What diff is best for drag racing?

What type of differential is used for drag racing?

Other Spools (1)

Open Differentials are the most basic type of differential. An open differential is designed to free-up the tire with the least traction. This is accomplished with a set of spider gears which allow the free wheel to spin faster so it can catch the wheel with the most traction.

What kind of differential is best for racing?

Limited slip differential

As we saw, both a spool and an open diff have their issues, especially in racing conditions. Most race cars thus use a limited slip differential, which offers the best of both worlds. You can tune the differential to behave as an open differential in certain conditions.

Is limited slip differential good for drag racing?

Because this is a limited slip differential, it will allow one wheel to slip while the other grips, meaning that when cornering you won’t have full lock on both wheels. This helps prolong tire life, but it is still a great differential for drag racing where traction is of utmost importance.

What type of rear end is best for drag racing?

Ford 9″- The Ford 9″ is definitely the most popular of the rear ends in drag racing. It offers good strength characteristics and the largest variety of gear choices. The thirdmember type center section allows a racer to have multiple gear ratios available and is much easier to change than a rear loading type rear end.

Do drag cars have locked diffs?

So what’s a drag racer to do? Install a locking differential. These are known as lockers, locking diffs, spoolers, or spooling differentials. This is an example of a newer-style Eaton Posi-Trac diff carrier.

Can you use a spool on the street?

Spools were developed for racing and racing only. They are designed for straight line acceleration and they have no practical use on the street. Spools are dangerous on wet roads and are hard on axles and tires. Use one at your own risk.

What differential is best for drifting?

For drifting or rally driving, occasionally a two-way LSD may be the best option, as it’s more desirable in these scenarios for wheel speeds to remain relatively equal.

Is limited slip differential worth it?

And limited-slip differentials aren’t just useful on the road: race cars and off-roaders use them, too. However, they do cost more than open differentials and require more maintenance. It’s worth pointing out, though, that differential fluid doesn’t really last the lifetime of the car.

Can you drift with a Torsen differential?

It’ll be fine. The problem with torsen is yay they don’t actually lock up so your transitions and throttle input won’t be as precise. It’ll be like driving a car with a semi worn lsd.

Can you lock a limited slip differential?

Limited-slip differentials are considered a compromise between a standard differential and a locking differential because they operate more smoothly, and they do direct some extra torque to the wheel with the most traction compared to a standard differential, but they are not capable of 100% lockup.

Is limited slip as good as a locker?

The benefits of the limited slip versus the locker is that it’s “on” all the time, and that can even help on the street. The selectable locker is nice because it absolutely locks both tires (both sides of the axle) together when engaged, and allows completely normal operation on the street when disengaged.

Is limited slip the same as PosiTraction?

There is no difference. They do the same thing, work the same way, and have the same effect. They are 2 different brand names for the identical same parts, down to the very part number in some instances. “PosiTraction” was simply GM’s trademark for their limited slip rear ends in the 60s.

How much horsepower can a 12 bolt rear end hold?

Chances are your truck has a 12-bolt rearend, but if not, it’s fairly easy to get your hands on one. Not only are they common, but they can also be pretty solid when built correctly. In fact, they can stand up to around 800 hp, which is perfect for a street truck with some performance mods under the hood.
