Package Includes:

(1) Front Axle Helical Style Limited Slip Differential

- Our Rigid Axle, Detroit Truetrac style, "HELL" limited-slip differential unit uses 3x2 spiral gears for progressive and variable traction. This unit acts like a standard open carrier under normal driving conditions making it unobtrusive. Once a tire looses traction, or the terrain changes, the helical cut gears mesh together transferring torque to the high traction tire. Once traction on both sides resumes, the carrier goes back to normal operation. The carrier case is forged steel for strength and reliability. Since this unit does not have clutches and steels, it is completely maintenance free! Rigid Axle's helical-gear style limited slip posi is the perfect choice for daily drivers, weekend warriors, towing, basic off-road use, and street/strip applications. See below for some key features and tech specifications:

  • Fits Front Dana 30 Axle Only
  • For Use with 27 Spline Axles
  • Fully Machined, Forged Steel Case
  • 3x2 Spiral Gears for Progressive and Variable Traction
