Yukon Gear & Axle YGK2321 Ring & Pinion Gear Set with Positraction and Master Install Kit

The Yukon Gear & Axle YGK2321 is a complete rear differential re-gear package that bundles a high-performance ring and pinion gear set, a Positraction limited-slip unit, and a full master installation kit into a single, convenient part number. Designed for enthusiasts who want to upgrade gear ratios, improve traction, or restore worn drivetrain components, this all-inclusive kit eliminates the guesswork of sourcing individual components.

What's Included:

• Ring & Pinion Gear Set — Precision-manufactured to exacting tolerances that exceed OEM specifications, engineered for quiet operation and long service life
• Positraction Limited-Slip Unit — Fully rebuildable clutch-style limited-slip differential unit for improved traction and power delivery to both rear wheels
• Master Installation Hardware — All required bearings, seals, shims, and small parts needed to fully re-gear the rear differential

Key Features:

• Manufactured using advanced heat-treating techniques and state-of-the-art design processes
• Built to tolerances that meet or exceed original equipment specifications
• Positraction unit requires limited-slip friction modifier additive in differential fluid to minimize chatter
• Backed by Yukon's Y.E.S. (Yukon Extended Service) Plan — a comprehensive lifetime no-questions-asked warranty for as long as you own the vehicle
• Proven performance in demanding off-road environments including King of the Hammers and Moab trail use

The YGK2321 simplifies the re-gear process by delivering everything needed in one kit, saving time and ensuring proper component compatibility. Both rear tires must be of equal height for the Positraction unit to function correctly and avoid premature wear.
