USA Standard 8.2in Buick / Oldsmobile / Pontiac 3.55 Ratio Ring & Pinion Set

If you're looking to replace the ring and pinion gears in your classic Buick, Oldsmobile, or Pontiac with an 8.2-inch rear axle, this USA Standard set is a solid option. These gears are designed to meet or exceed OEM specifications, giving you reliable performance for your drivetrain. The 3.55 ratio is a popular choice for a balance between off-the-line acceleration and comfortable highway cruising, making it a versatile upgrade for many applications.

USA Standard Gear puts these sets through rigorous in-house quality evaluations. This means they're checked for proper dimensions, material integrity, and fitment before they ever leave the factory. This attention to detail helps ensure you get a well-built set that will perform as expected. They are designed as a general OE replacement, meaning they're intended to work with your existing differential housing and setup without requiring extensive modifications, provided your axle housing is the correct 8.2-inch GM BOP type.

This set is compatible with a wide range of vehicles from the mid-60s to early-70s, including models like the Buick Skylark, Oldsmobile Cutlass, and Pontiac Firebird. When installing a new ring and pinion, it's crucial to follow the manufacturer's recommended setup procedures, which typically involve proper gear pattern checking and break-in. This ensures the longevity and quiet operation of your new gears.
