phantom grip locker

Post by suzimad »

has anyone got one in their zook.

i did a search and came up with a few threads from daihatsu guys.

i use one in the car i race , interested in putting one in my sierra , no clunkiness of a lockrite , no leaking seals/ broken hoses of an airlocker and a 1/4 of the price, just accelerate and it locks up.

thoughts ?

its an lsd that locks harder on accel , yet still retains drivability on cornering etc.

but arn't lsd's usless when you lift a wheel up because they need friction to work?

they lock the sun gears on acceleration , not sure of the friction you refer to at the wheels

Aren't these a "conversion" for a regular diff? I would have thought these would make the original diff have a short life as they rely on some amount of friction on the side gears etc that were never intended to have friction applied to them. To me it looks like they kind of ramp load, so they get tighter as more torque is fed in. Ideal for a road car that typically has fairly even wheel loading from right to left under power, but less suitable for an off road car.

Part of the problem with "accelerate and it locks up" is that it doesn't work if your trying to idle though something or take it very easy.

They are the absolute last resort IMO....

To make them work even partly effectively they apply significant axial loading to the side gears via hardened steel blocks.

These gears were never designed to take this sort of load and are relatively small in the scheme of things. If you have a windowed diff then the axial load can contribute to breakages. They also polish very quickly thus reducing their effectiveness. Hardened steel rubbing on hardened steel doesn't work well as friction surfaces.

The experimenter in the Hatsu section did some trial work and I havn't heard anything since - so draw your own conclusions.

Perhaps fractionally better than an open diff but its a VERY small fraction.
( usual disclaimers )

It seemed like a much better idea when I started it than it does now.
