Product F.A.Q.

How do I know if a part will fit my car?

We got a general fitment information table, which can help you identify if the part will fit your car or not. Also, you can leave your VIN/Chassis during checkout, so our team will verify the fitment for you. If you already paid for your order and the part will not fit your vehicle, we will issue you an instant refund.

How to make an order

At LLLparts.co.uk, you can quickly place an order. After you find the part you need, please select one of the warehouses and add it to your cart.

After that, proceed to checkout, fill in the required shipping information, select the shipping method, and you can place your order.

In some cases, when the item has no weight, we will need to calculate the shipping price individually. Usually, we sum it within 10 minutes during our working hours, and if we are not working, you will receive an email notification.

I can't find parts that I need

Our team of professionals will always help you to find the correct and required parts for your car. If you can't find the parts you need, don't hesitate to get in touch with us by email at support@lllparts.co.uk or use our Live chat option and we will be happy to help you.

How I can track my order?

For tracking your order, you will need your order number and email address.

You can track your order by visiting the order tracking page here.

Order Status Tracking

How I can return an item?

You can find the return form in the top right corner Help me -> Begin a return.
Buyer has 100 calendar days from the date he has purchased it to return an item.
To be eligible for a return, the item must be unused and in the same condition that the buyer received it.
Item must be in the original packing (factory sealing should not be damaged).
Once we receive your item, we will inspect it and notify you that we have received your returned item. We will immediately notify you on the status of your refund after inspecting the item.

How I can find my VIN/Chassis number?

The car's vehicle identification number (VIN) is the identifying code for a SPECIFIC automobile. The VIN serves as the car's fingerprint, as no two vehicles in operation have the same VIN. A VIN is composed of 17 characters (digits and capital letters) that act as a unique identifier for the vehicle. A VIN displays the car's unique features, specifications and manufacturer. The VIN can be used to track recalls, registrations, warranty claims, thefts and insurance coverage.

WHAT IF THE VIN IS NOT 17 CHARACTERS LONG?

Double-check to make sure that you have the right VIN and have copied it down correctly. Once you have verified that the VIN is definitely less than 17 characters, the VIN is most likely from a pre-1981 vehicle. Prior to 1981, VINs varied in length from 11 to 17 characters.

WHERE CAN I FIND THE VIN?

The VIN can be found by looking at the dashboard on the driver's side of the vehicle. The easiest way to view it is to stand outside the vehicle on the driver's side and look at the corner of the dashboard where it meets the windshield. If the VIN cannot be found there, open the driver's side door and look at the door post (where the door latches when it is closed). It is likely that the VIN will also be displayed in this location.
