Fitment & Compatibility

Will This Truck engine Fit My Vehicle?

Getting the right part first time saves you time and money. Because this is a genuine imported truck engine, the surest way to confirm compatibility is to match it against your specific vehicle before you order.

How to Check Compatibility

Have your vehicle registration and its engine code to hand — you will usually find part codes stamped on the unit or listed on your V5C logbook.
Compare the details in the product title and specification with your own vehicle’s make, model, year and variant.
If you are unsure, our team will check the fitment for you before dispatch — just get in touch with your reg.

Delivery & Guarantee

Every truck engine is inspected before it leaves us, securely packed and dispatched on tracked couriers across the UK and mainland Europe, backed by our standard quality guarantee.
