Get it done right, the first time with drivetrain parts from USA Standard Gear. From Ring and Pinions to Axles, Installation Kits, Bearings, Seals, and lockers, we have everything you need
I love the performance of this USA Standard gear set, but it took longer to arrive than I expected. Once installed, it really improved the torque in my truck, just wish I didn't have to wait so long. Would buy again, but plan for the delay.

Good quality gears, but tough to install
The ZG-F9-389 ring and pinion gear set seems solid, but I struggled a bit with the installation. The instructions could have been clearer. After some trial and error, it functions well in my Ford 9 differential, but definitely not for the faint of heart!

Rugged and reliable!
Just wanted to say how happy I am with the ZG-F9-389 gear set! Installed it in my Ford 9 differential and it's held up great under heavy loads. The metal feels high quality and I can feel the difference while driving. Very satisfied!

Solid Performance for My Ford 9
I installed the USA Standard Gear ZG-F9-389 in my classic Ford, and it's been working like a charm. The gear set fits perfectly into the differential, and the performance is really impressive. My truck now accelerates with a lot more power!

Decent upgrade for my differential
The USA Standard ZG-F9-389 gear set is a nice upgrade for my Ford 9. It definitely improved the responsiveness of my vehicle. However, I found the initial setup a bit more challenging than I anticipated. Overall, I'm pleased with the results.
