Find the Competitive Advantage in a Durable, Lightweight Quick Change Gear 

With the limits on today’s racing engines, it’s hard to find an advantage under the hood. But you can make the most of that horsepower by reducing weight in the driveline. Competition driveshafts and lightweight ring and pinions can reduce rotating mass, making starts quicker and more of that power making it to the rear wheels. But there’s one more place where you can get an advantage: the rear end quick change gears.  

Track Tested 8620 Steel Stands Up to The Competition

High demands are placed on the quick change gears of rear ends but Speedway Motors has found a lightweight answer. Tested in race action for a full season before release, our Premium Lightweight Quick Change Gear Sets are drilled for weight reduction, yet constructed of durable 8620 Alloy steel in a perfect balance of strength and weight. Our lightweight gears are perfect for high-horsepower applications with large tires.  

Less Weight and Reduced Friction Surfaces Means More Power to the Ground 

Less rotating mass means more power goes to the tires. REM finished polished surfaces and crown shaved profile teeth provide better tooth contact which means reduced friction, longer life and cooler running, which not only makes these perfect for the demands of racing, but also make a great complement to a quick-change street setup - the tooth finish and profile make for a quieter running rear-end.

Our Premium Lightweight Quick Change Gear Sets are available in all common sets for any ratio you need. Suitable for 4.11, 4.12 and 4.86 rear ends. Get the most out of your 410 Sprint Car, 305 Sprint Car, 360 Sprint Car, Modified, Open Late Model or Crate Late Model with our award-winning Premium Lightweight Quick Change Gears.
