Are friction modifiers made to help the lsd clutches to lock up or to make them slip more? Just wondering :)

Yes

To slip just a bit easier so that everyday driving, turning, etc doesn't wear them down so fast, and it'll be able to do its job when the time comes.

|  Friction Modifiers - AMSOIL Slip-Lock Additive
IP: Logged
Message:
Thanks shatto,
True: AMSOIL Synthetic Gear Lubes DO NOT require the use of an additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.
Additives? -- AMSOIL Slip-Lock Differential Additive
Effectively Eliminates Gear Housing Chatter
When making a turn, the outer wheels of a vehicle must travel faster than the inner wheels. It is up to the differential to act as a balance arm, establishing constant equilibrium of torques and forces between the left-hand and right-hand driven wheels. In standard (or open) differentials, power is directed to the wheel offering the least resistance. This works well when making a turn, but in a situation where one wheel is lifted off the ground, it causes the suspended wheel to turn while the other remains motionless.
Limited-slip (or positraction) and locking differentials are traction-increasing devices. Locking differentials transfer all available torque to both wheels. The teeth of the spider assembly engage with those on the locker clutch, causing both axle shafts to operate as one. Locking differentials don't allow one drive wheel to spin while the other remains stationary. Instead, they keep both wheels in drive mode, but unlock to permit different wheel speeds when turning. The engaging and disengaging of the teeth on automatic locking differentials often causes a banging and clunking sound. Manual locking differentials usually use an electric motor or vacuum diaphragm to engage the locker, reducing this noise.
Limited-slip differentials allow different wheel speeds when turning, but when one wheel loses traction, greater torque is transferred to the wheel offering more resistance. Limited-slip differentials make use of friction between clutch plates, as opposed to the meshing teeth employed by locking differentials. Transferring less torque per side, limited-slip differentials are generally smoother and quieter than locking differentials, but still sometimes "chatter" when transferring torque to the wheel with traction.
In some differential applications, a friction modifier additive is necessary to reduce chatter. AMSOIL Slip-Lock Differential Additive is formulated with advanced friction modifiers and is designed to eliminate gear-housing chatter in cars, trucks and SUVs equipped with limited-slip, positraction and locking differentials. It also reduces the banging and clunking associated with automatic locking differentials.
AMSOIL Slip-Lock Differential Additive is formulated for use with both synthetic and petroleum gear lubricants and safely replaces manufacturer recommended friction modifiers. Its convenient flip-top dispenser provides quick and easy application to the gear housing. One four-ounce bottle of Slip-Lock treats differential capacities of two to four quarts. It is not for use in automatic transmissions or other applications requiring ATF.
Repeat: AMSOIL Synthetic Gear Lubes DO NOT require the use of this additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.

FYI - Gear Lube Information:
High quality gear oils must lubricate, cool and protect geared systems. They must also carry damaging wear debris away from contact zones and muffle the sound of gear operation. Commonly used in differential gears and standard transmission applications in commercial and passenger vehicles, as well as a variety of industrial machinery, gear oils must offer extreme temperature and pressure protection in order to prevent wear, pitting, spalling, scoring, scuffing and other types of damage that result in equipment failure and downtime. Protection against oxidation, thermal degradation, rust, copper corrosion and foaming is also important.
AMSOIL Gear Lubes delivers unbeatable protection and fuel economy (independent testing shows class 8 vehicles with AMSOIL Series 2000 Synthetic 75W-90 Gear Lube in the differentials obtained up to 4.83 percent more mpg than vehicles equipped with another popular gear lube).
Amsoil Synthetic Gear Lubes have the film strength required to deliver all the protection heavy-duty and high-stress applications need in a fuel-saving viscosity grade. AMSOIL Gear Lubes are recommended for use in all passenger vehicles, commercial trucks and race vehicles.
AMSOIL Gear Lubes exceed the lubrication and performance requirements for gear boxes where API MT-1, GL-4 or GL-5 lubricants are specified.
__________________________________________________
Helpful Differential Recommendations:
-Flush (drain) as much of the old fluid out.
-Differential fluid capacity depends on ring gear and axle housing size.
-Do not over/under fill differential. This could mean a capacity difference of a quart or more and may cause overheating problems. (See the owner’s manual for proper fill level)
AMSOIL gear oils are formulated with friction modifiers for limited slip differential applications. There is no need to add limited slip or additional additives.
-After changing the differential fluid, drive the vehicle in 7 or 8 figure eight turns, so the new lubricant can work its way into the axle assembly.
Synthetics provide the long-lasting protection, fuel efficiency and dependability needed for top performance, even extreme-pressure conditions. Stays fluid in cold temperatures for easy cold-weather shifting.

Yeah. I'm running the Amsoil Severe Gear stuff and it chattered right away :(
I bought some anti slip additive from Checker but it didn't fix it.
Any way to get a sample of that Amsoil additive?? :)
