Do these have the notch to lock onto quick release ratchets?

Yes they do, they work good on the couple quick release ratchets I own.

What is the difference between 81200D and 81200?

the set 81200D is the standard 3/8 drive extension bars there is a set 81201 which is the 3/8 wobble extension bars. there is no set 81200 on the gearwrench website

what are the lengths? thanks!

If you scroll don the page on Amazon, you will see the sizes listed: "The KD Tools 4-Piece 3/8-Inch Drive Extension Set includes 1-1/2-inch, 3-inch, 6-inch, and 12-inch extensions."

Will it take 98 foot pounds. Just broke an old one.

I personally would use a half-inch drive 3/8 is a little small for hundred foot pounds

Good product good deal

This is a great product at a great price I do own lots of other extension sets and just personal preference these ones just aren’t my favourite just something to do with the thickness of them and the head of them it’s just a personal preference. honestly it might not even bother some people some people may find there great, there definitely still a good buy.
