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.
Is limited slip the same as friction modifier?
Friction Modifier in Non-Limited-Slip Differential
All differentials use gears, bearings and shims. Limited-slip differentials have additional clutch packs.
What does limited slip differential additive do?
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.
What happens if you don’t use limited slip additive?
What happens if you don’t 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.
Should I add 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).
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.
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.
Can you add 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..
Does Valvoline gear oil have friction modifier?
Valvoline SynPower 75W-140 is recommended for use where Ford M2C-192A, GM 12346140, Chrysler MS-8985, or GL-5 SAE 75W-140 gear oil is specified. … The addition of a supplemental friction modifier (Ford M2C-118-A, Chrysler MS-5630, or GM 1052358)
is not required
.
Do you need limited slip additive with synthetic oil?
Should I use a friction-modifier additive with AMSOIL synthetic gear lube? AMSOIL synthetic gear lubes
are limited-slip capable and do not typically require an additional friction-modifier additive
. However, depending on the differential’s friction material and degree of clutch wear, chatter can still sometimes occur.
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.
Can I use 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.
Will limited slip additive hurt?
Won
‘t hurt a thing.
How do I know if I have a limited slip differential?
The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential.
If it spins in the same direction
, you have a limited slip differential, or LSD.
