Spicer Specialty Axles for On_Off and Off-Highway Specialty Applications: Condensed Specifications - Manual (Page 7)

Spicer  Steer Drive Axles
Single Reduction – Available with Controlled Traction Differential. The CTD
is a driver controlled torque biasing wheel differential which directs more power
to the wheel with the best traction. CTD is ideal for applications where ice, snow,
gravel or slippery road conditions are present.
Dual Range – Deep reduction on low range for maximum power and traction.
Planetary Double Reduction – Rough terrain and off-highway applications.
