Spartan Helical Gear Positraction For Jeep Dana 30 Front 27 Spline | 3.73 & UP

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.

• 27 spline, 3.73-and-up ratio
• Fits Dana 30 front differentials
• Forged 8620 steel alloy case and internals for superior durability
• Maintenance free, no worry performance
• Recommended gear oil: Non-synthetic 80W-90 GL-5
• Smooth engagement and linear traction
• Use of friction modifiers not recommended

Technical Notes: Fits 3.73 and Up gear Ratio, (also 3.45 & Up Ratio on 2018+ Jeep Wrangler JL D30)

This unit would be comparable to an Eaton Truetrac or similar Torsen Style limited slip differentials with the main difference being the number of gears(pinions) internally.
