There are a few certainties that are true for all car enthusiasts. First, we might not all like the same brand of car manufacturer, but our loyalty is usually steadfast. It’s typically a genetic thing – if your dad was a Chevy guy, chances are you are too – it’s a family tradition. Next is the fact that we all care about the parts we use when building our cars. Let’s face it, it takes a lot of hard work to get the money required to buy that next piece of the puzzle. For that reason, buying inferior parts is not an option. The folks at Moser Engineering are of the same mindset, as the words “inferior products” are not something that fit within their vocabulary. It’s their family tradition.


Made in the USA means something to Moser Engineering, and that’s why they work closely with US Gear.

That mindset is more than adequately relayed as you watch the above video. As you are intently watching, you will have the opportunity to hear what Jeff Anderson has to say about the Moser philosophy of using quality, American-made products like those from US Gear. “It’s nice to partner with companies that value that logo. Also, that know, made in the USA means something.”


If you’re working on a 12-bolt rearend, the video not only serves as proof of Moser’s commitment to products like those from US Gear, but they also dive into an installation that is sure to explain what goes on during an in-house rearend assembly in a performance rearend.


The process begins with a short description about what is included in the installation kit. This is the same high-quality kit that is available over the counter for the home-do-it-yourselfer. The video also talks about what makes the Lightning-series gears a definite performance must-have.


Isotropic Superfinishing (ISF) is a process that not only delivers an unparalleled, highly-polished look, it also generates a non-directional, low Ra surface.

Not only is the Lightning-series, high-performance gear set made in the USA, but it undergoes a unique treatment process after machining known as Isotropic Superfinishing (ISF) that creates a truly top-notch gear. This treatment delivers an unparalleled, highly-polished look, and it also generates a non-directional, low Ra surface. In case you were wondering, Ra is the smoothness measurement of the surface.


While the polished finish creates the eye candy appearance, it’s vitally important to note the ISF process does more than simply polish the gears. The process delivers several advantages over traditional finishing processes like polishing, coating, or even cryogenics. ISF consists of vibratory finishing method which creates the optimum surface roughness (Ra smoothness) by removing stress risers produced during the manufacturing process. The smooth, uniform finish created by ISF not only looks good, but it promotes increased retention of lubrication and aides in heat transfer.


The installation portion of the video explains the tools you’ll need to accomplish a gear install. For instance, most of the tools that are required, will be readily available in the home enthusiast’s toolbox, but some specialty tools will be needed.

If you’re not familiar with some of the processes of gear installation, you’ll be happy to know that many are outlined in the video. Take for instance the setting of gear backlash. If you’re not sure what it is, or how a proper backlash is achieved, the video does an excellent job of visually explaining it.

If you have ever had a rearend rebuilt, was gear noise an issue afterward? If a gearset is properly installed and you are still experiencing a noisy rear, this could be caused by Noise Vibration Harshness (NVH). To keep it simple, noise is an unwanted sound, vibration is an oscillation that is typically felt (not heard), and harshness generally describes the severity and discomfort associated with the unwanted sound and vibrations.

Jeff explains how the Lightning gears avoid that scenario. “Something that we’ve noticed when we use US gearsets in our rearends, is that we don’t have the complaints of noise. The NVH value of a rearend is critical to a manufacturer like ourselves.”


If you’ve never built a rearend before, the video is a great tutorial, explaining the process.

As Jeff describes, a complete rearend could cost anywhere from $1,000 and up. If you’re spending your hard-earned money, you definitely don’t want inferior parts, and the manufacturer doesn’t want to worry about the quality of their finished product. After all, it is a family tradition.

So, sit back and enjoy this three-minute video and find out how Moser creates race and accolade-winning rearends with the help of American-made products like those from US Gear.
