Stick It!

Welcome to the online home of Auto Gear Equipment Motorsports, where the last company actively designing and improving four-speed manually-shifted gearboxes reveals all.

We believe that ‘driving a stick’ — controlling the torque of a big V8 with foot and hand — is one of those priceless opportunities to give all-conquering technology the finger that, no matter where the car companies go, racers and enthusiasts will continue to demand. That’s why we do it — to make sure you have the chance. And, because, quite honestly, after seventy years in the business, we’re very good at it.

There are five more questions almost everyone asks.

Are Auto Gear ‘Muscle Car’ parts as good as original equipment?

If they were only that good we’d scrap them! Manufacturing advances such as CNC machining, diamond cutting tools, cleaner steels, and better control of heat treatment enable us to do things General Motors could only dream of doing in 1965. There was a saying then — If it’s to print it goes to service, if not, it goes to production. That’s why we don’t ‘blueprint’ any more. It’s no longer necessary.

How are Auto Gear ‘Muscle Car’ parts made?

Manual transmission engineering is a Syracuse tradition older than the automobile; when we can’t answer questions ‘in house’, we routinely tap world-class resources available almost nowhere else in North America. All our gears and shafts and castings are controlled by Auto Gear prints. Which means that we decide when they’re ‘to print’, not our vendors. Furthermore, wherever possible mating parts are sourced with a single vendor so there’s undivided responsibility that they run properly together.

Where are Auto Gear ‘Muscle Car’ parts made?

Today, in a relationship more than a quarter-century old, our four speed gearing is supplied by the Italian firm Euroricambi and their A.M. Gears subsidiary (the near-legendary craftsmen of Antonio Masiero). Castings are poured in the United States and machined either in house (our aluminum), or within an hour’s drive (our steel and iron). Synchronizer rings, bearings, oilseals and small parts are supplied by leading name brand vendors worldwide. For us, quality and performance always trump country of origin. Price is important, but never governs.

Why not bring some or all of your offshore items back to the United States?

We’ve tried. Did you know that, compared to Italy, it actually costs the same or less to make gears in the United States? Pricing’s the problem. You want value for your money, and the American vendors we’ve asked won’t work on internationally competitive margins.

Why don’t you offer a five speed?

For many years, big American V8’s, with their awesome torque and wide power bands, were the envy of the automotive world. And often, what impressed the enthusiasts and engineers was how little the cars they powered needed to shift. When did shifting become more important than driving? We’re not persuaded. More gears are better only when they’re needed, and most of our customers cannot actually use more than four. That said, we agree that some racing or high speed road applications might benefit from five gears properly spaced.

Gearboxes and Gearsets: Configuration and Pricing

Getting you the right gearbox

No doubt about it, selecting the right gearbox for your car is a challenge. We’re proud to be on your candidate list. We also recognize that, with three different duty levels and multiple input, output, gearset and speedometer options configuring one of our four-speeds (or finding the right upgrade gearset) might look as intimidating as doing your taxes.

Fortunately, EZ-Spec can do most of the work for you. Our Applications Wizard, Nathan, will reply with his recommendation.

Everything you need to know for your ride

Can you help me find the right gearset? We didn’t intend to make you dizzy, but with three different duty ratings, eighteen different ratios, input and output options and more, it can happen. Call us, tell us what you have and what you want, and we’ll talk you through the process.

Can you sort out my speedometer drive? No problem, just supply your axle ratio and tire specification.

Can you advise me on interface items like clutches, shifters and axle ratios? Certainly! It all needs to work together! At Auto Gear we see the entire car, not just our gearbox.

Can you ‘superfinish’ gears and shafts? ‘Superfinishing’ is a vibratory polishing process for hardened steel parts that gives them a mirror-like finish as smooth or smoother than the surface of a ground roller bearing. Racers take advantage of superfinishing to reduce friction and eliminate the need to ‘break-in’ new gearboxes. We do it ‘in house’ to support our manufacturing, so we can usually deliver new gears, shafts and shift forks from stock saving you the hassle, waiting, and extra shipping your friends may have encountered elsewhere. And unlike acid-accelerated alternatives like ‘REM’, the water-based process we use is eco-friendly.
