World Premiere: Deathbolt & Feral40 – The Ultimate 15mm Adapter!
Riders, get ready…. Freakynuts just unleashed the Deathbolt 15mm Adapter for RockShox Boxxer and the Feral40 15mm Adapter for Fox 40—and this is pure downhill punk.

Forget messing around with loose adapters or a thin axle inside a sleeve. This beast is one solid piece. Straightforward, no compromise, no bullshit.
Install it in seconds, and turn your ride into a 15mm wheel downhill monster. Faster, simpler, and stronger than anything else out there.

And here’s the crazy part: our solid 15mm axle isn’t just tough—it beats a standard 20mm axle in strength tests. What more could you want? Riders are stoked, mechanics are speechless, and rumor has it even the army wants these as tank piercers.

Why this is insane:
One-piece design – no loose parts, no sleeves
Lightning-fast, one-tool installation
CNC-machined from 7075 aircraft-grade aluminum
Ultra-strong, lightweight, built to shred hard
Turns your fork into a downhill monster in seconds

This isn’t just an adapter. It’s your ticket to bigger drops, harder landings, and total trail domination.

Stop waiting. Stop thinking. Upgrade your ride now.
