Can I return a part after it has been installed?

Generally, installed or used performance parts cannot be returned. We strongly recommend verifying vehicle fitment and inspecting the product before installation.

Can I cancel my order after it has been placed?

We begin processing orders as quickly as possible. If you need to cancel, contact us immediately. Once an order has entered fulfillment, been submitted to a supplier, or shipped, cancellation may no longer be possible.

Will this part fit my vehicle?

Fitment varies by year, make, model, trim, engine, and drivetrain. Use our vehicle fitment information to confirm compatibility. If you're unsure, contact us with your VIN and we'll help verify fitment before you order.

How do I know if this is the right upgrade for my build?

Not every upgrade makes sense for every vehicle or build. Tell us your vehicle, current modifications, and performance goals, and we'll help determine whether this product is a good fit.

Are the products you sell authentic?

Yes. We source products through established manufacturers and authorized distribution channels. We do not sell counterfeit or imitation performance parts.

Is professional installation recommended?

For most performance components, yes. Proper installation is critical for fitment, reliability, and performance. Some products may also require specialized tools, programming, tuning, or additional supporting modifications.
