Eaton Detroit True-Trac 8.8" 31 Spline Limited Slip Differential
NOTE: 2005+ Mustangs Require Axle Spacer Modification
The Detroit Truetrac is a gear to gear limited slip unit that performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant. The limited slip unit responds instantly to torque feedback, anytime, at any speed.
Detroit Truetrac:
* Uses pairs of "Helical" gear sets
* Gears only - no clutch packs.
* Ideal for 4WD front axles or rear axles, as well as 2WD; light trucks, SUV?s, cars.
* Rugged yet smooth and quiet.
* Torque bias ratios of 2.5 to 3.5:1 range.
The Detroit Truetrac, manufactured by Tractech, is the aftermarket?s leading gear type limited slip differential. 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 Detroit Truetrac performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant. The limited slip responds instantly to torque feedback, anytime, at any speed.
Detroit Truetrac?s are engineered for front and rear axles, semi floating (C-clip axles) and transfer cases. Proven design, low cost and effective performance all make the Detroit Truetrac limited slip the choice of professionals and traction enthusiasts everywhere.
Great for off-road, street and strip.
The Detroit Truetrac delivers the traction necessary for drag racing and off-road terrain while not adversely affecting handling on the street.
The Eaton Detroit Truetrac® limited-slip differential is the pioneer in helical gear based traction technology. Wheel spin out is limited by the differential, which employs pinion- and side-gear separation forces to automatically transfer torque to the wheel with the best traction. Mobility, stability and handling are enhanced, and drivers can be confident knowing that up to 3.5 times more torque is being transferred to the high-traction wheel. Operation of the Truetrac® is smooth and quiet, and the unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning a lower overall cost for the customer.
Truetrac® OperationThe Truetrac® operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel encounters a loss of traction, the gear separation forces take effect and transfers torque to the high-traction wheel. The helical-shaped pinion gears continue to mesh with the side gears with increasing force until wheel spin is slowed or completely stopped. When the vehicle exits the low traction situation, the separation forces cease and the differential resumes normal operation.
