Get Your Powerband Back After Tire Upgrades

When you throw on a set of bigger tires, it doesn’t take long to feel the hit in throttle response and low-end torque. The Yukon YGGM9.25-513R Ring & Pinion Set is the perfect fix for that. With a steep 5.13 gear ratio, this setup helps bring your powerband back into the sweet spot, especially if you're running a lifted GM HD truck. You'll feel stronger takeoffs, smoother acceleration, and way better control when towing or crawling through tough terrain. Yukon builds these gear sets to handle serious abuse, using high-grade steel and a surface finish that fights friction and heat. Whether you're chasing more performance off-road or simply want to restore drivability on the street, this gear set delivers without compromise. Plus, with a lifetime warranty that follows the truck, you can push your build with total confidence.

Designed For The Demands Of Heavier Builds

The Yukon YGGM9.25-513R Ring & Pinion Set is built for GM 9.25" IFS front differentials and uses a reverse rotation design made specifically for front axle applications. It features a 30 spline pinion and 12-bolt ring gear, both precision machined from premium-grade steel for maximum strength and long-term durability. The 5.13 gear ratio is ideal for rigs that have been upgraded with oversized tires or used in towing and off-road environments where torque matters most. Yukon's advanced surface finishing process reduces friction between gear teeth, helping control heat buildup and ensuring smoother engagement during heavy-duty use. These gears are manufactured to tight OEM-level tolerances, which means installation is straightforward when paired with the correct setup tools. For Dodge 9.25" front axles using a factory carrier, a ring gear spacer is required. This set is a reliable, high-performance upgrade for 1988-2015 GM 2500HD and 3500HD trucks built to handle more.
