USA Standard ring & pinion sets are designed to provide a quality and quiet gear set for OEM replacement. USA Standard uses rigorous in-house quality testing and inspections to ensure products pass dimensional, material and fitment testing. USA Standard gears come in OE and aftermarket ratios, providing a wide variety of product to meet the needs of most any installation: from 1948 to present popular vehicle models. USA Standard gears are designed to exceed OEM specification while providing an affordable drivetrain solution. All USA Standard Ring and Pinion Gear Sets come with a standard one year warranty against manufacturing defects.
I had high hopes for the USA Standard Gear set, but unfortunately, mine arrived with some damaged teeth. It was frustrating, and I had to request a replacement. Hopefully, the next one will be better.

Solid upgrade for my truck
I installed the USA Standard Gear ZG GM9.5 ring and pinion in my Chevy and it's awesome! The gear set is well-made, and I can really feel the difference in performance, especially off-road. Highly recommend it for anyone looking to boost their GM 9.5 differential.

Great performance but tricky install
Once I got the USA Standard ring and pinion installed in my truck's differential, the performance was fantastic! However, I struggled a little with the installation instructions; they could be clearer. Just take your time if you’re a novice.

Decent but took a while to deliver
I received the USA Standard Gear ring and pinion set after a longer wait than I'd hoped for. The product itself is solid, no complaints there, but I was frustrated with how long shipping took. Just be prepared for some delays.

Good quality but slight noise
The gear set works great, just as I expected from USA Standard. Installation was straightforward, but I did notice a bit of whine at higher speeds. It’s not a dealbreaker, but something to keep in mind if you're sensitive to noise. Overall, happy with my purchase!
