Shout out to those folks. To start with Love their products. Went a little crazy and ended up with K-9 Extremes, Beaver Extremes and 1.5 double jaw Extremes. Now to the shout out. I had a thread recently about some K-9 Extremes I picked up to add to the ones I purchased from NO B S. They had been neglected and in the tear down phase I found some parts that needed replaced. Called NO B S and for a reasonable price got them right out to me. During re assembly discovered that the main springs were shot. Another call a more than reasonable price and They arrived yesterday. Hard to beat great customer service. Thanks and tight chains to Kendall and the crew at NO B S.
