Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that applies to all companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels that are known to cause cancer, birth defects or other reproductive harm. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a “right-to-know” law. Businesses are required to provide warnings to comply with Proposition 65. These warnings are required to be in place for all products offered for sale in California.
There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.
To comply with the requirements of Proposition 65, this warning is present on all products sold by MPT.

This high‑performance ring and pinion gear set, part number YG F8.8R‑411R, is engineered for serious Ford 8.8″ reverse rotation applications. Yukon Gear & Axle applied state‑of‑the‑art design, advanced heat‑treating, precision machining, and rigorous quality testing to deliver gears that stand up to high torque demands, big tires, towing abuse, and off‑road conditions. It’s perfect for anyone upgrading from stock ratios, building up their front axle, or trying to tame power losses and driveline strain. With a 4.11 ratio, this gear set restores pull, helps maintain drivability under load, and improves off‑the‑line acceleration without sacrificing too much highway speed. Backed by Yukon’s YES Plan for long‑term peace of mind, it’s a reliable investment in performance and durability.
Built for reverse rotation applications in Ford 8.8″ front differentials.
4.11 gear ratio restores torque and improves acceleration under load.
Large 8.80″ ring gear diameter with 10 ring gear bolts ensures strength and stability.
High‑splined pinion (28 spline per some sources, others list 30 spline depending on front differential design) for improved strength and engagement.
Manufactured using advanced heat treatment and premium steel to resist wear, maintain geometry under load, and reduce friction/heat buildup.
Enhanced traction and pull power, especially useful when upgrading to larger tires or carrying heavier loads.
Keeps driveline temperatures and stresses down under hard use, helping preserve component life.
A smoother, quieter operation compared with poorly matched or worn gears, thanks to precision tooth finish.
Better overall performance feel both off‑road and on‑road—less bogging, more consistent power delivery.
Cover‑your‑back protection: comes with Yukon’s YES (“Yukon Extended Service”) Plan — a lifetime, no‑questions‑asked protection plan for as long as you own the vehicle.
Gear ratio: 4.11
Ring gear diameter: 8.80″
Pinion spline count: 28 spline (some sources list 30 spline depending on variant)
Number of ring gear bolts: 10
Material: Premium steel, heat‑treated and precision machined
Warranty: 1 year manufacturer’s warranty against defects; optional Yukon YES Plan provides lifetime coverage for how long the owner retains the vehicle.
Weight: approximately 19.8 lbs for the complete set (ring + pinion)
Installation difficulty is moderate. With proper tools and basic differential knowledge, it should take about 4 hours for a front axle swap, assuming clean housing and standard setup. Precise setup of pinion depth, backlash, and bearing preload is needed for noise‑free and reliable operation. Yukon’s gear set is factory‑style design, which helps reduce trial and error.
Fits front Ford 8.8″ reverse‑rotation differential applications. Compatible with:
1997‑2024 Ford Expedition 4WD
1997‑2024 Ford F‑150 4WD
1997‑1999 Ford F‑250 4WD
1998‑2014 Lincoln Navigator 4WD
2006‑2008 Lincoln Mark LT 4WD
