The Lower Suspension Screw M141.5110 is a critical, high-strength fastener engineered for the demanding environment of a vehicle’s suspension system. Specifically designed to secure pivotal components such as control arms, strut assemblies, or trailing links to the chassis or subframe, this screw plays a fundamental role in maintaining proper wheel alignment, handling stability, and overall ride safety. Its failure or degradation can lead to dangerous handling characteristics, uneven tire wear, and significant component damage, underscoring the necessity for a part that meets or exceeds original equipment specifications.

Precision manufacturing defines this component. The designation "M141.5110" provides the exact technical blueprint: a metric 14mm diameter, a fine 1.5mm thread pitch for superior clamping force and vibration resistance, and a 110mm overall length. This screw is typically fabricated from high-grade alloy steel, often grade 10.9 or higher, and undergoes heat-treatment processes to achieve exceptional tensile strength and durability. A corrosion-resistant coating, such as zinc plating or a similar finish, is applied to protect against rust and corrosion caused by road salts, moisture, and environmental contaminants, ensuring long-term reliability.

When selecting a replacement, exact specification matching is non-negotiable. Using an incorrect fastener can compromise the structural integrity of the suspension assembly. This Lower Suspension Screw is sold as a direct OEM replacement, guaranteeing perfect fitment, correct thread engagement, and the required load-bearing capacity. It is an essential purchase for suspension repairs, restoration projects, or performance upgrades where safety and precision are paramount. Always ensure proper installation torque as specified by the vehicle manufacturer to guarantee optimal performance and safety.
