The Texas Power Bars have proudly been manufactured in the USA since 1980. Before shipping to their production facility, the shafts are centerless ground, demagnetized, and oiled to guarantee optimal quality. The shafts are then machined and knurled to provide superior grip, a quality still unsurpassed in the industry. A variety of finishes are available, including black zinc and chrome plating. Moreover, the sleeves can be procured in either raw or chrome plated options.
