At the time of this write-up, the highest performance shocks/struts available for the Explorer platform are the Bilstein B6 model line.  It is a step up from the Bilstein B4, which is their OEM replacement line.

I finally got them installed after a nearly 6 month wait for one last front strut.  Seems there was a shortage nationwide as deliveries from Germany had been delayed, likely due to the early COVID restrictions.  I had ordered them through Summit mid-December of 2019 and got the last strut (PN: 22-266620) beginning of June 2020, but seems that everyone was out at the time.

• Bilstein B6 22-266637 Front, driver’s side
• Bilstein B6 22-266620 Front, passenger’s side
• Bilstein B6 24-266664 Rear, both sides

Anyway, it’s a pretty straight forward installation so didn’t get too many photos.  I started with the rears.

Removed top bolt of rear strut assembly.  Just have to pop of the plastic pieces on the top of the rear wheel “hump” of the interior.  And this will be exposed:

Purchased all new rubber pieces from Ford so that everything going in would be brand new:

Installation is just reverse of removal.

Fronts were pretty simple.  I have a spring compressor that that helps.  I purchased brand new hats from Ford for the fronts as well as the rubber spring seat.  Just wanted everything to go in new.
