Product Details

Reach the bolt you can't see. The Avichome Offset Extension 2.0 uses an internal chain drive to carry your ratchet's turn around obstacles, so you can loosen and tighten fasteners tucked behind frames, brackets and engine parts โ€“ without tearing half the car apart.

Why you'll love it

  • Offset chain drive โ€“ turn the bolt from the far end of the bar, up where there is room to swing
  • Zero swing arc at the bolt โ€“ no room needed around the fastener itself
  • Works with the sockets you own โ€“ 1/4", 3/8" and 1/2" square-drive adapters included
  • Turns both ways โ€“ flip your ratchet to tighten or loosen

Specifications

  • Length: 15.4" (39 cm)
  • Drive adapters: 1/4", 3/8", 1/2" square drive
  • Includes: 1/4" socket
  • Material: alloy / chrome-vanadium steel, chrome-plated anti-rust finish
  • Mechanism: sealed internal steel chain drive
  • Max torque: 72 Nยทm (53 ftยทlb)

In the box

  • 1 ร— Offset extension bar
  • 3 ร— Square-drive adapters (1/4", 3/8", 1/2")
  • 1 ร— 1/4" socket

Works with hand ratchets and impact tools on low settings within its 72 Nยทm (53 ftยทlb) rating. It solves reach, not rust โ€“ free seized bolts with penetrating oil first.

Zero swing arc at the bolt. 15.4" of reach. 1/4" ยท 3/8" ยท 1/2" adapters. Save your knuckles.

Why make it harder than it has to be?

Awkward angles?

No more twisting your wrist for a quarter turn. Spin the ratchet where there is room to swing.

Tight spots & hidden bolts?

The chain drive reaches fasteners tucked behind frames, brackets and hoses โ€“ no teardown needed.

Short on time?

Get the job done faster and safer, with your hands kept clear of hot or sharp parts.

How It Works

1

Spin the open end

Run your ratchet or impact driver on the end that sits in the clear, where there is room to swing.

2

The chain carries the turn

A hardened roller chain relays the rotation around the obstruction without slipping.

3

The buried bolt turns

The fastener you could not reach breaks loose while your hands stay in the open.

Why the others fail

Offset Extension 2.0

โœ• Flex-head ratchet

The head collapses sideways as soon as you put weight on it.

โœ• Swivel or U-joint

It bends at the joint and the socket walks off โ€“ that is how bolts get rounded.

โœ• Stubby ratchet

A few degrees of swing at a time. Slow, and it still may not break loose.

โœ“ Avichome Offset Extension

Nothing bends. The chain turns inside a rigid bar, so your force goes straight to the bolt.

Offset Extension 2.0

Dominate Every Tight Corner

Rigid all-metal bar

Alloy steel body with a chrome-plated, anti-rust finish โ€“ no flex, no plastic gears.

Zero swing arc

You need no room around the bolt โ€“ all the turning happens at the other end.

Fits your sockets

1/4", 3/8" and 1/2" square-drive adapters plus a 1/4" socket in the box.

Turns both ways

Flip your ratchet to tighten or loosen โ€“ the chain drives in either direction.

Offset Extension 2.0

Where it earns its place

Engine bays

Alternator, starter, manifold and bracket bolts tucked behind hoses.

Suspension & exhaust

Hardware hidden behind frames and heat shields.

Boats & marine

Riser, starter and pump bolts down by the transom and flywheel.

Mowers & machinery

Small-engine and equipment bolts with no room to swing.

This tool solves reach, not rust. On seized or corroded bolts, use penetrating oil first.

Used it on a Fendt. Those engine bays are a maze. Avic navigated it like it was designed for exactly this. Because it kind of was.

Used this on a diesel inboard during a refit. Half the bolts in that engine are in stupid places. Avic got all of them. Worth every penny.

Finally got the starter out on my F150. Been putting that job off for two months because I knew it was going to be a nightmare. Avic had it done in 45 minutes. Genuinely stunned.

Questions? Weโ€™ve got answers.

Will it fit in my tight spot?

If the thin end of the bar plus your socket can sit on the bolt, it will work โ€“ you turn it from the other end, where there is room to swing a ratchet.

Will it work with the sockets I already have?

Yes. It comes with 1/4", 3/8" and 1/2" square-drive adapters and a 1/4" socket.

Can I use it with an impact wrench?

Yes, on low settings and within its 72 Nยทm (53 ftยทlb) rating. Do not use it to hammer loose seized bolts โ€“ free stuck bolts with penetrating oil first.

Does it work in both directions?

Yes. Flip your ratchet to tighten or loosen.

How long is it?

The bar is 15.4" (39 cm) long, giving you plenty of offset to reach past obstacles.

What if it does not work for me?

Unused items can be returned within 14 days โ€“ email support@avichome.com and we will send a return label. Defects are always covered.
