The Truetrac is a helical gear limited slip differential, not a “locker”. 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 by transferring the lost traction to the higher traction wheel.
The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Maintenance-free, it features smooth, automatic operation in forward and reverse. Its versatility makes Detroit Truetrac the ideal traction solution for almost any type of vehicle.
Is a Detroit Truetrac a posi?
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.
The Truetrac designs have been produced within a maximum continuous torque range from 2,500 Lb-Ft to 25,000 Lb-Ft. Increased capacity can be accomplished by larger gears and more pinion sets.
How does a Truetrac locker work? – Related Questions
Does Truetrac need additive?
Do I need friction additive/modifier? A quality petroleum/mineral based oil works best in the Truetrac units. We do not recommend synthetic oil. Friction additive/modifier is not required.
Do Detroit lockers make noise?
When I step on and off the gas pedal, I hear the unit make a “clunking” noise. Why? This happens because Eaton Detroit Lockers have “backlash” or “slack” between the drive and driven teeth and you will hear this in everyday use going through corners and when transitioning from drive to coast.
How much is a Truetrac diff?
PRICE: $1,173.70
The Truetrac’s proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well.
How does Eaton posi work?
The Eaton Posi limited slip differential (also know as Positraction) prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases.
Who makes Truetrac differentials?
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque.
What is a helical limited-slip differential?
The limited-slip differential enhances performance driving for a more exhilarating experience. The Feature: Generally found only on high-powered vehicles, the limited-slip differential minimizes front-wheel slippage, improves steering precision and allows the driver to accelerate out of a corner sooner.
Limited slip differentials are suitable for most driving conditions. This differential’s purpose is to make sure you have the ability to drive under normal conditions without any mishaps. However, selectable lockers make conquering extreme driving conditions possible!
Is it better to have a limited slip or locking differential?
An automatic locking differential can unlock and allow the inside wheel to rotate freely, but only when power is limited. The limited slip differential will allow some slipping between the two side gears, this allows both wheels to get equal traction even though one is spinning faster than the other.
Is a rear locking diff or limited slip better?
Lockers produce 100% lock-up where all the power is directed to both tires all the time when the unit is engaged. Lockers are tougher. Limited slips direct torque to both tires and when slippage occurs the unit directs torque to the tire with the best traction. LSDs do not generate 100% lock-up.
Is Positraction same as locking differential?
`LOCKING DIFFERENTIAL’ IS SAME AS POSI-TRACTION ON YOUR TRUCK.
Which differential locker is best?
For vehicles with open differentials, a rear locker is by far the more popular choice, as it’s more suitable to a diverse range of off-roading situations. “If the vehicle only has open differentials we typically recommend a rear, which will be more effective when off-road hill climbing,” said Sebastian Civitarese.
When should you not use a diff lock?
First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow.
How fast can you drive when the differential lock is engaged on the vehicle? When using the differential lock, your speed should not exceed 25 mph.
Can you turn on diff lock while driving?
What happens if you leave diff lock on?
This can result in the vehicle failing to deliver enough torque to the drive wheels to keep the vehicle moving forward, at which point it will be stuck. The diff lock forces all wheels to spin at the same speed, regardless of traction.
Do you use diff-lock in mud?
As the name suggests, a diff-lock locks the axle so that the two wheels turn at the same speeds. Here’s an example of when this is useful: you’re driving in muddy conditions and one wheel starts to spin in deep mud while the other wheel is on firm ground.
