Spartan Helical LSD worm gear limited slip positraction for Dana 30, front
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.
