DRAG SPECIALTIES Primary Chain Adjustment Kit (ref. G15-0940K)
Replace the automatic tensioner with a reliable manual tensioner to regain control over the adjustment of your primary transmission. Designed for Vintage/Classic and Touring bikes, this Primary Chain Adjuster Kit in black finish allows you to adjust the chain tension according to factory specifications (from 5/8" to 7/8"), thus avoiding problematic over-tightening that can occur with some original automatic tensioners.
Ideal for Harley-Davidson owners seeking a more direct adjustment of their primary — particularly FXDLS, FLSTFBS, and FLSS models (2017, 1800 cc) — this kit fits neatly without major modifications. Present your primary, adjust precisely, and continue your journey with complete mechanical peace of mind.
