Hey there! If you're diving into the world of gear ratios, let me tell you about the USA Standard ring and pinion sets. These aren't just any gears; they're built for confidence and reliability, especially when you're tackling that install. USA Standard Gear has put together a solid lineup that fits a range of applications, including some that are a bit tougher to find.

• Designed specifically for GM 8.25 inch IFS models from 2013 and earlier
• Features an 8.25-inch ring gear diameter
• Comes with a 30 spline pinion—solid and dependable
• Includes 10 ring gear bolts for a secure fit
• Offers a 4.56 gear ratio, perfect for enhancing torque and acceleration

You can rest easy with a one-year warranty against manufacturing defects. It's nice to know that the folks at USA Standard stand behind their stuff.

Technical Notes:
If you're working with a 2010 GM 8.25 IFS front end that has the factory 3.08 gear, keep in mind you'll need a new carrier when switching ratios. For those looking at gears of 3.42 and up, you’ll need to grab a YC G26018131 case to go along with it. Just a heads up: the deck height with the 3.08 ratio is 1.780”, while with 3.42 and higher, it’s 1.920”.

Fits the following models:
- Cadillac Escalade (1999-2000 & 2002-2020)
- Chevrolet Avalanche (2007-2013)
- Chevrolet Avalanche 1500 (2002-2006)
- Chevrolet Avalanche 2500 (2002-2006)
- Chevrolet Blazer (1992-1994)
- Chevrolet C/K 1500 (1988-1999)
- Chevrolet C/K 2500 (1988-1995)
- Chevrolet Silverado 1500 (1999-2017)
- Chevrolet Suburban (1992-2020)
- Chevrolet Tahoe (1995-2020)
- GMC C/K 1500 (1988-1999)
- GMC C/K 2500 (1988-1995)
