Axles

Quick types of carriers in the differentials

1. Open Differential

  • Terminology: Standard, Open, Open Carrier, “Peg-leg” (slang for single-wheel traction).
  • How it works: Uses spider gears to allow the left and right wheels to spin at different speeds, which is necessary for turning corners. It always splits torque 50/50.
  • Pros/Cons: Smooth operation, low maintenance. Drawback: If one wheel loses traction, all power goes to that wheel, leaving you stuck (the “one-tire fire”).
  • Main Use Case: Daily drivers, economy cars, non-performance commuter vehicles. 

2. Limited-Slip Differential (LSD/Posi)

  • Terminology: Posi, LSD, Clutch-type, Helical gear LSD.
  • How it works: Handles like an open differential during normal driving, but when one wheel spins, the carrier transfers a portion of the torque to the wheel with traction.
  • Types:
    • Clutch-Style: Uses clutch packs and springs to bind the axle shafts together when they spin at different speeds.
    • Gear-Drive/Helical: Uses worm gears to detect torque loss and send it to the wheel with grip. Requires no special additives and never wears out.
  • Main Use Case: Performance cars, performance trucks, street-strip cars.

3. Locking Differential (Locker)

  • Terminology: Locker, Manual Locker, Automatic Locker, Air Locker, E-Locker (Electronic), Selectable Locker.
  • How it works: Mechanically binds both axles together so they must spin at the same speed, regardless of traction. Provides 100% torque to both wheels.
  • Types:
    • Selectable (Air/Electric): The driver engages the lock via a button or switch. It operates as an open differential until locked.
    • Automatic: Uses a mechanical ratcheting mechanism to unlock only when turning on pavement. It is usually locked under acceleration.
    • Lunchbox Locker: A type of locker that replaces just the spider gears inside an open carrier.
  • Main Use Case: Everything. Off-road, rock crawling, drag racing and normal city driving.

4. Spool / Welded Differential / Lincoln Locker

  • Full Spool, Mini Spool, Welded Diff.
  • Not technically a differential. A spool is a solid piece that ties both axle shafts together forever, 100% of the time. A welded differential is an open differential with the spider gears welded together.
  • Pros/Cons: Maximum strength and traction. Drawback: Terrible street manners, difficult turning, high stress on axle parts.
  • Main Use Case: Drag racing only, dedicated off-road mud boggers, drift cars.
