The Detroit Truetrac was the first type limited slip differential in the industry. The patented design of parallel axis planetary helical gears provide a quiet, automatic splitting of torque. Power transfer goes literally unnoticed by the driver, even in front wheel drive axles! The Truetrac performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant.

• Better Traction : Limits wheel spin-out and improves handling
• Any Conditions : Wet, muddy, icy or loose terrain; automatically transfer power to the wheel with the highest traction
• Maintenance Free : Requires no special lubrication or friction modifiers
