The NASCAR 3C Helmet Kit to Harris IMSA 4C Car Harness Adapter is a specialized adapter designed to bridge the compatibility gap between NASCAR helmet kits and IMSA car harnesses. Key features include a robust construction for durability, high-quality connectors that ensure a secure and reliable connection, and a straightforward plug-and-play design for easy installation. The adapter’s main benefit is that it allows drivers to use their existing NASCAR helmet communication systems with IMSA-configured vehicles, saving the cost and hassle of purchasing new equipment. Its unique selling point is the seamless integration it offers between two different racing communication standards, providing versatility and convenience to drivers who participate in both NASCAR and IMSA racing events.

Adapt your NASCAR helmet kit to an IMSA car harness.

Note: NASCAR helmet kits are common grounded and may not work with all radios. If you are not sure please call.
