Ring and pinion gears are hypoid gears that help your engine transmit power to your wheels. They shift the transmission rotation 90 degrees from the driveshaft to the axle shafts to spin the wheels. Moreover, ring and pinion gears help regulate the rotation speed of the transmission into a more controlled wheel axle speed.

What are the types of ring & pinion gears available?

Ring and pinion gear setups can be categorized into three main kinds: hunting, non-hunting, or partial hunting gear sets. Hunting gear sets have teeth that meet all ring gear teeth. Meanwhile, non-hunting gears have teeth touching the same gear tooth or teeth repeatedly. Partial hunting gears use teeth that meet some of the ring gear teeth, then move to another set.

What ring & pinion do I need?

The Mopar ring and pinion set your vehicle needs depends on several factors. When choosing new differential gears, you should check if the rear-end type of your ride has a conventional or a banjo-style setup. Other factors to consider when getting the right rings and pinions include your differential carrier series that distributes power between wheels, your preferred gear style, and what you’ll use your car for.

How do I tell if a ring & pinion is bad?

Faulty ring and pinion gear sets often produce a clunking sound every few feet as you drive. Incorrect installation can also result in damaged ring and pinion gears. If you’ve set these components the wrong way, they’ll make a humming noise and accelerate the wear and tear on the teeth of the gears.

How much do new ring & pinion gears cost?

New Mopar ring and pinion gears can cost between $100 to $500. How much you’ll pay for these parts depends on gear ratio, warranty, kit inclusions, and other factors. If you’re hiring a mechanic to replace your ring and pinion gear set, service rates can range from $400 to $600, depending on the auto shop or mechanic.
