The world's premier traction aid, an ARB Air Locker(TM) keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.This Part Fits:

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

A Wonderful Update To A Great Old Reference Book!
Format: Hardcover
It's the Merck Manual! If you know medicine but are aware you don't know EVERYTHING about EVERYTHING! (Few if any do!) This is a wonderful reference. If you have no medical knowledge and think this will make you know what doctors know. Don't waste your money. You have to have a basic understanding for this to be helpful. This is a wonderful update to an old favorite.

The most current and inclusive medical reference available mid-2018.
Format: Hardcover, Format: Hardcover
Here’s the review I wrote for the 19th edition on 2011: I've been getting and using the Merck Manual for over 30 years to answer questions about disease for family and friends (pediatrics through geriatrics) as well as preparing to ask germane questions of physicians responsible for care of family and friends. It is comprehensive in its coverage of the etiology, diagnosis, treatment and prognosis of diseases of the human body and contains the latest research results on the treatment options. It's really not that difficult for the layman to understand the medical terminology and the result is factual understanding of the major aspects of disease which you will NOT get from the standard home health care books from Johns Hopkins, Harvard, Mayo Clinic, the AMA or even the Merck Home Health handbook. And, unlike the Merck Manual, these books directed to the laity do not contain the diagnostic information upon which physicians decide precisely what disease they are presented with. Yes, there will be much superfluous information which you may never use, but, when you want and need the information about a specific disease, here's where you should start your education.
The same holds true for the updated 2018 20th edition. I neglected to mention that this manual also contains a plethora of ancillary information including thorough sections on pediatrics, geriatrics, injuries, bites and stings, patient care, alternative medicine, dietary supplements, rehabilitation, normal test values and even legal issues such as advance directives. Yup, it’s pricey, but it’s always proved to be valuable to me.
