Fox Racing Shocks 981-44-401-L Factory Race External Bypass Piggyback Shock - 4.4x14 4-Tube Left

The Fox Racing Shocks 981-44-401-L is a Factory Race Series 4.4-inch bore, 14-inch travel external bypass piggyback shock designed for serious off-road racing and high-performance trail use. This is the left-side shock and features Fox's proven externally adjustable, position-sensitive damping architecture built to deliver race-winning performance and long-term durability.

The 4.4 Series steps up from the 4.0 platform with a larger body diameter for increased oil volume and improved heat dissipation, making it ideal for demanding desert racing, rock crawling, and high-speed off-road applications. The four-tube external bypass design provides precise, position-sensitive damping control throughout the shock's travel range — delivering a compliant, predictable ride in normal off-road conditions while aggressively resisting harsh bottom-outs and top-outs.

Key Features:

• 4.4" bore x 14" travel — large-volume body for superior heat management and consistent damping performance
• Dual-coated steel body with proprietary Fox Grey Cerakote® protective ceramic coating over zinc-plated basecoat for outstanding corrosion resistance and durability
• 17-4 H900 hard chrome-plated stainless steel shaft — resists rock chip damage and corrosion far better than standard chrome shafts
• All-new Gen 3 clicker adjuster for 1" bypass tubes — delivers 25% more adjustment range over the previous generation with fewer parts for improved serviceability
• Revised Gen 2 clicker adjuster for 3/4" bypass tubes — externally adjustable, tool-free tuning of position-sensitive damping zones
• PTFE-lined, heat-treated alloy steel spherical bearings for smooth, quiet shock movement
• Dual Speed Compression (DSC) adjusters — allow tool-free high and low-speed compression adjustment for customizable damping
• Machined 7075 aluminum reservoir mounting hardware with offset bottom shock mounts for secure, precise fitment
• Aluminum finned remote piggyback reservoir with recirculating reservoir bridge for enhanced heat dissipation and consistent oil temperature
• JM92 MIL-SPEC oil developed specifically for off-road racing applications
• Black anodized CNC-machined aluminum components with color-coded adjuster seals for easy identification of compression, rebound, and gold valve circuits
• Owner-serviceable and rebuildable — custom valving options available
• Left-side specific — mirrored design; pair with 981-44-401-R for a complete set

Built on the same platform as Fox's race-winning Trophy Truck shocks, the Factory Race 4.4 External Bypass series represents the pinnacle of Fox's off-road suspension technology. It is fully rebuildable and owner-serviceable, with custom valving available to tailor damping to your specific application and driving style.
