Buyer’s Guide: What to Consider

Choosing the right landing gear for your semi trailer means balancing lift capacity, durability, and ease of use. This guide covers key factors to help you make an informed decision.

• Lift Capacity: Lift capacity determines how much weight the gear can raise. Higher capacity is essential for heavy loads, while lower capacity may suffice for lighter trailers.
• Static Load Capacity: Static load capacity is the maximum weight the gear can support when parked. Ensure it exceeds your trailer's loaded weight for safety.
• Gear Ratio: Dual-speed gears allow you to switch between fast, low-torque operation and slow, high-torque lifting. This saves time and effort during setup.
• Cross Shaft Length: The cross shaft length must match your trailer's mounting width. Standard lengths like 59-3/4 inches fit many semi-trailers, but always measure first.
• Build Quality: Durable materials like steel with powder coating resist rust and wear. Heat-treated gears and premium lubricants extend lifespan in harsh conditions.

Conclusion

Selecting the right landing gear for your semi trailer comes down to your specific needs. For heavy-duty reliability, the Mytee Products kits offer exceptional lift and static load capacities. If you want to speed up operations, the TurboJack drill adapter is a game-changer.

Ultimately, the Mytee Products 2 Pack provides the best value for those needing multiple sets, while the single kit is perfect for a single trailer. The World American crank handle is a simple, affordable replacement part.
