Check the listing for details. Floyd Rose Heavy Duty Noiseless Tremolo Spring (1 pc) - Red. Condition: New. Listed at 6.40 USD. OPEN BOX ITEM: We typically stock small parts like this in bulk. As such, this item may arrive without retail packaging. This higher tension heavy duty spring is ideal if you're using heavy gauge strings, if you want to use fewer springs in your tremolo cavity, or if you like more resistance from your bridge. Using a revolutionary new polymer to eliminate noise, these German-made springs will silence any sounds resulting from spring tension that might be emanating through your pickups, giving your tremolo-equipped guitar a tighter, crisper sound. Specifications: Length: 62.2mm Note: The same spring as Floyd Rose SKU: FRTSNRDP but offered here individually to reduce waste. Before installing, use a blade to scrape the coating off of both the claw and block ends of the springs to ensure proper metal contact for string grounding. Professional installation is strongly recommended. Improper installation may result in damage to the product and/or instrument.
