If you’re looking to beef up your truck's rear end, the USA Standard Gear ring and pinion set is a solid choice. These guys have a reputation for making reliable parts, and this set is no exception. It’s designed specifically for the GM 10.5-inch 14-bolt trucks, so you know it’s going to fit right without any fuss.

• Fits GM 10.5 Inch 14-bolt trucks
• 10.50 Inch ring gear diameter
• 30 spline pinion for robust performance
• 12 ring gear bolts for added strength
• 5.38 gear ratio—perfect for those who need more torque
• Thick gear compatible with 4.10 and down carriers

This setup is great if you’re looking to improve your truck’s towing capacity or just want to feel that extra pull when you hit the gas. The 5.38 ratio is ideal for off-roading or hauling heavy loads, giving you that low-end grunt you crave. Plus, with the thick gear design, you won’t have to worry about it giving out on you when you need it most.

And hey, it comes with a one-year warranty against manufacturer defects, so you can install it with a bit of peace of mind.
