Performance Tool 1/2 in Drive 9‑Pin GM Axle Nut Socket, Deep Chrome‑Moly for 2011+ 10.5/11.5 Full‑Floating Axles

The Performance Tool W83006 is a deep, 1/2" drive 9‑pin axle nut socket built to remove and reinstall 9‑slot rear axle lock nuts on 2011 and newer heavy‑duty GM C/K2500 and C/K3500 trucks without chisels or makeshift adapters.

If you work on full‑floating rear axles, this specialty socket streamlines axle nut service by engaging the 9‑slot pattern directly and fitting standard 1/2" drive ratchets or breaker bars. Constructed from chrome‑molybdenum steel, it delivers the reach and durability needed to clear surrounding suspension parts while applying the torque required for stubborn nuts. The W83006 is engineered specifically for GM 10.5" and 11.5" full‑floating axles produced 2011 and later.

How does this socket make axle nut removal easier?

The W83006 is shaped to align with the nine‑slot GM axle nut pattern so you can spin the nut off without resorting to chisels, hammers, or welded adapters. Its deep design keeps the tool clear of brake and suspension components while the 1/2" drive socket accepts common breaker bars and impact‑style handles for reliable leverage.

• Direct 9‑slot engagement reduces slippage and rounding of the nut
• Deep well reaches recessed axle nuts on full‑floating setups
• Fits standard 1/2" drive tools—no special adapters required
• Chrome‑moly construction resists wear under heavy torque

Will this fit my GM truck and axle size?

This socket was designed for heavy‑duty GM C/K2500 and C/K3500 trucks from model year 2011 onward that use 10.5" or 11.5" full‑floating rear axles with a nine‑slot lock nut. It is not a universal axle tool—verify your axle nut has the 9‑slot profile before purchase.

• Compatible: 2011+ GM C/K2500 and C/K3500 heavy‑duty trucks
• Axle types: 10.5" and 11.5" full‑floating rear axles
• Not compatible: single‑drive half axles or other non‑9‑slot nuts
• Confirm: visually inspect nut pattern before use

What tools pair with the W83006 for safe use?

The socket accepts a 1/2" drive, so common workshop tools like breaker bars, torque wrenches, and impact wrenches are suitable partners depending on the task. Use a breaker bar or long ratchet for controlled loosening, and an impact wrench only if the job and fastener condition warrant it.

• Use 1/2" drive breaker bars or ratchets for manual leverage
• Impact wrenches may be used cautiously if necessary
• Torque wrenches verify final installation torque when reassembling
• Penetrating oil and safety eyewear recommended for stubborn hardware

How durable is the socket and what maintenance does it need?

Made from chrome molybdenum steel, the W83006 is built for repeated high‑torque use and resists deformation. After use, wipe clean of grease and grit, lightly oil to prevent corrosion, and store in a dry toolbox to preserve fit and finish.

• Material: chrome‑molybdenum for strength and fatigue resistance
• Aftercare: clean, dry, and lightly lubricate before storage
• Avoid excessive hammering or off‑axis impact to prolong life
• Inspect the drive and slot engagement surfaces periodically

Who is this for: The Performance Tool W83006 is aimed at professional mechanics, fleet technicians, and DIY truck owners who maintain 2011 and newer heavy‑duty GM C/K2500 or C/K3500 trucks with 10.5" or 11.5" full‑floating rear axles. If you service GM rear axles regularly and want a purpose‑built socket to remove 9‑slot axle nuts cleanly and efficiently, this tool eliminates improvised methods and keeps common 1/2" drive tools in your workflow.
