Yukon Ring & Pinion Gear Set – Chrysler 9.25" Front
YUKYG C9.25R-411R
The Yukon Chrysler 9.25" Front Axle Ring & Pinion Gear Set is designed for front axle re-gearing, ratio correction after tire upgrades, and complete differential rebuilds. Ring and pinion ratio changes are one of the most effective ways to improve drivetrain performance, directly impacting torque delivery, crawl capability, towing response, and transmission behavior.
This gear set is an excellent choice for trucks running larger tires, heavier accessories, towing loads, or frequent off-road use and helps restore lost power caused by oversized tires while improving throttle response and low-speed control.
Includes:
- Ring gear
- Matching pinion gear
Sold as a matched gear set
Installation kit, bearings, shims, seals, and carrier components sold separately unless noted.

Tech Insight
A 4.11 ratio is commonly selected for 35" tire builds, towing applications, and vehicles needing more low-speed pulling power. It increases driveshaft revolutions per axle turn, multiplying torque to the tires while raising cruising RPM.
Because this is a front axle gear set, it must match the rear axle ratio exactly in 4WD systems. Incorrect ratio pairing can cause severe drivetrain bind and transfer case damage.
Proper setup requires accurate pinion depth, backlash, preload, and tooth contact pattern adjustment to ensure quiet operation and long service life.
