Product Summary

The PJD-12-20-ADS-K is a tandem add-on kit that includes two 12,000 lb rated double-acting hydraulic trailer jacks, a selector valve, hydraulic hoses, and fittings. Designed for trailers with an existing compatible hydraulic power unit, this kit allows you to add synchronized hydraulic landing gear to your trailer without investing in a new HPU. The selector valve enables seamless switching between the jack circuit and other hydraulic functions, such as the dump hoist.

Ideal for heavy-duty trailers requiring balanced lifting, this kit combines the benefits of tandem jacks with the simplicity of an add-on installation.

Key Selling Points

• Tandem Add-On Kit: Two 12,000 lb jacks for 24,000 lb combined capacity, using existing HPU (source: type and params).
• Selector Valve Included: Allows integration with existing hydraulic circuits (source: type).
• Cost-Effective: No need to purchase a new power unit, saving cost and space (source: selling_point).
• Double-Acting Operation: Repower to raise and lower the trailer easily (source: params).
• Synchronized Movement: Jacks extend and retract together for balanced support (inferred from tandem configuration, but we don't have explicit flow divider in this kit, so careful: the source says tandem add-on configuration includes two jacks, selector valve, hoses and fittings, but does not mention flow divider; thus don't claim flow divider).
• 40-Inch Combined Travel: Each jack has 20-inch travel, providing flexibility for leveling (source: params).
