torsion keys

Anyone has changed his torsion keys to this one and is it worth it http://www.autoaccessory4u.com/99chsi154wdt.html (http://www.autoaccessory4u.com/99chsi154wdt.html)

I tried to adjust my original torsion keys to get it lift a little but the ride become real stiff and the car pulled to the right.

Any suggestions

I have heard the Ford torison keys work too, and only costs $40

Any idea which year and model?

I am not sure.. I read about in the Forums here. Do a search on Ford Torision Keys.

Thanks I found it :)
