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 4mm titanium hex size which gradually tapers down into a 2.5mm thread base design which accepts the standard Losi Mini-T and Mini-B ball-cup configuration. The focus of the styling surrounds the lengthened adjustment hex area and the "finned" cut 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 for ease of adjustment. The #2975 has another feature, a black coloring which gives the stealthiest look in the pits and on the track.
