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 does Ford friction modifier do?

Friction modifiers are mild anti-wear additives used to minimize light surface contact, such as sliding and rolling. Friction modifiers are deployed to prevent wear on metal surfaces. Mostly used in transmission fluids and engine oils, these additives help slow down wear and increase fuel economy.

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 happens if you don’t add 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.

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 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.

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.

What is the best friction modifier?

1. Editor’s Pick: Lucas Heavy Duty Oil Stabilizer.
2. Marvel Mystery Oil.
3. Hot Shot’s Secret Original Stiction Eliminator.
4. Archoil Oil Additive (AR9100)
5. Prolong Super Lubricants Engine Treatment (PSL11000)
6. REV X High Performance Oil Additive.
7. Liqui Moly Cera Tec Friction Modifier.
8. Restore Engine Restorer & Lubricant.

What is limited slip differential additive?

Kendall® Limited-Slip Axle Additive Concentrate is a special additive used to modify the frictional characteristics of axle lubricants for use in limited-slip differentials. It helps to eliminate chatter in limited-slip differentials when added to non-limited-slip API GL-5 gear lubricants.

Can you use limited-slip oil in a non limited-slip diff?

All differentials use gears, bearings and shims. 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 limited slip and posi traction the same thing?

Despite the fact that a lot of folks confuse the terms “posi” or “Positraction” with “limited slip,” the fact is that the two are basically one and the same. Today, all positive traction systems are referred to as limited slip systems.

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.

Do you need oil additive for truetrac Posi?

Unlike a traditional clutch-type posi, a Truetrac requires no special oil additive or maintenance. With silky-smooth positive operation and no components to wear out, the Truetrac maintains day-one performance for the life of the unit.

Can a Posi clutch be used on a trac loc?

No it shouldnt chatter if its used. However, it is possible that the posi clutches are worn, I’d play it by ear, put a bottle in and some good gear oil and see what it does. I wouldnt bother with two if the posi is used, that would be overkill.

What kind of lubricant do you use for Posi?

Too much additive makes the posi less effective. Myself and BigGearHead both have Amsoil available for you, through ordering direct from Amsoil if you want. In my 69 10 Bolts, I used GM oil (80W90, P/N 89021671) with one 4oz bottle of GM Limitted Slip Axle Lubricant Additive (P/N 1052358).

Is the Trans-X Posi trac limited slip gear international?

Trans-X Posi-Trac limited slip gear oil additive is designed to quiet chattering differentials and improve gear oil performance. Domestic Shipping: Item can be shipped within U.S. International Shipping: This item is not eligible for international shipping.
