vbaxy Fork Cap Nut Socket 1-3/8in (35mm) Hex for Harley Sportster & Big Twin — Low-Profile CNC with O-Ring Protects Finish

vbaxy's 1-3/8" fork cap nut socket is a low-profile, CNC-machined hex tool made to safely remove and install Harley Sportster and Big Twin fork top nuts.

If you service your own forks or need a reliable tool for periodic maintenance, this socket is built specifically for the 1-3/8" (35mm) hex fork caps found on many Harley-Davidson Sportster and Big Twin models. The hardened construction and precision CNC machining give a snug fit on the nut, while a protective O-ring guards chrome finishes. Its compact height allows use with torque wrenches in tight spaces between the fork top and handlebars.

How does this socket make fork cap nut removal easier?

The socket matches the factory-sized 1-3/8" hex to reduce slippage and rounding of the nut. A tight, accurate fit concentrates torque where it belongs, preventing damage and speeding up tasks like changing fork oil or performing top-cap service.

• Exact 35mm (1-3/8") hex profile for Harley fork top nuts
• CNC-machined for a precise, low-tolerance fit
• Hardened material resists deformation under load
• Low profile allows torque wrench clearance near handlebars

Will this socket protect my fork cap finish?

Yes — the socket incorporates an O-ring that sits between the tool and the top cap to minimize marring on chrome or painted surfaces. The O-ring does not affect torque transfer but provides a soft contact point where the tool touches the visible area of the fork cap.

• Pre-installed O-ring cushions the socket-to-cap interface
• Prevents scratches and scuffs during removal or installation
• O-ring is replaceable if worn from repeated use

Is this tool compatible with my motorcycle and workshop tools?

The vbaxy socket is designed for most Harley-Davidson Sportster and Big Twin models that use a 1-3/8" (35mm) hex fork cap. Its drive size and low profile let you attach a torque wrench or ratchet for controlled tightening and loosening in confined areas.

• Fits Sportster and Big Twin Harley models with 35mm fork cap hex
• Low-profile design accommodates torque wrenches in tight spaces
• Works with standard torque wrench or ratchet drives (check drive size on package)

What makes this socket durable and accurate?

Manufactured from a hard material and finished with CNC precision, the socket resists wear and maintains a reliable fit over repeated jobs. The combination of hardness and accurate machining reduces the chance of rounding the nut or wearing the tool.

• Hardened construction stands up to repeated torque cycles
• CNC-machined hex ensures consistent engagement with the nut
• Low-profile form factor engineered for strength and clearance

Who is this for: This vbaxy 1-3/8" fork cap nut socket is aimed at Harley owners, home mechanics, and professional technicians who perform fork maintenance on Sportster and Big Twin motorcycles. If you need a compact, durable tool that protects visible finishes, fits the factory hex, and works with standard torque wrenches in tight conditions, this socket is a practical addition to your toolkit. It’s especially useful when changing fork oil, replacing seals, or doing top-cap adjustments where a precise, low-profile tool prevents damage and saves time.
