YG F8.8R‑411R High‑Performance Gear Set — Ring & Pinion, Ford 8.8″ Reverse Rotation, 4.11 Ratio

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.

Key Features

  • 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. 

Benefits

  • 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.

Product Specs

  • 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) 

Install Difficulty Level

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.

  • 1997‑2024 Ford Expedition 4WD 

  • 1997‑2024 Ford F‑150 4WD 

  • 1997‑1999 Ford F‑250 4WD
