What is Positraction additive?
What is Positraction good for? Positraction units prevent loss of traction by sending power to both driven wheels. At the same time, each wheel rotates independently when necessary, preventing the non-slipping wheel from losing power. A slipping wheel loses power with the conventional rear end design.
What happens if you dont use limited slip additive? Friction modifier makes the fluid “slicker” so without the additive the limited slip clutches will grab and it will shudder going around tight turns. And yes, eventually it will destroy the clutches and render the limited slip useless.
Do I need limited slip additive? Limited-Slip Differentials
The MOPAR Limited Slip Additive should be added to the gear lubricant whenever a fluid change is made to an axle equipped with a Limited Slip Differential. 2500/3500 Model axles DO NOT REQUIRE any limited slip oil additive (friction modifiers).

What is Positraction additive? – Related Questions
Is 75W90 better than 80W90?
75W90 is synthetic and mostly superior to 80W90, but it costs more. 75W90 has better low temperature viscosity and it is fine to run it throughout. If you’re in a place that does not get very cold, there will be little advantage running 75W90 and in theory, 80W90 may even be more shear stable.
Can you add too much limited slip additive?
If you add too much limited slip additive, you’ll notice your wheels will break loose super easy and you’ll get wheel-spin just making turns from a stop. If you make that mistake (like I did), just drain the oil and refill and you’ll be good.
What is better posi or limited slip?
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.
Is limited slip better than open?
With an open/ standard differential, gears called spider gears allow the wheels to vary speeds to negotiate turns without binding up. When a limited slip diff senses that a wheel is spinning, it will automatically transmit more power to the wheel that has more traction.
Which is better limited slip or locking differential?
Limited slip differentials provide your vehicle with the best traction around. Locking differentials might give you good traction too, but the traction that you will experience with limited slip differentials is better. For starters, they will make it easier to turn on roads which are slippery and wet.
Is it bad to put limited slip oil in open differential?
Registered. our limited slip differentials require adding a friction modifier to the oil. it will work fine in an open differential. and, not likely what you’re looking at actually has the modifier in it.
What happens if you dont use friction modifier?
The friction modifier increases the friction between the clutch plates. If you run a gear oil that has no friction modifier in it the diff will act more like an open differential. In short it will decrease the function of the lsd. It won’t cause any damage.
Does Lucas gear oil have limited slip additive?
They contain a special additive package that increases lubricity and insures less gear noise and longer bearing life. Designed to stand up to high temperatures without losing its lubricity. Excellent for use in limited slip differentials.
What oil goes in a limited slip differential?
Synthetic 75W-90 Limited Slip Gear Oil utilizes the same synthetic oil technology as Driven’s 75W-140 Limited Slip Gear Oil to provide consistent limited slip differential performance.
Will limited slip additive hurt my car?
Limited-slip differentials have additional clutch packs. Since there is nothing in any differential that is not in a limited-slip differential, there should be no harm in using a friction modifier in a non-limited-slip differential, although there is no need for it.
Is posi traction the same as limited slip?
TOM: Actually, Jeannie, “posi-traction” is just Chevrolet’s name for limited slip differential on passenger cars. RAY: On Chevy trucks, limited slip is called “locking differential.” That’s just a heavier duty version of “posi-traction,” and it operates ONLY on the rear wheels, even if you have four-wheel-drive.
What’s thicker 75W90 or 75W140?
So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.
Is Thicker gear oil better?
Higher viscosity provides a thicker film, higher wear resistance, and less deformation of the gears as time goes on. Low viscosity oils, on the other hand, are best for high speed systems with lower load. They provide a thinner film and better cooling to match the higher speed of the gearbox in question.
Can I use 80W 90 instead of 75W90?
Ans: Yes, you can mix 75w90 with 80w90.
How much limited slip additive do I add?
The recommended mixing ratio is one fluid ounce of Limited-Slip Axle Additive Concentrate to one pint of API GL-5 gear lubricant.
What does limited slip friction modifier do?
What Exactly Does Friction Modifier do? Limited-slip differentials contain clutches that automatically deliver more power to to a wheel that has traction and less to a wheel that is slipping. Friction Modifier additive eliminates noise that can occur when limited-slip mechanisms engage and disengage.
Can you have too much friction modifier?
Re: is it possible to add too much friction modifier? Add a bottle. The idea behind the friction modifier is to make the clutches slip easier.. The fiber discs will only absorb so much of the modifier, so you can’t really put to much in..
Are 3.73 or 4.10 gears better?
4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.
Is G80 a locker or limited slip?
“G80” is a GM order code for the limited slip diff; originally named “Positraction” by GM. . It’s been the same order code for 40 years or more.
Can you put a locker in a limited slip differential?
Because gear-driven limited slips only bias torque when needed, they do no create any binding like a clutch-type LSD or a locker possibly could, so they can be used in front ends with no negative impact.
Are front differentials limited-slip?
Gear-type limited slips can edge higher and stay more mannerly because they are typically not preloaded. If an aftermarket limited-slip is built for front axle use, it’s usually no more than around 2:1. The reason we have a differential in the axle is to allow turns without tire scuffing.
