B74.2, 3.5mm Fin Titanium Turnbuckle Set (Burnt Blue)

JConcepts Titanium Fin Turnbuckle Set in Burnt Blue for the B74.2 RC car is a high-performance upgrade that combines durability, style, and precise adjustability. Built around a .143” (3.7 mm) titanium hex base that tapers to a 3.5 mm thread base, it’s designed to work with standard ball cups used on a wide range of RC setups. The distinctive fin-inspired geometry keeps the assembly lightweight while maintaining strength, and the burnt blue finish delivers a bold, premium look on the chassis.

Left- and right-hand threads with the left-hand side clearly marked for easy orientation, plus a lengthened adjustment hex area and the signature “fin” cuts that rotate around the center, define the design. Made from machined titanium, these turnbuckles are lightweight yet robust, offering smooth, precise toe and camber tuning for race-day setups. The burnt blue finish features color variation across the blue spectrum for a distinctive appearance, and a turnbuckle adjustment wrench is sold separately to simplify adjustments.
