Steering quickener on the street

[JJSmitches]

Does anyone use a steering quickener similar to this
http://http://www.speedwaymotors.com...qx/product.htm

on their street car? My steering box is only a year or sold old and when it was replaced the shop put in a slower box than what was in it when I purchased the car. When I took it back they tried to explain that they didnt do anything wrong and that the part was correct for the year vehicle I have.

Im thinking since my box is still so new I could purchase one of these quickeners rather than spend more money on a completely new box.

Any comments or suggestions?
