DRAG SPECIALTIES – Primary Chain Adjustment Kit (ref. G15-0940K-N)
This manual tensioner kit for primary chain is aimed at riders who want a precise and controlled adjustment of the primary transmission. Designed to replace or complement the original automatic tensioner, it prevents excessive tightening of the chain that can occur with automatic systems, while reducing the load on the crankshaft and transmission bearings.
Ideal for Vintage/Classic and Touring, this kit provides robustness and adjustment precision without unverified technical promises. Particularly suitable for Harley-Davidson FXDLS, FLSTFBS, and FLSS (2017 1800 cc models) listed in compatibility.
