If you’re looking to beef up your ride’s drivetrain, you’ve got to check out the Richmond Gear 3.42 Ring and Pinion set. This isn’t just any gear set; it’s built for those who appreciate a solid performance upgrade. Richmond Gear has been in the game for decades, and their products have seen the winner’s circle at events like the Daytona 500. So, you know they mean business.

This particular set is designed specifically for GM 7.5, GM 7.6 IFS, and GM 7.625 differentials, making it a great fit for a range of classic and modern vehicles, from the Buick Regal to the Chevrolet Camaro. The 3.42 gear ratio strikes a nice balance for street and strip applications, giving you that extra torque without sacrificing too much on the highway.

Let’s get into the nitty-gritty. You’re looking at a ring gear made from tough 8620 steel, which means it’s built to handle some serious abuse. The ring gear has a diameter of 7.5 inches and comes with 41 teeth, while the pinion gear has 12 teeth and a 1.438-inch diameter shaft with 27 splines. That’s some solid engineering right there.

Installation is straightforward, too, with a cover bolt quantity of 10 and a ring gear bolt quantity of 10, so you won’t be fumbling around with a million fasteners. Just make sure your differential carrier break is 3.23 ratio or higher, and you’re good to go.

Now, if you’re concerned about fitment, this gear set is compatible with a bunch of models, including:

  • Buick Apollo (1973-1975)
  • Chevrolet Blazer (1987-2001)
  • GMC Jimmy (1983-2005)
  • Oldsmobile Cutlass (1977-1981)
  • Pontiac Firebird (1977-2002)

Whether you’re cruising around town or hitting the track, this Richmond Gear set will give you the reliability and performance you need. It’s not just about the numbers; it’s about how it feels behind the wheel. So, if you’re ready to upgrade, this is a solid choice that’s backed by years of racing pedigree.

Notes:

  • For GM 7.5"/7.625" (10 Bolt)
  • 3.42 Ratio
  • Requires a 3.23 and Numerically Higher Ratio Carrier
