The new Husky air tool line is built to industrial standards for the professional user providing more power, less noise and longer life. This new Husky 3/8 in. Reaction Less Ratchet features low weight housing with rubberized handle overmold. The unique built-in impact chamber provides reaction less operation and allows the tool to produce 80 ft.-lb. of torque. Internal silencing greatly reduces tool noise and the convenient forward/reverse switch in the ratchet head for quick and easy directional changes. Designed for removing and installing fasteners during auto/recreational vehicle/garden equipment service and repair. Particularly good for hard-to-reach high torque fasteners, and work in confined areas where the reaction less design eliminates risk of finger/hand trapping.

Rated 4.4 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by Well worth the money Not an 80 ft lbs ratchet as stated. But still powerful. Pretty darn fast too. Not 600 rpm, but at least 400 rpms, Helps you fly through work. Featherable, and fast. Yes there are stronger air ratchets out there. But not for $100. which makes it a great value. As for durability not sure as of yet. February 18, 2015
Rated 2.0 out of 5.0 by Not even close to the best air ratchet Well I have gone through two of these and both did work however the trigger/valve mechanism is terrible and the torque of 80 ftb. is only at 90psi. which I would expect except that that pressure is not that high for very long so the torque drops very fast at the first couple of raps of the ratchet. It might be good at loosening a bolt that is not to tight. It could break in after at time, don' know. The reactionless function works great if that is real important. I just don't think it is worth a hundred bucks. I have also just purchased a Sioux and a used Mac 3/8 air ratchets and they are fantastic although not reactionless.. Harold April 8, 2015
Rated 5.0 out of 5.0 by Great Air Ratchet Used for a job in replacing a suspension system. Worked great as compared to the 40# model. November 12, 2014
Rated 5.0 out of 5.0 by Excellent air ratchet Having owned several other 3/8" air ratchets over decades, this one is definitely the best. The advertised torque output is accurate - if not slightly understated. The operation is smooth and it feels good in my hands. Socket retention is excellent and the controls are easy to use.

Rated 4.0 out of 5.0 by REACTIONLESS RATCHET IS A REAL WRIST SAVER This Husky pneumatic ratchet is well built and has a nice weight to size ratio. Very easy to use and works flawlessly for small to medium size bolts on lawnmowers, work shops, and vehicle maintenance. The impact driver type feel of the reactionless function eliminates the quick jerking and wrist twisting you get from an ordinary pneumatic ratchet. February 2, 2014
Rated 5.0 out of 5.0 by Ratchet The reactionless aspect of the ratchet is the best part. Working in tight spaces, having a ratchet that doesn't kick back is a knuckle saver. Its power is another welcomed benefit. It is large but that is expected for its power. July 8, 2014

Rated 5.0 out of 5.0 by Prime this is a great ratchet for the diy-er, good handling of tool,rugged performance and easy on the body. gonna put this guy thru some ringers. thanks husky's August 26, 2014
