These are made of steel, and finished with a nice black oxide finish.
3/8" thick. 0.65 lbs each. A full set will add 1.95 lbs to the rear of your KRG Bravo or X-Ray.
NOTE: The color of the spacers may vary slightly from spacer to spacer and batch to batch. The black oxide process we use to blacken the steel is not exact, and therefore shows a variance in color. We do our best to get each one as black as we can, but if you want a true consistent black we recommend a coat of black spray paint.
