When it comes to drive train components, Motive Gear really stands out. These guys know their stuff, and if you’re serious about performance—whether you’re hitting the trails or cruising the streets—you’ll want to check out their differential ring and pinion options. They’ve got a massive selection of gear ratios that fit just about any application you can think of. And let’s be real, you’ll find their parts in the winner's circle at races around the globe. That’s not by accident; it’s because they’ve put in the work to develop top-notch components through years of racing experience.

What You Get

This particular differential ring and pinion is designed for GM 7.2" IFS setups and comes with a 4.56 gear ratio. It’s built to last, made from tough 8620 steel, which means it can handle the stress of both on-road and off-road adventures. With a ring gear diameter of 7.2 inches and a tooth count of 41, you’re looking at a solid piece of engineering. Plus, it features a pinion spline count of 27, which helps with fitment and durability.

Technical Specs

  • Ring Gear Diameter: 7.2 inches
  • Ring Gear Tooth Quantity: 41
  • Pinion Gear Tooth Quantity: 9
  • Pinion Shaft Diameter: 1.315 inches
  • Gear Ratio: 4.56
  • Requires a differential carrier break of 3.42 or higher
  • Fits the front position

Important Notes

This gear set is specifically for GM 7.2" IFS applications. If you’re running a carrier with a ratio lower than 3.42, you’ll need to upgrade that to get this to fit properly. It’s all about making sure you have the right setup for optimal performance.
