This curved arm is exclusively tailored for Rolls-Royce WRAITH, GHOST RR4 (2011–2018), and DAWN models, strictly matching OE numbers 31126775959 and 31126775960 to align with the brand’s ultra-luxury automotive engineering standards.
Crafted from high-rigidity forged aluminum alloy, it balances exceptional structural strength and lightweight performance: it reliably supports the heavy chassis load of these luxury models (exceeding 2.4 tons) while minimizing unsprung mass, which reduces suspension response lag and enhances the harmony between the vehicles’ iconic smooth ride comfort and precise handling agility—hallmarks of the Ghost series.
As the core structural component of the front suspension boom system, it undertakes dual critical roles: establishing a stable mechanical link between the wheels and vehicle frame to ensure precise transmission of driving, braking, and steering forces; meanwhile, its integrated angle adjustment function maintains accurate wheel positioning paramete…
