Yukon Gear Spartan Helical LSD Worm Gear Limited Slip Differential, Dana 30 Front 27 Spline SL D30-4-27-LSD

The Spartan Helical LSD’s helical-cut worm gears seamlessly funnel torque to the tire with the best grip. Its 10-pinion design is stronger than 6- or 8-pinion units because it has more points of contact to deliver optimal load distribution.
