"To be tested anywhere in the Australian outback is challenging, but to be tested under 'extreme' competition conditions would leave most 4WDrivers shaking in their boots.

Luckily the TJM Pro Locker had been there before; 20 years before, again and again, as we researched and continued to improve its capability.

Today the TJM Pro Locker stands alone.

With an innovative air operated differential locker that, at the flick of a cabin switch, allows you to send equal drive to both wheels and the unique piston style actuator eliminates the risk of oil entering the airline.

With a unique one piece cross shaft (instead of the usual three) adding to its strength, as does the hardened thrust washers, 3/8" bolts holding the hemisphere together and larger pinion gears.

And with a separate pneumatic system that has no internal 'o' rings or oil seals adding to its operational simplicity and low maintenance, whether you're a hard core competitor or a weekend wheeler."

Tech Notes:
This Toyota 8.2" rear differential uses shims to adjust backlash instead of the typical Toyota threaded adjuster.
