Whiteline’s heavy-duty upper trailing arms wear a protective black powder coat that resists corrosion better than conventional paint. The adjustable design provides a window to optimize pinion angle, helping minimize vibration and improve rear-wheel power delivery. Engineered with the installer in mind to reduce the need for specialized tools. Whiteline suspension bushings are formulated to resist oil, grease, ozone, and weathering, delivering reliable response in demanding conditions.
