Driveshaft Upgrades
For those pushing their S550 Mustang to its limits, particularly with enhanced grip and significant power increases, there’s a genuine concern regarding the durability of specific components. While adequate for factory specifications, the standard Ford driveshaft/prop shaft cannot handle these heightened demands. There’s not only the risk of component failure but, in extreme cases, the potential for catastrophic damage to the vehicle – including the possibility of it flipping over. A driveshaft that withstands excessive power is crucial for safety and optimal performance. But to be even safer, we recommend a driveshaft safety loop to prevent any risk of extreme damage.
