GENERIC 070013 Cylinder – 5×15.75 Inch Replacement

The GENERIC 070013 Hydraulic Cylinder is a direct replacement for specific dump trailer models. With a 5-inch bore and 15-3/4 inch stroke, it’s designed for trailers that require a compact cylinder. This makes it ideal for smaller dump beds or as a replacement part for existing systems.

Installation is straightforward, as it matches the original specifications. However, because it’s a generic brand, you may not get the same warranty or support as name-brand options. The stroke length is limited, so it won’t work for larger trailers needing a longer dump angle. If you have a trailer that uses this exact size, it’s a cost-effective fix, but verify compatibility before purchasing.

Buyer’s Guide: What to Consider

Choosing the right hydraulic cylinder for your dump trailer depends on trailer size, weight capacity, and power source. This guide covers key factors to consider.

• Lifting Capacity: Match the cylinder's lifting capacity to your trailer's maximum loaded weight. Overloading can cause failure.
• Stroke Length: Measure the stroke length needed for your trailer bed length. A longer stroke allows a higher dump angle.
• Cylinder Type: Choose between single-acting (gravity lower) or double-acting (powered lower) for control and safety.
• Pump Compatibility: Ensure the pump's flow rate and pressure match the cylinder's requirements for efficient operation.
• Build Quality: Look for robust mounting brackets and high-grade steel construction to withstand heavy use and harsh conditions.

Conclusion

Selecting the best hydraulic cylinder for your dump trailer involves balancing lifting capacity, stroke length, and build quality. For heavy-duty agricultural or construction use, the Primary Mover kits offer exceptional strength and easy installation.

For smaller trailers or budget-conscious buyers, the VEVOR scissor hoist kit provides reliable performance with safety features. Always match the cylinder to your trailer’s specifications for safe and efficient dumping.
