ABS Plastic . Glossy Black Finish . Bolt-On Installation

This rear bumper add-on diffuser splitter lip is built for 2020-2025 Corvette C8 Stingray, Z51, and E-Ray models, giving the rear fascia a cleaner, more aggressive finish without altering the factory bumper. It’s molded from high-grade ABS plastic and finished in glossy black, matching the factory-integrated look OE-style trim aims for.
Pre-drilled mounting holes (where applicable) line up with the factory mounting points, so it bolts on without cutting or drilling. A complete hardware kit is included, and every piece is fitment tested for alignment. Professional installation is recommended for the best alignment and finish.
High-quality gloss black ABS plastic for a clean, factory-integrated appearance right out of the box.
Engineered to match OEM design standards for a seamless, factory-equipped appearance.
Designed for the C8 rear bumper with precise mounting points for a correct fit.
Pre-drilled mounting holes align with factory mounting points. No cutting, no drilling, no mods.
Includes all necessary mounting fasteners and an installation guide for the install.
Each piece undergoes fitment testing to check for OEM-level quality and precise alignment.
