Fox Factory HP Shock Pump 350PSI Shock Pump w/Swivel Head - High

Our review of the Fox Factory HP Shock Pump 350PSI finds it best for riders and mechanics who need precise, high-pressure inflation for modern shocks and dropper posts. The single biggest reason to buy is clear: it reaches up to 350PSI, covering the full range of many shock platforms while remaining compact and durable enough for trail use or workshop benches. The pump blends a sturdy 6063 aluminum barrel and handle with a stainless swivel head so users can access tight linkages that foil standard pump heads.

Key Features

• 350PSI maximum: Allows the pump to inflate high-pressure shocks and seat posts that require pressures up to the stated limit.
• Stainless swivel head: The UP-SA swivel head provides access to shocks around complicated frame linkages without forcing awkward angles.
• 6063 aluminum construction: The machined barrel and handle give a lightweight but solid-feeling tool you can use regularly without excess flex.
• Micro-adjust air-bleeder: The 2-3 PSI bleed valve lets riders fine-tune pressure in small increments for precise sag and ride tuning.
• Foldable hose: A short, foldable hose makes the pump compact for storage while still offering a bit of reach to the valve.

Who It's For

This pump is aimed at mountain bikers, bike mechanics, and serious cyclists who need a compact, reliable tool that reaches pressures most low-volume shock pumps cannot. If you run DPS or DPX2 style shocks that approach 350PSI, the pump's range and micro-adjust bleeder make it especially useful.

Riders who only make casual pressure adjustments under 200 psi or prefer a built-in frame-mounted meter and integrated high-volume features may find simpler pumps more convenient. Also, those who need an electronic gauge or ultra-low-effort inflation for very high pressures could look at powered inflation solutions instead.

Pros & Cons

Pros

• Reaches up to 350PSI, covering the pressure window for many modern shocks and posts.
• Durable stainless swivel head makes it easy to attach in tight or awkward locations.
• Compact, well-built 6063 aluminum barrel and foldable hose improve portability and longevity.
• Micro-adjust 2-3 PSI bleeder for precise pressure tuning and better sag setup.

Cons

• Some users report it becomes hard to pump above about 200 PSI, so expect more effort at the top end.
• Analog gauge provides readings but lacks the clarity of a larger digital display for quick checks.
