About Us
Who We Are
RR4X4 Works is the UK's dedicated specialist in Land Rover and Range Rover engine replacement, supply, and reconditioning. With over 15 years of engineering experience and more than 400,000 satisfied customers across the United Kingdom, we have built our reputation on one simple principle: doing the job properly, the first time.
We exist because Land Rover and Range Rover owners deserve better — better diagnosis, better parts, better transparency, and better value than what main dealers typically offer.
What We Do
We operate as a complete engine solution platform. Whether your Discovery 4 TDV6 crankshaft has snapped, your Range Rover Sport is suffering timing chain failure, or your Defender needs a fully rebuilt engine for expedition use, we provide a single, seamless service that covers everything:
- VIN-matched engine sourcing — used and reconditioned units matched precisely to your vehicle's engine code, not just its model
- Supply and fit packages — coordinated through our national network of MIRA-vetted specialist garages
- Competitive, transparent pricing — 30+ customised quotes delivered within minutes, saving customers up to 60% compared to main dealer rates
- Comprehensive warranty cover — 3 to 36-month unlimited mileage warranties, documented in writing
Our Specialist Network
Every garage in our network passes a rigorous 9-point verification process, including checks on MIRA accreditation, Land Rover-specific training history, and proven rebuild portfolios. We connect you only with master rebuilders for whom reconditioning Land Rover and Range Rover engines is their primary expertise — not a side job.
Our Reconditioned Engines
Every reconditioned unit we supply is rebuilt to exact manufacturer specifications. Our certified technicians carry out full cylinder head refurbishment, precision block re-boring, crankshaft grinding and polishing, and complete assembly using OEM-quality components. Each engine is dyno-tested before despatch and covered by a comprehensive warranty.
Our Used Engines
For customers with tighter budgets, our used engine inventory is hand-picked exclusively from low-mileage, UK-salvaged vehicles with full provenance history. Every unit passes a 50-point inspection — including compression and leak-down tests, digital bore scope examination, and turbocharger health assessment — before we offer it to any customer.
Additional Services
Beyond engine supply and fitting, our network also provides: engine carbon cleaning, DPF and turbocharger refurbishment, video health checks, nationwide recovery coordination, and 0% finance options to make major repairs manageable.
Why Thousands of UK Drivers Choose Us
We do not guess. We do not cut corners. And we do not sell you a solution without first understanding your specific vehicle. Every recommendation we make is based on your full VIN, your symptoms, and your long-term driving needs — not a generic quote off a price list.
If your Land Rover or Range Rover needs an engine, we are the team trusted to get it right.
