THE ORIGINAL. Often imitated, but never correctly. Bare Knuckle Paul started making these chain tensioners almost 10 years ago, to help you set your driveline up and never have to worry about chain stretch and disturbing the relationship between tire and fender. We’ve sold hundreds of these over the years, and our sprung tensioner is still one of our best sellers. The entire assembly is US made. Requires fitment and welding by a qualified professional.
