Eaton Posi Differentials

Eaton Posi Differential

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 Gear Limited-Slip Differentials

 

Auburn Gear has been the leader in performance limited-slip differentials for nearly 55 years.

Today, no matter what you drive—dragsters, performance cars, everyday passenger vehicles, light-duty trucks, vans, sport utilities, off-road or recreational vehicles—there is an Auburn Gear performance differential engineered to maximize your vehicle’s tractive capability.

  • Auburn Gear HIGH PERFORMANCE SERIES (HP) Limited-Slip Differentials:

Auburn Gear’s flagship limited-slip differential gives you smooth torque-sensing operation with the correct bias ratios to out perform the competition.

  • Auburn Gear PRO SERIES Limited-Slip Differentials:

Turns your torque up another notch, offering an even higher bias ratio and faster sensing reaction than HP for the very best in controlled power transfer.

  • Auburn Gear RACE SERIES Limited-Slip Differentials:

High Performance limited-slip differential specifically for road racing—a differential case designed to allow the center pin to float along with the axle shafts.
This design feature aids the driver when cornering, so that when the driver is turning, the outside wheel axle shaft will apply a force to the center pin, hence, the pinion gears will firmly seat the inside cone/side gear assembly giving the racer an extremely “tight” rear axle. The greater the G-force the more bite you get! If you are an avid road racer you’ll want this unit.

Auburn Ected Locking Differential

 

Most Auburn ECTED Max models offer both “limited-slip” and “locker” modes. Some of the newer units switch from “Open” to “Lock”

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.”
