Ford tested them to the same durability and longevity standards as regular struts so they’re not going to wear faster than any other strut.You forgot to mention that Ford requires you to buy the PP1 or PP2 packages which start at over $4K then add on the $1695. Durability is a concern so I check out replacement cost for the front struts......yikes! They had better last. My standard GT struts both leaked and blew at 7K which were replaced under warranty so I will be looking at the aftermarket down the road. Running those small metallic particles back and forth through the strut valving must create wear as the miles pile on. What is the expected life of these struts ans shocks?
