Review: Great price for these extensions - These extensions work great with my 1/4" Cordless Impact. Love all the workpro tools I have
Review: Mandatory tool for use with your impact driver - For years, I've been using the shorty adapter set of these that Harbor Fraught sells. They aren't always long enough for the job, so I've been sticking standard socket extensions on the adapters. I had no idea they made these adapters in longer lengths! This set is pretty much perfect. You have 3 sets of the 3 diameters commonly used with sockets (1/4", 3/8", 1/2") and three different lengths. Really like that they come with holders for each set. Keeps them from getting lost in the toolbox. One minor quibble: The first set I received had two 1/4" extensions in the shortest set vs. one each 1/4" and 3/8" inch. It wasn't a return either as it was factory sealed. I returned it and the second set I received was as it should be. Something you may need to watch out for. When you get yours, don't assume all the pieces are fine and chuck'em all in the toolbox. Check them. Definitely worth the money and would buy again.

### ⭐⭐⭐⭐⭐ Quality at an affordable price!
*by E***7 on May 3, 2026*

Bought these before I swapped spark plugs and ignition coils on a 2013 Prius. Can’t beat the price, and the extension length is absolutely amazing, and made it easy to get to the hard reach areas. I did pair this with a swivel, but I still would have been able to do the job with these alone! These are also very durable and quite affordable!!! I put these on my 1/4” impact rated for 250 lb-ft of breakaway torque. They didn’t even break a sweat.
