Will fitting Rocker Retainers affect my car's factory warranty?Updated 19 minutes ago

It depends on your car maker. Our kits are fitted inside the engine, so if your car is still under its factory warranty, the dealer may look closely at any engine claim made after they're installed. How a claim is handled is up to your car maker and the laws where you live, so we can't tell you how yours will respond.

Before you fit our parts

• Ask your dealer how they'd treat an engine or valvetrain claim with our parts installed, and get the answer in writing if you can.
• Have the parts fitted by a qualified tradesperson and keep the invoice.
• Keep your service history up to date.

Our warranty covers our parts, not your engine or your car's factory warranty. See What does your warranty cover?
