A quality wet kit is a significant investment in your truck’s hydraulic capabilities, but the £2,000 to £3,000 you’ll spend is well worth it for the years of service it’ll provide.
Your vehicle’s hydraulic tank capacity, pump ratings, and gearbox compatibility dictate which wet kits suit it. The good news is that options range from basic tipping systems to premium combination units for intensive applications.
Combination systems and specifications
Twin-line combination kits are more expensive than single-line kits but offer more capabilities for walking floors and ejector trailers. They include a 200L aluminium tank and a high-performance pump delivering up to 108L per 1000 RPM at 350 BAR working pressure.
These match modern automated and manual transmissions across significant truck brands — the enhanced flow control and pressure rating suit demanding applications.
Tipping configurations
Basic tipping systems cost less but still include essential components like a side-mounted aluminium tank, bidirectional pump, PTO block, and cab controls.

Depending on the mounting position, the tank capacity ranges from 190L to 200L, with working pressures from 250 BAR. These systems suit standard tipping operations and offer reliable performance for everyday use.

Premium features and capabilities
High-end systems include inline pressure relief valves, enhanced torque ratings up to 531 Nm, and stainless-steel construction. The 25-micron filtration and air breathers protect your investment during intensive operation.
Additional features like rotary couplings and ball valves provide operational flexibility. Premium kits often include confirmation switches and LED displays for system monitoring.
Installation requirements
Your price includes VAT but excludes hoses, labour, and programming. You’ll need qualified engineers for installation to handle PTO integration and ECU setup properly.

It’s also wise to purchase the hydraulic fittings and adapters necessary for retrofitting before delivery to keep your build on schedule.
Getting the right advice
Contact us to specify the correct kit for your truck’s make, model, and application. We’ll advise you on compatibility with your gearbox and ensure you get equipment that matches your operating requirements.
When making your selection, consider factors like the duty cycle, operating environment, and required flow rates.
Long-term considerations
Quality components, including stainless steel valves, precision-engineered pumps and filtered breather systems, contribute to exceptional service life. Regular maintenance and proper installation help prevent premature wear.
While premium systems cost more initially, their durability and capabilities often justify the investment for intensive commercial applications. Additional reading: How much do used truck engines cost in 2025?
