We've Got You Covered
We guarantee that all products listed with vehicle compatibility have been designed using manufacturer-matched data, precision moulds, or verified test-fitment on supported models. If the item you receive does not fit the vehicle stated on the product page, we will work with you to resolve the issue with priority.
Before You Order
Please make sure your vehicle matches the exact model, year, body style, and chassis code shown on the product page. Our team is always available to confirm compatibility if you are unsure.
If There's an Issue
Contact us within 14 days with photographic evidence of the fitment issue, including proof that the product was installed by a qualified professional following the correct procedure. We will provide a replacement or solution in line with our fitment guarantee process.
Our Promise
In the rare event a product does not fit your compatible vehicle, and the correct installation procedure has been followed by a qualified professional, we will fully support you. We'll cover the return shipping and provide either a replacement product or a full refund.
Exclusions
Custom-specification products (bespoke items built to your own specification) are excluded from the fitment guarantee. Standard made-to-order parts are fully covered.
Warranty
All Twenty Two Tuning and EXL Design products come with a 1-year warranty against manufacturing defects. Merchandise (clothing, accessories) is covered for 6 months.

Custom-specification products (bespoke, built to your own specification) are not covered by warranty.
If a manufacturing defect is confirmed, we will repair or replace the product free of charge.
Not Covered
Accidents, improper installation, external factors, normal wear and tear, shipping costs, labour costs for removal or reinstallation, and any consequential loss or damage resulting from the defect.
Making a Claim
To make a warranty claim, you will need to provide: your order number, evidence of professional installation, proof that the issue is a manufacturing defect (not customer damage or misuse), and proof of purchase from Twenty Two Tuning.

Receiving Your Order: Inspect items before signing. Do not accept damaged goods, as we cannot cover return shipping costs once accepted.
