return line.The lock ring will bepushed by the springs to its original position, Crab Lockerreturns to its open differential function. (The Crab Locker equipped with oil-return system, which protects your air compressor and prevents oil leakage, solving a major defect of theair locker on the market.)
