Plan production & delivery

Production starts after payment; transit follows dispatch. Read Shipping & Delivery before ordering, and confirm timing with us if you need the sills for a specific date.

Questions before ordering

How do I check whether the dimensions will work?

Compare the dimensions in the chosen product listing with the usable flat area on your vehicle. A matching model name is not a size check. If measurements are missing or unclear, send us the product link, your measurements and a photo before ordering.

How do I choose the right generation?

Confirm your vehicle’s model, generation and model year, then compare the year and trim information in the listing. This collection groups the available designs; check the generation stated on each product.

Where can I get help with installation?

The requirements depend on the kit and mounting surface. If the product instructions leave a question about your vehicle, send us a photo of the sill area for advice before installation.
