Review on ECCPP Replacement 23Pcs Black Spline by Ken Reed

These jam nuts are made of strong forged steel. I got rid of the standard cheap nuts on my Jeep that had aluminum splines. They are high quality and well made. The only reason I didn't give them five stars is because, like some other buyers, I noticed a little rust on some of the nuts after about a month. At this price I can live with some rust. This is preferable to crumbling a cheap nut.
