Whiteline Control Arm (Upper & Lower Bushing)

1973–1977 Buick Century

Part #: W56430

Overview

If you're experiencing uneven tyre wear, unbalanced braking, or a less predictable rear end during cornering on your Buick Century from 1973 to 1977, worn or degraded control arm bushings could be the culprit. Over time, factory bushings can deteriorate due to age, exposure to elements, and driving conditions, leading to compromised handling, increased noise, and reduced safety. Replacing these worn bushings with high-quality aftermarket options is essential to restoring your vehicle's optimal performance and ride quality.

Whiteline's control arm bushings are designed specifically for enthusiasts who demand durability, precise handling, and a safer driving experience. Whether you're restoring a classic or improving your daily driver, these bushings help support better suspension response, reduce unwanted movement, and enhance overall stability.

Construction & Design

Whiteline control arm bushings are constructed with a focus on durability and precise fitment. The bushings utilize a one-piece synthetic elastomer core, molded into a robust housing that maintains shape under load. The design incorporates advanced materials that resist cracking, hardening, and deterioration caused by exposure to heat, moisture, and road debris. These bushings are engineered with exact tolerances to ensure a snug fit, eliminating unwanted movement and providing consistent handling characteristics.

The manufacturing process employs high-precision molding techniques, resulting in bushings that offer a seamless interface with the control arms. This meticulous construction ensures that your vehicle's suspension geometry remains accurate, promoting even tire wear and optimal handling. The bushings are also resistant to oil and other automotive fluids, further extending their service life and maintaining performance over time.
