The Synergy Double Adjuster Tube Adapter is designed to eliminate the need for jam nuts that are normally used when building link suspension & steering systems. The use of the Double Adjuster allows the suspension/steering link to be adjusted without removal. The Double Adjuster allows the user to fine-tune the suspension/steering geometry by loosening the pinch bolt and turning the adjuster sleeve. The tube adapter seals the link off from water or other debris entering the link which can cause damage over time.An integrated drain hole lets any water that enters the threads of the adapter drain out.
