Where this product is used

Ko-Ken extension bars extend the reach of a socket drive between a ratchet or wrench and the socket, allowing fasteners to be accessed in deep recesses or behind components.

• Reaching fasteners recessed below engine and component surfaces beyond socket depth
• Providing clearance between a ratchet handle and obstructions near the fastener location
• Combining with universal joints for offset and angled fastener access in confined engine bays

Key specifications

Selecting the right option

Select by drive size and length. Short extensions (25–75mm) provide clearance; medium (100–200mm) reach recessed fasteners; long (250–500mm) access deep wells. Multiple extensions can be combined. Wobble extensions suit angled access but reduce precision — use straight extensions where torque accuracy is required.
