What a neat option for a less than stellar manufacturer device. Price point is awesome, great looking addition to "hot rod up" the look of my cars rear axle. Professional grade, well worth the money.

This was exactly what I was looking for to move my axle vent a little higher in the chassis on my mud drag truck. Cheap, but high quality. Worked perfectly for less than I expected to pay.
