JConcepts is Titanium with the introduction of the Fin turnbuckle sets designed specifically for style, durability and performance. The base of the design is centered around a .143” titanium hex size which gradually tapers down into a 3mm thread base design which accepts the standard Yokomo ball-cup configuration. The focus of the styling surrounds the lengthened adjustment hex area and the “finned” cuts that rotate about the center.
The turnbuckles are lightweight, and the original “Fin” 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 being conveniently marked for easy orientation. The #2557-DTMB and #2557-CALB has another feature, a black coloring which gives the stealthiest look in the pits and on the track.
