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

When wheel slippage occurs, the Spartan Helical LSD's pre-loaded worm gears funnel more power to the tire with the best traction. This 10-pinion design has a strength advantage over an equivalently sized 6-pinion or 8-pinion unit because it has more points of contact and more surface contact area to deliver optimal load distribution. Built tough, the Spartan Helical LSD is a fully assembled unit featuring a forged 8620 chromoly case and stout 8620 chromoly alloy internals for superior durability.
