Single 3.5″ x 30″ Cylinder Direct Push Lift Kit

Best for mid-size trailers needing straightforward lift without complex mechanisms. This kit uses a single 3.5″ x 30″ cylinder for lifting power across 8′ to 16′ bed lengths. The kit includes a double-acting hydraulic power unit (HPU), hinges, a safety arm, and the cylinder assembly. Best for DIY installers seeking a complete, ready-to-mount solution. Caution: installation requires proper mounting alignment and hydraulic connections to prevent leakage or misalignment during operation.
Primary Mover PF-520-K Hydraulic Scissor Hoist Kit

Better for users needing a robust 10-ton hoist on trailers from 12′ to 16′. This heavy-duty scissor hoist kit includes cylinder, mounting brackets, hinges, hoses, a safety bar, and a 12VDC pump with a 15′ control. Best for professional users or fleet owners seeking reliable, high-capacity dumping. Caution: larger installation footprint may require more mounting space and dedicated electrical wiring.
VEVOR Hydraulic Dump Lift Kit

Best for heavy loads with remote operation. This kit handles up to 10 tons on 12’–16′ trailers or trucks and includes a 10 QT double-acting hydraulic pump, enabling faster bed elevation and descent. It features a mechanical support arm to hold the bed when raised and reduce unintended lowering. Caution: ensure your vehicle’s electrical system can supply sustained pump power without overheating.
7k -90″ Telescopic Dump Trailer Kit

Choose this if you need extreme lifting capacity—over 20 tons—with a telescopic cylinder that extends to 90″ for tall dumping needs. It pairs with a high-flow pump designed for dump trailers and trucks, and installation is described as straightforward. Caution: higher capacity means stricter safety and operator training requirements to prevent overloading or improper use.
PF-310-K 3 Ton Dump Trailer Kit

Best for smaller dump trailers needing reliable 3-ton capacity. This standard kit includes a 12VDC hydraulic pump, mounting brackets, hinges, hoses, connectors, safety bar, and manual. Best for hobbyists or small business fleets. Caution: capacity is limited to 6,000 lb payload; avoid using the kit for heavier loads to prevent premature wear.
Buying Guide
- What capacity do you need? Match bed payload and anticipated loads to kit rating (2–6 tons, 10 tons, or 20+ tons).
- What bed length do you operate? Ensure the kit is designed for your trailer’s length (8’–12′, 12’–16′, etc.).
- Power source compatibility. Do you want a 12VDC pump, remote operation, or manual control? Choose accordingly.
- Installation footprint. Some kits require more mounting space for the hoist and hydraulic lines; measure your trailer before purchase.
- Safety features. Look for safety arms, mechanical supports, and clear manuals to reduce unintended drops.
- Maintenance needs. Consider pump capacity, hydraulic fluid type, and hoses; easier maintenance reduces downtime.
FAQ
- What is the typical installation complexity for these kits?
Most kits include mounting brackets, hinges, hoses, and a pump; installation varies by bed length and existing framing but is designed for field mounting with basic hydraulic know-how. - Can these kits be user-installed on any trailer?
The kits are intended for compatible trailer frames and lengths; verify bed length, mounting points, and electrical readiness before purchase. - What is the purpose of a safety arm or mechanical support?
They hold the bed in the raised position to prevent unintended lowering during maintenance or loading tasks. - Do these systems require professional maintenance?
Routine inspection of hoses, seals, and fittings is recommended; check for leaks and fluid levels regularly. - Are these kits compatible with existing hydraulic systems?
Compatibility depends on pump type and valve configuration; ensure the new kit matches your vehicle’s power and hydraulic routing. - What should I consider when choosing a high-capacity kit?
Higher capacity kits require more robust frame mounting, safer operation practices, and a plan for wiring to support the pump’s electrical demand.
