DIFFERENTIAL

Air Locker for Land Rover

PRODUCT : Air Locker- Air Operated Locking Differential for Chrysler Jeep


DETAILS : 

TRE air locker differential developed by MARXXON mainly for hard off road driving condition, for off road competition. The TRE Air Locker System is a pneumatic locking differential that uses a dash mounted electric switch to activate a vacuum diaphragm which engages the locker. The TRE Air Locker uses a small charge of air from an on board air compressor that in turn activates the locker. When activated, both axle shafts are locked together into the equivalent of a spool providing 100% equal traction to both wheels of that axle with no differential of speed between the wheels of that axle.

Welcome Distributor and Dealer contact us for details.
