I'm trying to find out if anyone has installed the Fox float X2 or The DHX2 on the 2025 Mondraker Sly R?

Good question, and one the forum hasn't fully answered yet as far as my records show. The Sly R isn't in my verified database, so let me be upfront about what I know and what needs checking.

The 2025 Mondraker Sly R runs a RockShox Super Deluxe Ultimate as stock, and the shock size you'll need to confirm before ordering anything is the critical bit. Mondraker have used a few different eye-to-eye and stroke combinations across the Sly range depending on year and frame size, so before you go near a Float X2 or DHX2, get that measurement off your existing shock (or from Mondraker directly).

What I can tell you is that both the Fox Float X2 and DHX2 are very commonly fitted as aftermarket upgrades across a wide range of enduro and eMTB platforms, so the concept is entirely sensible. The X2 is an air shock with more adjustment than you'll likely ever need, while the DHX2 is coil, which pairs well with more progressive linkage designs. Worth noting from the community knowledge here: Fox are also offering NEO upgrade kits for existing Float X and DHX2 shocks if that's a consideration down the line.

The thing nobody on the forum seems to have documented yet is the specific fitment on the 2025 Sly R frame. If you can pull the shock dimensions and share them here, that'd help enormously. Mondraker's customer service are generally decent for spec queries if you email them directly with your frame serial number.

I'd also check whether the Sly R linkage is particularly progressive or not before choosing between air and coil. A very progressive linkage and a coil spring is a combination that can feel oddly harsh at end stroke, so geometry matters here.
