Advantages of a Limited-Slip Differential • Can possibly be weaker (physically) than a locking differential, depending on the design If you’re an avid autocrosser/road racer, you might want either the limited slip posi to provide the best traction for both straight line and cornering. When making a turn, one tire has to turn sharper than the other on the same axle to complete the turn. Eaton Posi Limited Slip The Eaton Posi is an ideal way to gain traction in trucks that see mild, off-road use or need added traction due to performance enhancements. Some of you people seem to be thinking about lockers, which are a very different animal. This is why a limited-slip or locking differential is much preferred over a spool in a street-legal application. Also. Limited slip differentials give you better traction than locked differentials. The differential compensates for the differences in the tire angle during the turn. This is a gear-driven limited slip that has been gaining in popularity. • Enhances traction in all weather and road conditions, including ice and snow Differential Carrier Components First you have the… Carrier The carrier houses the spider-gears , side gears, and holds the ring gear. even what most call a locker arent ,ie gov-lock.really just a clutch type posi.if it has a friction clutch beside a spidergear ,its a posi/limited slip.truetrac also a posi/limited slip.has gears that work together to preload the side gears .but its NOT a locker.detroit locker is a mechanical locker.lockers the (side … Gear-Type Limited Slip Differential. Positraction and limited-slip are both types of automotive differentials. In recent years, a third type of limited slip differential has been introduced. And this is an excellent question. Limited Slip = Posi Traction. You might think so if you buy into the literature put out by some OE vehicle manufacturers. A locker in the rear, whether automatic or selectable, will give you three drive wheels which can get you out of most situations.

Jun 11, 2009 #1 I am Still working on getting my car together. posi- trac are used on drag strips both wheels are turning at the same time that is why you see them do wheelies at the drag races. Banned. If there were no differe… posi /limited slip are the same thing ,ford called it one thing and gm called it something else. Hey everyone just was wondering what your guys take on putting either a posi or limited slip into my front dana 44 in my 79 ford f150. • Bolt-in applications with zero axle, ring-and-pinion, or axleshaft modification Front axles don't have limited slip. But which one (limited-slip or locker) is better for you? A 4x4 with open diffs is little different than a 4x2 with a locker. While Posi acts as the defender of wheel slip to earlier starts. The. In this video we compare an Open Differential (Ford Ranger) to a Yukon DuraGrip limited slip differential (Chevy Silverado). • Wears tires out more quickly Advantages of a Locking Differential Locker = Axles are locked together and … Auburn limited slip or Auburn locker? Traction control augments the limited slip rear axle at higher speeds. • No servicing But what is the difference? You can hear the clunk of locking & unlocking around turns. Having a traction-aiding diff instead of an open diff not only helps in the dirt, but on pavement as well. Now that we've sucked you in with that title, we'll tell you right now that it's not a matter of which differential is better, it's a matter of which one is better for you! This is beneficial in hard-corner turning. Locking Differential. With a posi or limited slip the power goes to the wheel with the most traction when you are racing. I would suggest a true locker vs posi or limited slip as they are just that; limited. They do make an electric locker for the OP's GM car 12 bolt. If it's more of a toy, then it gets a locker. A Locker locks both wheels under hard acceleration and then unlocks them around turns. • Certain limited-slips can sometimes pull side to side in a front axle application, By clicking Sign Up, you agree to the  Terms of Use. This open differential allows the wheels to spin at different speeds to help in cornering, but will allow excessive wheel spin when one wheel loses traction. A limited-slip differential will prevent the tire with less traction from separately spinning. • True two-wheel drive per axle And of course, a spool can be installed in place of all of them. It's about this time that you're probably asking yourself, "Why wouldn't I completely lock both axles together full time with a spool or something?" Qty: Description Vehicle Applications Toyota 8" Truetrac Performance Differential. Without having a limited-slip or locking differential in an axle, you can lose forward motion when one wheel breaks traction and spins, leaving the other one (wheel) to sit idle. Price: $ 508.96. Limited slips and lockers can be interchanged. Positraction is beneficial when road conditions are wet or muddy. A locker locks both sides all the time (or at the touch of a switch). • Can make snow/ice driving more difficult. Differentials are located in the center of the front axle, center of the rear axle or, in some cases, both. Each does the same, but made for diff useage. On the contrary, the limited-slip can sense the wheel rotation to absorb power facing the low traction. Let’s discuss the. Generally, we tend to let the vehicle's intended use be the dividing line between a locker and a limited-slip-if it's more of a daily driver it gets a limited-slip. 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. Same exact thing. Depending on the manufacturer, there are a lot of different trade names: Posi trac, sure grip or track loc but they all work the same. Auburn cone style limited slips are not rebuildable, and they do wear out. 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. Rear end is stock original with 104 k on it I plan on going with a TA rear cover and 30 spline Moser Axles. Eaton produces an automatically-locking differential called a Detroit Locker that does an excellent job of enhancing traction, and it fully locks when power is applied-something that gives true all-wheel drive, but it isn't always welcomed by a driver in a turn or in icy road conditions. Limited-slip differentials and locking differentials are both added to axles in an effort to achieve more traction in environments where one wheel can break traction and spin, leaving a vehicle with an open differential doing what's known as a peg-leg dance. When a limited slip diff senses that a wheel is spinning, it will automatically transmit more power to the wheel that has more traction. It also allows one wheel to turn at a different speed around turns. 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. This allows the tire to maintain power through the turn. Limited Slip Differential: Pros. • Tires won't "chirp" On top of that, many limited-slip differentials use clutch packs that can eventually wear out. Are on the inside of the carrier you have one on each side. With over two decades of extensive office experience she offers excellent communication and organizational skills. • Extremely durable Your information will be collected and used in accordance with our  Privacy Policy.

