- Our Rigid Axle, Detroit Truetrac style, "HELL" limited-slip positraction 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:

  • Fully Machined, Forged Steel Case
  • 3x2 Spiral Gears for Progressive and Variable Traction
  • 100% Maintenance Free
  • 2 Year / 100,000 Mile Warranty
  • Uses LM102949 & LM102911 Bearings & Races for the 8.5" Housing (2.891" Race OD) or LM603049 & LM603012 for the GM 8.6" Housing (3.062" Race OD)
  • Non-Synthetic GL-5 Gear Oil Recommended
  • Synthetic Oils and Friction Modifier Not Recommended

- Rigid Axle's OE Dry 2-Cut and aftermarket ring and pinion gear sets are made from heat treated 8620 steel. Our OE Dry 2-Cut ring and pinions are made using a two-cut, face hobbed manufacturing process. The advantage to running a 2-Cut gear is how quiet they operate. If you want a guaranteed quiet gear, upgrade to our Dry 2-Cut gear set! When these gears are set up properly and rolled with gear marking compound, the pattern will show up slanted. Our aftermarket gear set is made using a five-cut, face milled manufacturing process. Once set up correctly, this will give a square contact pattern on the drive and coast side of each tooth. We are proud of our ring and pinion lines, and you will be too!
