The OE plastic connector is a frequent failure point due to brittleness and cracking caused by repeated thermal cycling and hydrolysis. Hydrolysis, the breakdown of plastic or rubber by water exposure, weakens the structure over time, leading to failure. To combat these issues, Rein’s upgraded connectors are constructed from high-strength aluminum, eliminating the vulnerabilities of plastic connectors and ensuring long-term durability.
