Our team at RDS has analyzed hundreds of aftermarket components to bring you this definitive list based on our extensive experience in automotive reverse engineering.
What Exactly Is Automotive Reverse Engineering?
Before diving into our top picks, let’s clarify what we mean by “reverse engineered” car parts.
Reverse engineering in the automotive sector involves taking an existing component, analyzing its design, materials, and functionality, then recreating it—often with improvements in durability, performance, or cost. This process typically involves 3D scanning the original part, creating precise 3D models, and then manufacturing using modern techniques like 3D printing or traditional manufacturing methods.
According to the Society of Automotive Engineers (SAE), properly reverse engineered components can meet or exceed OEM specifications when created with precision engineering processes. The National Institute of Standards and Technology (NIST) has even developed guidelines for evaluating the quality of reverse engineered components to ensure they meet industrial standards.
