If you're diving into the world of performance and looking to upgrade your drivetrain, you can't go wrong with Richmond Gear. These folks know their stuff when it comes to making high-quality, heavy-duty drivetrain parts. I mean, they've been around long enough to have a solid reputation, and their products have even seen victory at places like the Daytona 500 and U.S. Nationals. So, yeah, they’re kind of a big deal in the racing scene.

Let’s talk specifics. This is a 4.33 gear ratio setup, perfect for those who want a little extra kick without going overboard. It’s designed for the GM 8.875 Car differential, and it’s built tough with a 9310 steel ring gear that can handle some serious torque. You’ve got a pinion shaft diameter of 1.625 inches and a 30-spline count, which means it’s ready to take on whatever you throw at it. Plus, with 39 teeth on the ring gear, you’ll notice a difference in how your car responds on the road or track.

Now, if you’re worried about fitment, Richmond’s got you covered. This setup is compatible with a range of classic rides, including:

  • Buick Centurion (1971-1972)
  • Chevrolet Camaro (1967-1972)
  • Pontiac GTO (1970-1972)
  • And many more!

It's worth noting that this gear set works best with a differential carrier break of 3.90 ratio or higher, so keep that in mind if you’re planning your build. And with 12 cover bolts and 12 ring gear bolts, you can trust that this setup is going to stay put, even under hard driving conditions. If you're looking to get a bit more aggressive with your stance, just remember that it might affect your tire fitment, so double-check your clearance before you dive in.

In short, if you’re serious about performance and want a product that’s proven on the track, Richmond Gear is definitely worth considering. They’re built for those who appreciate the finer points of driving and want to feel that connection between the pedal and the pavement.

Notes:

  • For GM 8.875" (12 Bolt)
  • 4.33 Ratio
  • Pro Gear
  • Requires a 4.10 and Numerically Higher Ratio Carrier
