Spartan Locker Helical Limited Slip Differential Worm Gear Positraction for Dana 30 Front 27 Spline 3.73 & Up

The Spartan Helical LSD from USA Standard Gear's Spartan Locker brand is designed to enhance the traction capability of your Dana 30 front differential. This helical gear design provides years of maintenance-free service, ensuring smooth engagement and linear traction.

When wheel slippage occurs, the pre-loaded worm gears in the Spartan Helical LSD funnel more power to the tire with the best traction. The 10-pinion USA Standard Gear design has a strength advantage over equivalent 6-pinion or 8-pinion units, with more points of contact and a larger surface contact area for optimal load distribution.

Compared to other limited slip differentials or positraction units, the Spartan Helical LSD offers a smoother operation and requires no maintenance. Built with a forged 8620 chromoly case and stout 8620 chromoly alloy internals, this fully assembled unit is designed for superior durability.

Whether you're navigating through mud, loose gravel, or steep inclines on the trail, or dealing with slippery snow or rain on the road, the Spartan Helical LSD will ensure you have unrivalled traction and supreme confidence in your vehicle.
