The XRAY 303722-O Aluminium Rear Lower 1-piece Suspension Holder is intended for the rear bulkhead of XRAY T4 models and focuses on improving traction on asphalt. Its design aims to make rear handling more predictable on low-to-medium grip layouts.
This component pairs with the right aluminium holder #303716-O and left aluminium holder #303717-O. It is useful for competitors refining rear geometry and looking for a consistent setup across laps.
Made from Swiss 7075 T6 aluminium and finished by CNC machining, the holder delivers a strong but lightweight option for the rear suspension. The machining ensures tight tolerances for repeatable performance.
