SKU CH-W7PK-6PCVW

  • 3/8" drive fits standard sockets and ratchets
  • Black phosphate finish resists corrosion
  • Spring-loaded ball locks socket securely
  • Notched design ensures safe ratchet engagement

Drive Extension for Tight Spaces

This 3/8" drive extension adds six inches of reach for fasteners buried in cramped engine bays or suspension assemblies. It is built for professional technicians and serious DIYers who need reliable access without resorting to universal joints or improvised adaptors. The impact-rated construction withstands repeated hammer blows from cordless or pneumatic tools.

Secure Locking Mechanism

Spring-loaded ball retention grips any 3/8" drive socket firmly while precision notches engage the ratchet square to prevent accidental release under vibration. The black phosphate coating resists corrosion from road salt, brake fluid and shop chemicals. California Proposition 65 warnings apply because the finish contains listed substances.

Reach and Clearance Limits

Six inches of extra length clears most brake calipers, intake plenums and subframe obstacles encountered on passenger cars and light trucks. The fixed length cannot telescope or collapse, so extremely deep recesses may still require a longer bar or a flex-head ratchet. Users needing more than six inches of straight reach should select a different extension.

Highlights

  • 6" extension reaches fasteners in tight spaces
