This is also a really good shock for a 2017-2019 Trek Fuel EX (except the 9.9 mounting hardware is kind of a pain). The dpx2 unlocked my 9.8. The total length is correct, the shock tune is good for the Fuel, and the 55 mm stroke length is just fine. There's another few mm of travel but there's still plenty of clearance with the frame. It pairs really nice if the fork has been extended to 140.
