Overview: Since the introduction of the Fin turnbuckle sets designed specifically for style, durability, and performance, a new standard is set. The base of the turnbuckle design is centered on a beefy 5mm square titanium which gradually tapers down into a thread base design which accepts the rod ends featured in the kit. The focus of the styling surrounds the lengthened adjustment area and the “finned” cuts that rotate about the center. The JConcepts 2pc 4x56mm set is compatible with the Tekno NB48.3 and EB48.3 steering assembly. The optional set is handy for racing using an optional steering assembly used by Ryan Maifield on the Tekno NB48 2.1 and EB48 2.1. The Fin turnbuckles are lightweight, and the original design brings out the glamour and quality that makes titanium one of the most sought-after exotic materials in the world. The JConcepts turnbuckles are produced with left and right-hand threads with the left conveniently marked for easy orientation.
