Let’s talk downspeeding: how it works

Any on-highway truck you spec today will likely employ downspeeding to some degree. Engine downspeeding is enabled through faster axle ratios that allow the engine to maintain a lower RPM—thus saving fuel—while still providing the necessary power to the axle. Axle ratio is written as a ratio, such as 2.16:1. But what does 2.16:1 mean?

Get your efficiency bearings

When considering axles that boost your efficiency, you’d likely want to extend those efficiency gains out to your wheel end through the spec’ing of high-efficiency bearings for that extra fraction of fuel efficiency gain. While a fraction of a percentage might not seem like a lot for one truck, spread it out across your entire

The downspeeding lowdown

Remember that most modern powertrains utilize some degree of downspeeding. Here’s a quick refresher on downspeeding details.

How the latest axle technology integrates into powertrains

If the engine is the heart of your powertrain and the transmission is the shifting brains behind the operation, then the axle is the muscle, propelling your truck down the highway. While the engine and transmission get much of the spotlight, the axle plays a key role in increasing efficiency—in both proprietary powertrains and those

Let’s talk medium-duty truck tire spec’ing

Medium-duty applications can vary wildly—from pick up and delivery to construction and refuse tasks. The two most important variables to consider are the specific application of the vehicle and weight considerations. Beyond that, gross vehicle weight rating and ride-height requirement, along with durability, traction and climate considerations should all be taken into account. Click here
