Collection: primary chain tensioners

The primary chain is the drive component that connects the engine to the clutch and transmission – and as the miles wear on, it stretches over time. A loose primary chain is noisy, causes wear, and reduces the efficiency of the drive. The primary chain tensioner keeps the chain at the correct tension to ensure the drive remains quiet, clean, and reliable. In this category, you will find primary chain tensioners and their related components for Harley-Davidson, Indian, and metric custom motorcycles. Some are manual, screw-adjustable, while others are automatic, self-adjusting types that continuously handle chain stretch on their own – meaning less maintenance and smoother operation. The selection includes OEM replacement series and performance-oriented parts, from established brands, in qualities trusted by riders. The right tensioner protects not only the chain but also the life of the clutch and transmission. Check your machine's exact model, year, and primary drive type to ensure you choose the compatible part – a quiet, smooth drive will take care of the rest.
