What was the first positive traction car?

Not surprisingly, the big auto producers were the first to get into the Positraction game. In the late 1950s, General Motors implemented their restricted slip differential units (positive traction) in Chevrolet cars under the name “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 was the first car with a limited-slip differential?

Early history

In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to 160 km/h (100 mph).

What's better limited slip or posi?

The limited-slip differential is similar to the positraction differential, but allows the wheel with traction to have only a limited amount of greater power than the wheel that is slipping. ... A limited-slip differential will prevent the tire with less traction from separately spinning.

Do Corvettes have positraction?

A Positraction rear axle, which can be specified with a Corvette ratio, routes engine power to the rear wheel with the greatest traction. This is especially valuable on muddy, slippery or other irregular surfaces, in sand and snow.

Do front wheel drive cars have Positraction?

Front-wheel drive is not positraction by itself; it needs some helpers. It can give your car better traction because you have the weight of the engine over the powered wheels, but there are still those who swear by rear-wheel drive, even when it skids in snow or ice or rain.

Did the Chevy Corvair have Positraction?

No, It Doesn't Have Positraction | Auto Universum.

When did positive traction come out?

In the late 1950s, General Motors implemented their restricted slip differential units (positive traction) in Chevrolet cars under the name “Positraction.” It is the word used to describe the process that allows drivers to have more traction control over their vehicles than they would with an open differential.

Did the 1963 Pontiac Tempest have Positraction?

Pontiac's Tempest had full independent suspension and rear-mounted transmission, and optional (at least by '64) positraction. Here's a long courtroom quote from the the movie "My Cousin Vinny."

What is a Salisbury differential?

The Salisbury diff is sometimes referred to as a 10-bolt because it has 10 bolts holding the crown wheel and there are 10 bolts holding the cover on. However, despite the similar name, there are absolutely no interchangeable parts between these and American GM 10-bolt diffs.

Is a Detroit Locker Streetable?

Can I run a Detroit Locker on the street? While many people do use the Detroit Locker during everyday street use, the Detroit Locker is a very aggressive traction aiding differential, initially developed for off-highway, heavy-duty applications. Eaton also makes many applications for on-highway, heavy-duty trucks.

What is the difference between a Detroit Locker and Truetrac?

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.

Can you do a burnout with a limited slip differential?

So going back to your question yes it is possible to perform a burnout with a limited slip differential and infect it would be a better burnout as both drive wheels would be getting equal amounts of power, it will prevent you spinning up just one single wheel and looking like an amateur.

What is a limited slip differential do?

They work by shifting a portion of the torque to the wheel with the most traction while limiting the slip on the wheel with the least traction. Because of this, limited slip differentials are often referred to as “torque sensing”. Like an open differential, the wheels can rotate at different speeds.

How do I identify my Corvette rear end?

Just jack it up in the rear and turn your tires one full revolution. If your drive shaft turns 3.08 times then you have a 3.08 rear end. If it turns 2.72 times then you have a 2.72 rear end. It's as simple as that.

What is Positrack?

Posi-Track is a shortened generic term for the GM-branded name "Positraction." It is a type of limited slip differential. ... In basic terms, a differential takes the power from the output drive of your engine and transfers it to your wheels.

Is posi traction the same as a locker?

With a locker both wheels will spin at the same speed. With a posi it allows the wheels to turn at differenthe speeds. When turning the inside wheel needs to turn slower than the outside .
