Your axles are only as good as what’s turning inside them. For off-road enthusiasts, classic car restorers, and serious 4x4 builders, the ring and pinion gear set is one of the most critical drivetrain components you’ll ever choose.
Get it wrong, and you’ll deal with noise, premature wear, and power loss. Get it right, and every gear change feels smooth, responsive, and built to last. Motive Gear stands out as a leader in the drivetrain components market, setting industry standards for quality and reliability.
Motive Gear has spent decades earning its place among the most trusted names in driveline products. Motive Gear offers the highest quality drivetrain components on the market. From stock daily drivers to full-competition 4x4s and race vehicles, Motive Gear products are engineered to meet or exceed OEM specifications, backed by rigorous in-house quality control that tests every component for strength, tolerance, and hardness.
Motive Gear offers aftermarket ring & pinion gearsets, differential bearing kits, a complete line of transmission and transfer case parts, and axle shafts. Their complete line covers everything from ring-and-pinion sets and differential bearing kits to axle shafts, installation kits, transfer case parts, and lockers.
This guide breaks down what makes Motive Gear ring-and-pinion sets the go-to choice for performance builds, which ratios and configurations fit your vehicle, and how to get the best value when you’re ready to add to cart.
What Is a Ring and Pinion Gear Set?
At its core, a ring and pinion set is the pair of gears inside your differential that transfers power from the driveshaft to the axles. The pinion gear connects to the driveshaft, while the larger ring gear meshes with it to drive the axle shafts, ultimately turning your wheels. High-quality pinions, especially those made from forged steel and manufactured using precision processes such as CNC machining and heat treatment, are critical to durable, reliable ring-and-pinion gear sets.
The gear ratio (such as 4.88:1 or 5.13:1) determines how many times the driveshaft rotates for every single rotation of the axle. A higher ratio means greater torque multiplication, better low-speed pulling power, and improved crawl capability, making it ideal for Jeep builds running larger tires.
Ring pinion sets are engineered for both off-road and street use, offering exceptional durability and performance for a variety of driving conditions. A lower ratio prioritizes top-end speed and fuel efficiency on the highway.
Choosing the right ratio depends on your tire size, transmission, transfer case, and how you drive. Pair the wrong gears with oversized tires, and your engine will constantly feel like it’s working against itself.
Why Motive Gear Products Stand Out
Not all aftermarket ring-and-pinion gears are created equal. Motive Gear's reputation is built on manufacturing precision, and there's a reason their driveline products are trusted by drivers from daily commuters to competitive off-road racers.
Advanced Manufacturing and Quality Control
Every Motive Gear ring and pinion set is produced using advanced manufacturing techniques that deliver consistent tooth geometry. This precision matters more than most buyers realize. Poorly cut gear teeth create excess noise, heat, and wear. Motive Gear's in-house quality control lab uses state-of-the-art equipment to continuously check components for strength, tolerance, and hardness before anything ships.
The result? Gears that mesh cleanly, run quietly, and hold up under demanding conditions. Whether you're crawling boulders on a trail or hauling heavy loads on the highway, the components perform as expected.
Premium Steel Construction
Motive Gear ring gears are constructed from 8620 steel, a premium alloy prized for its surface hardness and core toughness. This material handles the heat generated under load while resisting wear on the gear teeth. It's the same material used in high-performance and OEM applications, and it's a key reason Motive Gear products carry meaningful warranty coverage.
Broad Compatibility Across Vehicles
Motive Gear's product range spans vehicles from the 1940s through the present. Whether you're building out a Jeep Wrangler JL with a Dana 44, restoring a classic Ford with a 9" rear differential, or upgrading a GM axle, Motive Gear has the gears, axles, and components to match. Their complete line of driveline products includes:
- Ring and pinion sets across dozens of gear ratios
- Differential bearing kits and install kits
- Axle shafts for a wide range of applications
- Transfer case parts and lockers
- Chrysler, Ford, Dana, and GM axle fitments
Ring and Pinion Sets for Jeep Wrangler JL (Dana 44 / M210 / M220)
The Jeep Wrangler JL is one of the most popular platforms for gear regearing, and Motive Gear offers multiple ratio options for both the Dana 44/M220 (rear) and Dana 44/M210 (front) axle configurations.
5.13 Ratio, MGR-D44-513JL and MGR-D44-513JLF
The 5.13:1 ratio is a favorite among Wrangler JL owners running 37" to 40" tires. It restores the throttle response and low-range torque that gets lost when you upsize your rubber without regearing.

Installation and What to Buy Alongside Your Ring, Pinion, and Related Parts Set
Motive Gear ring and pinion sets are sold as a set, ring, and pinion gears only. For a complete installation, you'll need to purchase additional components separately. A proper differential rebuild requires:
- Differential bearing kits (carrier bearings, pinion bearings)
- Install kits (pinion seal, crush sleeve, pinion nut, shims)
- Ring gear bolts
- Differential cover gasket
- Differential oil and friction modifier (if running a limited-slip)
Skipping any of these components is a common mistake that leads to premature failure. If you're doing the job right, start with a complete master kit or bearing kit to ensure every component is replaced at the same time. Motive Gear offers bearing kits and installation kits designed to complement their ring-and-pinion sets. Buying matching components from the same manufacturer simplifies compatibility and keeps your warranty intact.
If you're new to differential work, have the gears installed by a professional. Setting proper backlash and pinion depth requires specific tools and experience. An incorrect setup will cause noise, heat buildup, and accelerated wear, regardless of the quality of the gears.
