Moker Fork Cap Socket for Harley Big Twin & Sportster — 1 3/8" (35mm) Hex, Low-Profile CNC with O-Ring

Moker's 1 3/8" (35mm) fork cap socket is a low-profile, CNC-machined tool built to remove and install Harley Big Twin and Sportster hex fork cap nuts quickly and without marking polished surfaces.

Working on fork caps tucked under handlebars can be awkward and time-consuming with generic sockets. This fork cap socket from Moker is shaped to fit the common 1 3/8" (35mm) hex used on many Harley Big Twin and Sportster models, with a compact height and an O-ring insert to protect finishes. The chrome-plated, Cr40 steel construction resists corrosion and holds up to repeated use, while compatibility with a 1/2" drive ratchet makes it easy to add to your existing toolset.

How does this socket make fork cap removal easier?

The socket's low-profile geometry (5/8" high, 9/32" depth) lets you reach fork cap nuts positioned beneath handlebars or other tight clearances. Its 35mm hex fit grips the cap securely to prevent slipping, and the included O-ring cushions polished surfaces to avoid scratches during use.

• 1 3/8" (35mm) hex dimension for direct fit on Harley fork caps
• Compact 5/8" height and 9/32" depth for tight spaces
• O-ring insert protects chrome and polished finishes
• Anti-slip fit reduces rounding and slippage

Will this work with my existing ratchet or handle?

Yes — the Moker fork cap socket accepts a standard 1/2" drive, so you can use it with most ratchets, flex handles, or breaker bars in your garage. That compatibility lets you add leverage or maneuverability without buying specialty adapters.

• 1/2" drive square for common ratchets and handles
• Use with flex handles to reach awkward angles
• Compact design fits under handlebars for easier access
• No special adapters required for most tool sets

What materials and machining quality should I expect?

Moker machines this socket from Cr40 hard material with precision CNC tolerances so the hex pocket aligns snugly with fork cap nuts. The chrome-plated finish enhances corrosion resistance and simplifies cleanup after shop use, while the tight machining reduces slop for repeatable removal and installation.

• CNC-machined for accurate, consistent fit
• Cr40 hardened material for durability under torque
• Chrome plating resists rust and looks professional
• O-ring insertion prevents surface damage to polished caps

Which Harley models and service scenarios is this socket suited for?

This socket is intended for Harley Big Twin and Sportster models that use a 1 3/8" (35mm) hex fork cap nut. It’s ideal for routine maintenance, fork seal service, spring changes, or any job requiring secure removal and refit of fork caps in confined spaces.

• Fits many Harley Big Twin and Sportster fork cap nuts sized 35mm
