Dimensions: 63.45mm x 20mm (length x O.D.)

Average unit weight: 116g (4.09 oz)

Rated for 1.000hp

Piston rings 83mm set

Contains 01 complete set for 5 cylinder engine.
Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

About CMD Extreme Pressure lubricants:

When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.

They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!

CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.

        Add this to every DoD Reading List!
        Format: Kindle
        There were so many great excerpts throughout the book that my highlights filled 16 pages in MS Word. This is a must read for all Pentagon personnel, those in operational commands, the acquisition community, and defense industry. Chris' insights as McCain's advisor were invaluable to understand the nuances and competing incentives of the DoD, industry, and Congressional perspectives. "The problem is that America is playing a losing game. Over many decades we have built our military around small numbers of large, expensive, exquisite, heavily manned, and hard to replace platforms that struggle to close the kill chain as one battle network. China, meanwhile, has built large numbers of multi million dollar weapons to find and attack America’s small numbers of exponentially more expensive military platforms." "It requires a sweeping redesign of the American military: from a military built around small numbers of large, expensive, exquisite, heavily manned, and hard to replace platforms to a military built around large numbers of smaller, lower cost, expendable, and highly autonomous machines." "New technologies alone will not save us. We need new thinking — an ambitious effort to reimagine the ends, ways, and means of US military power, as well as the role of our allies in this effort — to succeed in a future world where America’s military superiority will likely erode further if China’s military technological development continues."

        The Real Arms Race
        Format: Kindle
        I am a life-long Democrat, supposed to bristle at the very idea of military spending. Brose's book convinced me the problem is not how much we spend, but what we're spending it on. "Kill chain" is military-speak for the three phases of combat -- figuring out what's going on, deciding what to do about it, and taking effective action. Brose spells out how technology changed all three phases while the Defense Department and its minders in Congress weren't paying attention. The result has been to significantly undermine our military preparedness and, more importantly, the ultimate goal of deterrence. For all the money we're spending, Brose shows how it's mostly on the wrong things, i.e., large, expensive platforms that are only incremental improvements over prior systems designed for different times. He shows how the military-industrial complex, abetted by a Congress invested in the status quo, is arming our military with technology inferior to what you'd find in a modern automobile. The development of the Internet may have been kick-started by the defense department back in the 1960s, but the information revolution that followed largely left the U.S. military behind. Meanwhile, potential adversaries are compensating for relatively lower defense budgets by exploiting emerging technologies that could change the character of war, raising multiple ethical, geo-political, and governance issues. The Kill Chain is compelling, scary, and must-reading for our political leaders and all intelligent voters.

        Well written and thought-out approach to change DoD acquisition
        Format: Hardcover
        I'm a Navy acquisition manager and former Navy officer. I very strongly recommend this book as required reading for Pentagon (especially flag officers and SESs), congressional staffs, defense contractors and those who would be defense contractors, Silicon Valley companies, and everyone who cares about the future of the United States. The author expertly characterizes the current world situation and the issues with DoD acquisition practices. He is not brutal about it, but fair. He explains the background and history behind how we got to where we are, and identifies a path forward. I believe that following the approach recommended is very hard, but very worth while. The author worked for Senator McCain for almost ten years, and it is clear that this book benefits from his experience. My only gripe (and it is a minor one) is that very occasionally the author allows his feelings about Trump to manifest in a negative way. This is often justified, but it shouldn't be so one-sided. Nevertheless, this book is must-read, and deserves five stars.

        Very Educational
        Format: Paperback
        I enjoyed the book. I wish the average American would take more of an interest in these kinds of issues facing the U S in the China sea region of the world.
