Eaton Posi Differentials

The Eaton Posi is the perfect way to control traction in street rods, light duty pickups and everyday drivers. The Eaton Posi prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. The Eaton Posi is fully rebuildable with one of our specially formulated clutch kits.

Muscle cars, hot rods and mild offroad vehicles should look to Eaton’s limited-slip differential for their traction answers. And the fact is, Eaton’s Posi units are virtually bulletproof.

Features:

• Carbon Friction Technology

• Precision-Forged Gears

• Automatic

•Rebuildable

Auburn Ected Locking Differential

The Auburn ECTED Max offers both limited slip and locker modes. An on/off switch is mounted near the driver. In the “off” position it operates in limited slip mode. When the “on” position is selected, the differential operates as a solid axle assembly – the spool/locker performance you desire at the strip or off-road.ECTED Max™ Advantages:

  • ECTED Max gearing is made from aircraft quality, 9310 heat-treated billet steel to make it as tough as nails!
  • ECTED Max can be switched on or off “on the fly,” at any road speed.
  • ECTED Max does not have any shift forks or pins that must be lined up to obtain locker mode.
  • ECTED Max is quiet – say good-bye to noisy lockers!
  • ECTED Max is backed by an industry-leading one-year warranty, just like all Auburn Gear Performance Differentials.
  • ECTED Max is backed by the industry-exclusive program. D-REX = Differential – Replacement EXchange Program.
  • ECTED Max can be used in front axle applications – with or without lockout hubs.
  • ECTED Max is the only selectable locker that offers both limited slip and locker modes. Forget the rest – go with the best!

Important Note: The ECTED Max is not recommended for use in front axles that feature an “Inter-Axle Disconnect.”
