The Flyer arm is the same 3/16" thick arm as the standard arm but without the metal screw on tip. This arm has just a rounded off end but you can slip on any plastic Fender tip. This should not be confused with the thickness of the Heavy Metal 8539 arm. This arm is 3/16" thick and the 8539 arm is 1/4" thick. Right hand only.
Fits new and old Pro, Hybrid, Flyer, X-Trem and "Gibson" stamped Kahler bridges and all USA Stratocasters. This does not fit the fulcrum models such as the 2720 Spyder, 2710 Killer, 2760 Steeler or 2500/2520 Traditional. Although the picture is similar, the fulcrum arm is part 8530. Does not fit bass tremolos. Bass tremolos also use arm 8530.
These are the original 303 stainless steel arms that came stock on all FLYER guitar tremolos during the 1980's. These can also be re-bent in a vise to your desired angle.
