Yukon Ring & Pinion Gears front & rear differentials | RANDYS

Yukon Gear & Axle Performance Ring & Pinion

Yukon Gear & Axle high ring & pinions set the industry standard for quality, performance, and durability.

Ring & pinions come in a selection of gear ratios for both front and rear differentials that vary the amount of torque is applied to your tires. This ratio affects off-the-line performance, gas mileage, off-road crawling capabilities and overall drivability. The larger diameter of bigger than stock tires changes the ratio, resulting in lackluster acceleration, poor towing, and labored climbing. Big-tire rigs require larger, deeper gears in a higher numerical ratio to transfer power properly and restore your ride’s stock driving characteristics.

Yukon’s engineers use state-of-the-art design and testing processes, backed by two in-house quality assurance labs, to ensure each gearset meets exacting specifications, for hardness via heat-treating, and torsional strength.

Gear tooth surface finishes on all Yukon ring & pinion gearsets are designed to reduce both friction and heat. This quality provides the performance to withstand the rigors of off-road racing, intense trail runs and racing in heavily modified, high-horsepower vehicles.

All Yukon ring & pinion gearsets come with a one-year warranty against manufacturing defects. Yukon also offers its Y.E.S. Plan for a lifetime, comprehensive, no-questions-asked protection plan covering your gears for as long as you own the vehicle.

To protect your investment, rely on the experts at Yukon Gear and Axle as we describe how to properly break-in your Ring and Pinion gears.

When ever the gear ratio in a differential is changed pinion diameter changes. There are two things that must change in order for the gear ratio to change. First, the gear ratio is determined by the tooth combination. The number of teeth on the ring gear divided by the number of teeth on the pinion (eg: 41/11 = 3.73) equals the gear ratio.  Click to the article to read continue reading.

There are several types of rear ends that use a threaded side adjuster be it a single adjuster or one on both sides of carrier. The most commonly known rears with this type of carrier adjustment are the Chrysler 7.25-8.25-8.75-9.25, Ford 9”, GM 8.25” IFS, Suzuki Samurai, & Toyota. Click on the image to continue reading more.
