Yukon Gear 11.5in Chrysler & GM Helical Gear Type Positraction

Yukon gear-type helical limited slip differentials know how to put the power down. They use floating helical-cut worm gears that lock the torque down when acceleration or wheel slippage occurs, transferring torque to the tire with the best traction in a smooth progressive manner as torque is withheld from the tire that is slipping. Since gear teeth not clutch packs transfers the torque these LSDs are a high-performance low-maintenance proposition there are no clutch discs to wear and require replacement. Yukon gear-type helical LSDs use floating helical-cut worm gears that lock the torque down when wheel slippage occurs, transferring torque to the tire with the best traction in a smooth progressive manner.

• Fits GM And Chrysler 11.5 in.
• Fits GM and Chrysler 11.5"
• 12 bolt ring gear
• 30 spline

Put power to the ground with the Yukon Gear & Axle PC11.5-HELIC helical gear-type limited slip differential. Designed for GM and Chrysler 11.5-inch axles, this performance differential uses floating helical-cut worm gears to manage torque when acceleration or wheel slip occurs. Torque is transferred smoothly to the tire with the best traction while reducing power delivery to the slipping tire, helping improve traction and control in demanding driving conditions.
Unlike clutch-type limited slip differentials, the Yukon Gear & Axle PC11.5-HELIC transfers torque through precision gear teeth rather than clutch packs. This design eliminates clutch discs that can wear out and require replacement, making the unit a durable, low-maintenance upgrade for high-performance street, towing, off-road, and work applications. Its progressive torque biasing action helps maintain predictable operation without the abrupt engagement commonly associated with some locking differentials.
The Yukon Gear & Axle PC11.5-HELIC features a 12-bolt ring gear configuration and 30-spline compatibility. It is engineered for select GM and Chrysler applications, including the 2003 Dodge Ram 2500 Van, 2010 GMC Sierra 2500 HD, 2010 GMC Sierra 3500 HD, and 2010 Chevrolet Silverado 2500 HD. Verify axle specifications and vehicle fitment before installation to ensure proper compatibility.
