Whiteline Trailing Arm Upper Bushing Kit

Whiteline's Trailing Arm Upper Bushing Kit line delivers a proven rear suspension upgrade for vehicles equipped with live rear axle configurations. Engineered to correct the excessive movement and deflection caused by worn or deteriorated factory rubber, these bushings restore precise rear axle control, improve brake feel, and tighten overall handling response across all driving conditions.

At the core of every Whiteline bushing is their proprietary Synthetic Elastomer compound—a long-chain polymer formulated for superior tensile strength, elasticity, and shape memory. Unlike conventional OEM rubber, this advanced material resists oil, grease, ozone, and weathering while maintaining consistent hardness under load, eliminating the progressive softening and deflection that degrades factory bushings over time.

Whiteline further refines bushing performance through purposeful engineering details, including internal bore knurling and grease retention features that maximize lubrication at the pivot interface, minimizing noise, vibration, and harshness (NVH) while extending service life. Each bushing is precision-manufactured to strict tolerances to ensure correct suspension geometry and accurate fitment across all supported applications.
