Rolls-Royce Mileage Blocker Installation Service

Protect your Rolls-Royce’s odometer during dyno testing, track preparation, or off-road events with our expert mileage blocker installation service in Slough. We specialise in Phantom, Ghost, Wraith, and Cullinan models, providing precision installations tailored to luxury performance vehicles.

A mileage blocker ensures your Rolls-Royce records accurate mileage data during testing while preventing unnecessary miles from being added. These modules are designed strictly for off-road or dyno use, and while our installation is professional and reliable, we do not guarantee that they are undetectable.

Our Slough workshop guarantees model-specific, safe installation, letting Rolls-Royce owners maintain luxury performance and vehicle integrity while using a mileage blocker. You can trust our team for discreet, efficient service for your high-end vehicle.
