Common questions
What does a primary chain tensioner do for my Sportster?
It automatically adjusts tension on the primary chain during acceleration and deceleration, keeping it properly seated. This reduces clunking during shifts, minimizes wear, and provides a smoother ride.
Will this tensioner eliminate all noise from my transmission?
While the Hayden M6 tensioner significantly reduces clunking on shifts and primary drivetrain noise by maintaining steady chain tension, some mechanical noise is normal in any V-twin primary system.
Is installation of this tensioner a complex process?
Installation generally requires basic hand tools and familiarity with primary drive components. We recommend consulting your Sportster's service manual or a professional mechanic for detailed instructions, and confirming fitment with our Shop by Bike tool.
