What's the difference between the TRE Air Locker (TR series) and the TRE Crab Locker (TC series)?

The Crab Locker is an improved air locker design featuring:

• New Air Operated Actuator Design - No internal o-rings or oil seals. This increases operational simplicity and reliability by eliminating the most common air leak risks.
• Oil Return System - Prevents gear oil in the differential from traveling up the air line into the air compressor.
• Strongest Case - Made of a simplified two piece machined design.

Enhance the traction of your 4x4 in just about any terrain- rock, clay, gravel, sand, snow, and mud. With this on demand air locker, a simple flip of a switch will mechanically lock the axle providing maximum traction when needed, and maneuverability when not. With the forged differential case and chromoly gears, high quality components, and a solid 5 year warranty; TRE provides a reliable option for those wanting the most out of their off-roading adventures.

The TRE Wave Spring makes locking and unlocking more stable and reliable because the wave spring fits tight radial and axial spaces better. Additionally, the Wave Spring reduces the spring height by 50% compared to ordinary coil springs so there is no need to drill the spring holes deep into the clutch gear, thus increasing the stength of the clutch gear.

Features:

• Provides 100% traction on demand without affecting on road drivability or driveline wear
• Vastly improved traction means less reliance on momentum, which reduces the likelihood of vehicle damage and environmental impact
• Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver’s seat
• Ultra durable and extremely strong - only the highest quality materials used in construction. 
• Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability
• Thoroughly tested and proven design – we know of many Monteros in the USA who have been using TRE lockers for years and we have yet to hear of a single failure.
• Can be used in any transfer case setting - 4WD, AWD, 2WD.
