XRAY XB4 2024 Fin Titanium Turnbuckle Set Stealth Black (JCO2724-2)

XRAY XB4 2024 Fin Titanium Turnbuckle Set in stealth black is a six-piece, high-grade titanium kit designed to fine-tune the XRAY XB4's suspension geometry. Built around a 3.7mm titanium hex interface that tapers to a 3.5mm thread base to fit XRAY ball cups, it uses left- and right-hand threads with the left-hand side clearly marked for quick orientation. The Fin styling reflects the original JConcepts design, delivering lightweight strength and a premium look while enabling precise, repeatable adjustments for competitive racing.

Crafted from durable titanium, these turnbuckles are lightweight yet strong for on-track performance. The longer adjustment hex area and the distinctive Fin cuts center the adjusting point, while the 3.5mm thread base matches XRAY ball cups. Older XRAY models may require a small resizing of the ball-cup bore (2.8–3.0mm drill) to accommodate the 3.5mm threads. With left and right threads and clearly marked orientation, setup is straightforward and repeatable, making this set a popular choice for serious racers.
