Dinan
Dinan Tension Strut Ball Joint Kit – Front BMW G2x G42
OVERVIEW
An underrated component of a proper driver's suspension, the monoball kit (tension strut ball joint kit in today's terminology) is a remnant of an era when road feel was something desirable and sought after. Dinan restores that visceral connection to the road by replacing the stock rubber bushings in the front thrust arms with precision ball joints housed in machined aluminum housings — delivering responsiveness you can feel, drastically improved steering response, and reduced brake shimmy. Despite the performance gain, these are the quietest bearings on the market: a nylon-lined design keeps operation virtually noise-free, and they're sealed with a rubber boot to keep out dirt and road grime, preventing premature wear for everyday livability.
