Standard shipping takes 5-7 business days. Express shipping is available for 2-3 day delivery. All orders are processed within 24 hours.
We offer a 30-day return policy on all products. Items must be unused and in original packaging. Free return shipping is included for defective items.
Fitment details are clearly listed in the product title and within the dedicated “Fitment” tab on every product page. This section provides all compatibility information, including supported years, makes, and models. If you’re still unsure, don’t hesitate to reach out — our support team will be happy to confirm before you order.
In almost all cases, no — upgrading with Rennsieger parts won’t void your warranty. Laws like the Magnuson-Moss Warranty Act (in the U.S.) and similar consumer-protection rules in Canada prevent manufacturers from canceling your coverage just because you used aftermarket parts. A dealer can only deny a claim if they can prove the part itself directly caused the problem, and even then it only affects that specific system — not the entire vehicle. Since Rennsieger DRLs and upgrades are plug-and-play, reversible, and designed to work with OEM systems, warranty concerns are very rare.
All parts come with a manufacturer warranty ranging from 1-3 years. Extended warranty options are available at checkout. Warranty details are listed on each product page.
Our support team is available Monday-Friday, 9AM-6PM EST. Reach us via live chat, email, or phone. Average response time is under 2 hours.
