What Is Axle Ratio?Last Updated February 5, 2020 | Alison Smith
In basic terms, axle ratio is the drive shaft or output shaft revolutions needed to spin the axle one complete turn. Axle ratio can be used in reference to either the front or rear axles, depending on if the vehicle is front wheel drive, rear wheel drive, all-wheel drive, or four-wheel drive. Several factors are affected by the axle ratio of a vehicle including fuel economy, towing capacity, and top speed. More specifically, the ratio is the number of teeth on the axle’s ring gear in relation to the pinion gear on the driveshaft.
A differential is a critical component of every vehicle, but what exactly is a locking differential? While similar to a standard, or open, differential, a diff lock allows equal amounts of torque to reach both wheels at the same time rather than spin at different speeds. Locking differentials are great for off-roading, especially in tricky situations where you may need a little extra traction.
Sway bars, often referred to as stabilizer bars or anti-roll bars, are featured in many vehicles to help prevent vehicle body roll and lean, especially when cornering. Sway bars are attached to the chassis, helping connect both the right side and left side in order to stabilize the vehicle while still permitting each side’s suspension to move on its own. While sway bars are great for certain driving applications such as on the track or on the trail, the purpose that each sway bar serves will be quite different depending on the scenario. Let’s look at Jeep sway bars and how they improve performance off-roading and on the street.
Transfer cases are found in all four-wheel-drive or all-wheel-drive vehicles and help distribute power to both the front and rear wheels. Transfer cases for four-wheel-drive vehicles, including Jeep transfer cases, typically come with two different gear settings — high and low — for low-speed rock crawling and situations where more traction is needed. Connected the rear of the transmission, the transfer case directs power through the driveshafts to both ends of the vehicle.
Although most beadlock wheels seen on the street only imitate the functional version, there are benefits to having beadlock wheels, especially in off-roading or racing applications. What are beadlock wheels, you ask? Great question! Beadlock wheels secure the bead of a tire to the wheel to lock it in place. While friction and air pressure typically keep the tire properly aligned with the wheel, beadlocks attach to the bead of the tire in order to prevent the bead from separating, basically “locking” the tire in place.
