Lisle Pro Shear Socket 2-3/8" 1/2"-Drive for Chevy/GMC DRW Hubs, Hardened Black Oxide

The Lisle 31620 Pro Shear Socket is a hardened 2-3/8" 1/2"-drive tool made to remove and install the circular hub nut on 2021 and newer Chevrolet Silverado and GMC Sierra dual rear wheel (DRW) full-floating axles.

Built for professional technicians and DIY mechanics who service newer Chevrolet and GMC DRW trucks, this socket is designed to engage the four-pin shear-style hub nut found on 11-1/2" and 12" dual rear wheel axle hubs. The socket’s internal pin engagement pattern matches the circular shear nut used on those full-floating hubs, providing a secure fit for controlled removal and installation. The tool is heat-treated for strength and finished in black oxide for corrosion resistance and reduced glare in the shop.

What vehicles and hub types does this socket fit?

This 2-3/8" O.D. socket is intended for 2021 and newer Chevrolet Silverado and GMC Sierra models equipped with 11-1/2" or 12" dual rear wheel full-floating axle hubs. It may also fit other vehicles that use a 2-3/8" I.D. axle nut or a compatible O.D. spindle pattern.

• Specifically matches the four-pin circular hub nut on certain GM DRW trucks.
• May be compatible with other makes if the axle nut dimensions align (2-3/8" I.D.).
• Designed for full-floating hub applications with shear-style nuts.

How durable and safe is the Lisle 31620 for repeated use?

The socket is hardened and heat-treated for durability under shop conditions, and it includes a black oxide finish to resist rust and surface wear. It’s made for controlled torque application via a 1/2" drive ratchet or breaker bar; however, it is not designed for impact wrenches.

• Hardened steel construction for long life during hub service.
• Black oxide finish reduces corrosion and glare.
• 1/2" drive size fits standard hand tools—do not use with impact tools.

How do I use this socket for hub nut removal and installation?

Position the socket so the internal pin pattern engages the hub nut’s circular profile, then apply steady torque with a 1/2" drive ratchet or breaker bar to remove or install the nut. Take care to confirm the nut type and size before beginning, and follow vehicle manufacturer torque and service procedures when reinstalling the hub nut.

• Seat the socket fully on the circular hub nut so the pins engage securely.
• Use a 1/2" drive ratchet or breaker bar for controlled torque application.
• Confirm vehicle-specific torque specs and do not substitute impact tools.

Will this socket replace a full hub tool set?

This Pro Shear Socket is a specialist service piece intended specifically for 2-3/8" shear-style hub nuts; it’s not a universal hub-puller or bearing press. For comprehensive hub service you may still need additional tools such as pullers, presses, seal drivers, or spindle adapters depending on the job.

• Excellent as a dedicated nut socket for compatible shear-style hubs.
• Not a substitute for bearing presses, pullers, or other hub-service equipment.
• Pairs well with standard 1/2" drive hand tools in a professional toolbox.

Who is this for: The Lisle 31620 Pro Shear Socket is tailored for professional mechanics, fleet technicians, and knowledgeable DIYers working on 2021-and-newer Chevrolet Silverado and GMC Sierra dual rear wheel trucks with full-floating hubs. If you frequently service DRW axle hubs or need a durable, correctly sized socket for shear-style hub nuts, this specialized tool simplifies nut removal and installation while protecting the nut and surrounding components when used with proper hand tools.