The helical worm gears keep torque flowing to the wheel with the most traction, should your 4x4 get into a sloppy mudhole. Eaton also produces a helical gear limited-slip differential called the Truetrac. This is beneficial in hard-corner turning. A spool is fine for something like a drag car that does all of its forward motion in a straight line, but most vehicles need to turn left and right. Though these limited-slip diffs generally have better street characteristics than locking differentials, they do not completely lock both axles together, which can leave one wheel spinning and one wheel caught up if the situation is bad enough. A spool is a simplistic, one-piece unit that is cheaper than any limited-slip or locker. The full-locking capability is integral in extreme driving situations though, and automatically turns the Detroit Locker differential into a spool when engaged. Detroit Truetrac vs. Eaton posi. • Silent operation (unless servicing is required), Cons of a Limited-Slip Differential • Doesn't fully lock both axles together Theres quite a few forms of lockers.

If you’re a drag racer looking for the best traction for the strip, you might want to consider the Detroit Locker as it will handle just about all the power you throw at it. References. A limited-slip differential is one that limits the slip between the axleshafts (or wheels) when power is applied to the differential. More than one of them calls out a limited-slip-device as a locker in the rear axle of the vehicle they’re selling. A locking diff means just that, the wheels are locked together and turn the same even during turns causing a little chirp or slip on the inside tire. In the early 1970s, real muscle cars were fading away, and average Americans were becoming more concerned with a plush ride than with high performance. Equa-loc vs. Trac-loc vs. detroit locker. Side Gears. TC.

All automobiles on the road contain devices between the wheels called differentials, or gear trains. Limited slip works better in a number of situations, there is a thread around here somewhere. Both limited-slip and locking differentials solve a problem with the standard open differential found on most passenger cars. A Limited-Slip Differential generates more traction than the open differential. Limited slip and Posi are the same and work great in rain,snow and ice, the downside is that most have plates that will wear out in time making them less useful. These differentials will not divert 100% of the power to one wheel though. hope this helps. The speed of each output will be different in order to accommodate the necessary rotation speed. I have heard Lockers are noisy and they are. Post Cancel. so it depends on the Brake Lock Diff feature of traction control to reduce wheel spin. Umm...not an expert, but i think this is how each works... A posi will send power to the tire with the most traction, getting you unstuck in a mildly stuck situation. Limited Slips: Gov-Lock Vs.

Generally, we tend to let the vehicle's intended use be the dividing line between a locker and a limited-slip-if it's more of a daily driver it gets a limited-slip. And the difference of these devices. • No accelerated tire wear Power to the other wheel continues until equal control is returned to both tires. Most Limited-Slips, sometimes called posi’s or positraction diffs, use clutches to drive both tires, but allow the clutches to slip when the vehicle corners and the axles need to turn at different speeds. 4x4 Action compare the differences between having an Air Locker, LSD and Traction Control under various real life situations Without some type of axle differential that allows wheel speed differentiation, the vehicle will be pushed straight forward and the inside driven tire will chirp as it skips along. A limited-slip differential will prevent the tire with less traction from separately spinning. Are a very different animal heard about this Truetrac Massage Therapist with TA!
