Whiteline Suspension Suspension Trailing Arm Bushing

Why Whiteline Trailing Arm Bushings Stand Apart

The trailing arm is one of the hardest-working links in any rear suspension system. Suspension trailing arm bushings sit at its primary mounting points, absorbing the combined forces of braking, acceleration, and cornering loads — all while keeping the rear axle in precise alignment. Factory rubber bushings degrade, crack, and allow far too much deflection over time. Whiteline Suspension was engineered from the ground up to solve exactly that problem.

Advanced Synthetic Elastomer Technology

Whiteline trailing arm bushings are produced using a proprietary synthetic elastomer — a precision-formulated polyurethane compound that goes far beyond off-the-shelf urethane. Whiteline trailing arm bushings offer superior dynamic alignment precision by controlling excessive movement, providing more predictable handling and driver confidence in every situation. The material itself is engineered to resist oil, grease, ozone, and weathering, making it significantly more durable than the soft rubber found in OEM components.

What separates Whiteline's formulation from generic polyurethane is the attention to NVH (Noise, Vibration, and Harshness). Precisely placed dampening voids reduce harshness from sudden road inputs, while the bushing compound maintains a consistent durometer even under the most demanding conditions — something standard rubber cannot do once it begins to compress and age.

Engineering Details That Make a Difference

Every Whiteline trailing arm bushing kit is designed with several key features that reinforce long-term reliability and performance:

• Internal grease reservoirs provide continual self-lubrication for optimum friction management, reducing wear over the bushing's service life.
• Internal bore knurling and grease retention lips lock lubrication in place, working in tandem with the reservoirs to keep the bushing operating smoothly.
• Protective plating on all metal components acts as a hard barrier that is far tougher than conventional paint, resisting corrosion even in harsh road and track environments.
• Each kit is supplied with extreme-pressure molybdenum disulphide (LM) based grease specifically chosen for extended bushing life.
• Detailed installation guides are included with every kit, making proper fitment accessible for experienced home mechanics and professional shops alike.

Fitment Range: Subaru, Mitsubishi, Toyota, Nissan & More

Whiteline offers trailing arm bushing kits across a wide range of popular performance and sport compact platforms, including Subaru WRX, STI, BRZ, Forester, Legacy, and Impreza, as well as the Mitsubishi Lancer Evolution series, Toyota and Lexus models, Infiniti and Nissan, Mazda, and Audi/Volkswagen platforms. This breadth of fitment reflects Whiteline's deep engineering commitment to each chassis — these are not universal bushings shoehorned into place, but application-specific kits designed to restore and enhance the geometry Whiteline's engineers studied for each vehicle.

Backed by a Lifetime Warranty

Whiteline bushing kits (part numbers W00001 through WZZZZZ) are covered under Whiteline's limited lifetime warranty, reflecting the brand's confidence in its material quality and manufacturing precision. When you install a set of Whiteline trailing arm bushings, you are investing in components built to outlast the vehicle's original rubber hardware — and to improve its handling in the process.
