What is a TRAC Lok differential?
An available Trac-Lok limited-slip rear differential provides extra torque and grip during slippery, low-traction situations, such as driving over sand, gravel, snow or ice.
Can you do a burnout with a Truetrac?
If one tire breaks traction, the amount of rotation (or spin) is controlled. The torque is then sent to the other tire that still has traction. But yes, a truetrac will do a one wheel burnout if one tire is in water and the other isnt.
What is Trac Loc posi?
Trac-Loc Limited-Slip Posi: The Trac-Loc Limited Slip Differential is designed as a direct replacement for the hard to find expensive OEM unit, or for those enthusiasts desiring to convert to a limited slip. The cone design, along with the applied force, determines the torque transfer capability of the differential.
Is Truetrac good for drag racing?
The TrueTrac is not recommended for drag racing, expecially with a stick car. The helical gear set up in a 8.8 differential does not allow sufficient gear contact surface area to withstand shock loads of repeated clutch dumps with slicks!
Is Posi Trac better?
In a positraction differential, the unit senses which wheel has the greatest traction, when one tire is slipping or stuck, and sends power to that wheel. Positraction is beneficial when road conditions are wet or muddy.
How strong is an Eaton Truetrac?
The Truetrac designs have been produced within a maximum continuous torque range from 2,500 Lb-Ft to 25,000 Lb-Ft.
How does a Truetrac locker work?
The Truetrac operates by transferring power from the spinning wheel to the wheel with the most traction. If one tire breaks traction, the amount of rotation (or spin) is controlled. The torque is then sent to the other tire that still has traction.
What cars came with Positraction?
What cars came with posi traction? GM has offered Positraction rear ends since 1957, and its 8.875-inch 12-bolt Positraction was most popular in Chevrolet passenger cars from 1965 to 1972. Pontiac offered a version of a Positraction unit, called Safe-T-Track, as an option on vehicles including the 1963 Pontiac Tempest.
What is a Trac Lok rear axle gearbox?
Rear axle gearbox, often consisting of a pair of units – main gear and differential. What is Trac Lok differential axle? A differential is a mechanical device that divides the input torque of an input shaft between output shafts, called poles.
What kind of differential does a Detroit truetrac use?
Detroit Truetrac – Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at slightly different speeds for smooth cornering.
What kind of clutch does a truetrac use?
With silky-smooth positive operation and no components to wear out, the Truetrac maintains day-one performance for the life of the unit. Trac-Lok/Posi-Trac – Clutch-type limited-slip (Posi), offered as original equipment in many GM and Ford performance cars, these units rely on clutches (friction plates) to transfer power to the wheels.
How does a truetrac work on a Posi?
However, when accelerating (torque applied), the six helical-gears inside the unit smoothly and quietly engage, applying torque to both rear wheels equally, maximizing traction (think two equal length black stripes). Unlike a traditional clutch-type posi, a Truetrac requires no special oil additive or maintenance.
