Mustang limited slip differential install

Still, the sheer number of Super Duty trucks that left the factory with Trac-Loks means they are inexpensive. Our truck came with a three-pinion differential, while the differential we bought had two pinion gears. We may have installed the two-pinion differential if all we did was drive around an empty truck, but this F never leaves the driveway without being loaded to capacity.

Plus, our manual transmission is more likely to shock load, and break, a spider gear than an automatic would. We put the used center section on the shelf and went back to the drawing board. Time to talk to some experts. This massive company spends most of their time making parts for OEMs in a wide range of industries. Need a differential for your Dodge or an actuator for your Airbus? One of those aftermarket brands is Eaton Performance.

You can buy an Eaton Performnce differential for almost any common rear end, including the full-floating Sterling Eaton Detroit Locker Differential:. Detroit Lockers are the most aggressive automatic differentials in the catalog, and lock both wheels together under power by replacing the spider gears with a pair of ratcheting cogs that are either engaged or disengaged.

That experience is what led us to cross the Detroit Locker off our list immediately: Off-road, nothing compares to a locked differential. But on the street, there are just too many compromises. These are either fully locked or open, with no progressive step in between, so using one on the street means clicking noises, loud bangs, and the occasional chassis disruption during transitions from locked to unlocked. Eaton Posi Differential:.

Eaton Posi is a traditional clutch-type limited slip, similar in design and function to the one Ford offered to install when our truck was on the assembly line. Eaton claims that its modern design and materials mean that a Posi will last the life of your vehicle before wearing out, and these differentials promise much of the off-road ability of a locker with much, much better street manners. This differential is probably the best compromise in the catalog, which is why its basic design is exceedingly common on OEM truck order forms.

Eaton Detroit Truetrac Differential:. Rather than clutches or ratcheting teeth, the Truetrac is a helical limited-slip. During tight turns on pavement, these differentials act exactly like open differentials. But as soon as one wheel starts to spin when accelerating from a stop, the differential locks like a clutch-type limited slip.

Helical limited slips are favored by OEMs in passenger car applications because they have exceptional street manners without any wear items. On the street or in a sandy parking lot, this is a meaningless technicality: Multiply the torque of a tire on wet pavement, and the result is plenty of holding power for the other tire on wet pavement. Choosing a Differential:.

The performance will be excellent as the traction is near perfect. Since the limited slip differential can take power away from a wheel that is losing traction and give more power to other wheels with traction, this helps prevent excessive wear on the tires. Otherwise, the tire with limited traction would simply spin in place and wear at a faster rate. A limited slip differential will not be a terribly costly upgrade to make on your vehicle if one is available.

Once other wheels start to lose traction, the differential will transmit more of the power over to them. As a result, the vehicle could end up being pulled to just one side.

In addition to fixed value LSD, torque sensitive, speed sensitive, and electronically controlled variations of LSD exist. Some will be able to control various elements differently. A differential is designed to let a set of wheels rotate at their own separate speeds. Most vehicles have one differential in the front axle or rear axle, depending on whether it is a front-wheel-drive or rear-wheel-drive vehicle.

However, an all-wheel-drive vehicle would have two separate differentials for the front and rear axles. The main purpose of a differential is to help the vehicle make stable turns. But there are different types of differentials which function in their own unique way. The two most common differentials are open differentials and limited-slip differentials. The former is great for turning on clearer roads while the latter is better for road conditions which will likely cause your wheels to slip.

Combine a well balanced suspension package on your Mustang with a Torsen for incredible traction! The Torsen's unique torque-sensing ability keeps engine power going to the ground during changing traction conditions. The Torsen functions as an open differential as long as the amount of torque transmitted to each rear wheel remains equal. When one tire begins to lose traction, the Torsen instantly senses the change in torque being applied to the ground.

The excess torque that cannot be delivered to the ground by the tire that is beginning to lose traction is delivered to the opposite tire, which has better traction and can take more torque. The Torque Bias Ratio TBR is the ratio indicating how much more torque the Torsen can send to the tire with more available traction, than is used by the tire with less traction. This ratio represents the "locking effect" of the differential.
