Description
Product Overview
The Prothane 7-402-BL sway bar link kit is a premium replacement designed for vehicles that demand both durability and refined handling. Each link is fabricated from high‑grade polyurethane, a material chosen for its excellent wear resistance, low friction, and ability to retain lubrication over the life of the part. Precision machining guarantees a factory‑exact fit, eliminating the need for modifications. The kit includes two links, each pre‑filled with super grease to ensure silent operation from the first mile. With a lightweight construction of just 0.01 ounces per link, the kit adds minimal unsprung weight while delivering the necessary rigidity to keep your sway bar effective during aggressive cornering or everyday driving.
Usage
This sway bar link kit is ideal for a wide range of applications, from daily commuters seeking reduced chassis noise to performance enthusiasts looking to sharpen handling dynamics. Install the links on any standard sway bar that matches the OEM specifications for the 7-402-BL model number. The kit performs exceptionally well in varied climates, maintaining its elasticity in cold weather and resisting degradation under high heat. Whether you are upgrading a compact sedan, a sporty coupe, or a light‑truck suspension, the Prothane links provide consistent performance on city streets, winding mountain roads, and track days.
