**TRE4X4 TR101 Air Locking – Dana 30 Front Differential (27 Spline)**

Engineered for the Jeep or 4x4 owner who demands confidence on challenging terrain, the TRE4X4 TR101 Air Locker provides reliable front-axle traction when you need it most. Designed as a direct replacement for the Dana 30 front differential with 27-spline axles, this air-actuated locker engages on command for technical climbs, rocky trails, and deep mud, while maintaining smooth, quiet operation in daily driving.

**Product Details & Application**

**Precise Compatibility**
This air locker is manufactured specifically for vehicles equipped with the Dana 30 front differential and 27-spline axle configuration. It is a direct bolt-in upgrade for models such as the Jeep Wrangler (TJ, YJ) and Cherokee (XJ), requiring no axle modifications for installation.

**On-Trail Functionality**
When your path includes loose rock, steep inclines, or uneven surfaces where front-wheel traction is critical, a dash-mounted switch activates 100% axle lock. This ensures both front wheels pull together, providing the grip needed to maintain momentum and control in low-traction situations.

**Air-Actuation Design**
Utilizing a proven air-operated system, the locker delivers consistent and robust locking force. The design prioritizes mechanical simplicity and field-serviceable components, making it a dependable choice for overlanding, rock crawling, and heavy trail use where electrical complexity is undesirable.

**Durable Construction**
The internal gearset is forged from 8620 steel and 4320 chromoly alloy, materials selected for impact resistance and long-term durability. A two-stage oil management system is incorporated to reduce operating temperatures and wear, contributing to the unit's overall service life under sustained load.

**Warranty & Support**
Your investment is protected by a 5-year limited warranty, covering defects in materials and workmanship. This coverage supports the product's use in both recreational off-road and demanding commercial applications.
