High-Specification Used Tractor Units

A reliable used tractor unit is the fastest, most cost-effective way to increase your haulage capacity. When you buy from Asset Alliance Group, you aren’t just buying a second-hand lorry unit; you are investing in a vehicle with a proven operational history.

We stock a variety of axle configurations to suit your specific operation:

• 4×2 Tractor Units
  • Ideal for urban distribution, supermarket work, and maximizing fuel efficiency on lighter payloads.

  • The industry standard for heavy-duty national transport, providing the traction and stability required for maximum Gross Combination Weight (GCW).

Frequently Asked Questions

What is the benefit of buying ‘Ex-Fleet’ from AAG?

Buying ex-fleet means you are purchasing a vehicle that has been maintained to our elite standards. Most of our stock has been under our care since new, meaning we can verify the service history and the vehicle’s overall performance.

Are trailers included with the tractor unit? 

No. Our listings are for the tractor unit (power unit) only. These are standalone assets compatible with any standard UK trailer, sold separately. We do hold an extensive range of used trailers available for purchase or lease if you need a full outfit.

What is the difference between a 4×2 and a 6×2 tractor unit? 

It comes down to payload and manoeuvrability. A 4×2 (two axles) is lighter and more fuel-efficient, well-suited to regional work. A 6×2 (three axles) has a mid-lift axle to distribute heavier loads, making it essential for heavy-duty long-haul operations.

Are your tractor units ULEZ / Clean Air Zone compliant? 

Yes. All units are inspected to ensure full compliance with UK Clean Air Zones (CAZ) and ULEZ standards, so your tractor unit is a profitable, road-ready asset from the moment of purchase.

What are the key features of Asset Alliance’s tractor units?

Our tractor units are sourced from leading manufacturers including DAF, MAN, Scania, Volvo, Mercedes-Benz, and Renault. Because most of our stock has been managed by us from new, we can verify full service histories. Units are Euro 6 compliant, available for immediate collection, and built for both efficiency and power across long-haul and heavy-duty operations.

How does leasing a tractor unit from Asset Alliance work? 

We offer flexible leasing options including operating lease, finance lease, contract hire, and FlexiHire rental, on short or long-term agreements, with or without maintenance packages. Our team will assess your operational needs and structure the arrangement around your P&L, cash flow and tax position. Visit our leasing options page for details.

Can I specify the trailer type when purchasing a tractor unit? 

We sell tractor units and trailers as separate assets. However, our sales team can help you select a compatible trailer, flatbed, refrigerated, curtainsider, box van, or skeletal, from our extensive trailer inventory to complete your outfit. See our trailers page for current stock.

What fuel economy can I expect from a tractor unit? 

Fuel economy varies by make, model, engine specification, and duty cycle. Our stock of Euro 6 units from manufacturers such as DAF, Scania, and Mercedes-Benz Actros are among the most fuel-efficient in their class. Speak to our sales team for mpg data on specific models of interest.

What warranty options are available for tractor units? 

Because most of our tractor units are ex-fleet vehicles we have managed from new, we can provide detailed documented service histories. Warranty terms vary by age and mileage of the vehicle, our sales team will clearly set out what is covered before you proceed.

Can these tractor units operate on European routes? 

Many of our tractor units are fully compliant with European road regulations and suitable for international haulage. Speak to our sales team to confirm the specific compliance status of any vehicle in stock.
