Suspension Systems: Magneti Marelli Parts & Services expands its offering with shock absorber accessory kits and stabilizer links

When servicing a suspension system, replacing only the main component is not always sufficient to restore the vehicle’s proper dynamic behavior. Ride comfort, steering precision, stability, and the long-term durability of the repair depend on the efficiency of all elements within the suspension system and on the correct balance between its various components.

With this approach, Magneti Marelli Parts & Services is expanding its aftermarket offering by introducing a new range of stabilizer links while further strengthening its portfolio of shock absorber accessory kits, thus providing distributors, wholesalers, and workshops with an increasingly comprehensive solution for professional suspension maintenance.

The goal is to offer aftermarket professionals an integrated product range in which complementary components contribute to restoring the vehicle dynamics intended by the manufacturer, while simplifying spare parts management through a single supplier.

— Shock absorber accessory kits: much more than simple complementary components

During shock absorber replacement, attention inevitably focuses on the main component. However, mounting supports, bearings, bump stops, and dust boots are also subject to suspension loads and environmental factors and may reach levels of wear that can compromise the performance of the entire system.

For this reason, Magneti Marelli Parts & Services offers a complete range of accessory kits to complement its shock absorber line. Their replacement is recommended alongside shock absorber replacement, whenever these components are worn, or whenever specified by maintenance procedures. This intervention helps restore ride comfort, steering accuracy, vibration isolation, and the durability of newly installed components.

The kits include components that perform specific functions within the suspension system. Shock absorber mounts help absorb vibrations and noise transmitted to the vehicle body; support bearings facilitate smooth rotation of the McPherson strut during steering; bump stops absorb and limit loads under maximum shock absorber compression, protecting suspension components from impact forces; while dust boots shield the rod and oil seal from water, dust, and other contaminants, helping prevent premature seal wear and the risk of oil leakage.

For workshops, replacing these components at the same time as the shock absorbers represents a best practice in maintenance that helps preserve suspension efficiency over time and reduces the risk of future repairs caused by already deteriorated parts remaining in service.

Mounting kits and shock absorber mounts from Magneti Marelli Parts & Services undergo compression and pull-out resistance testing, adhesion and durability tests, as well as tightening torque verification, supporting long-lasting performance and repeatable installation procedures in the workshop.

— Accurate diagnosis: the first step toward an effective repair

Knocking noises from the front axle when driving over uneven surfaces, noise when steering, abnormal vibrations, excessive play in the joints, or reduced stability during lane changes and load transfers can all be caused by wear in one or more suspension components.

When these symptoms occur, it is important to inspect not only the shock absorbers but also their related accessories and connecting elements. A comprehensive diagnosis helps identify the root cause more accurately and allows workshops to plan a truly effective repair, preventing worn components from compromising the performance of newly installed parts.

— Stabilizer links: a key component in vehicle dynamics

While shock absorbers and accessory kits play a fundamental role in controlling vehicle vertical movement, stabilizer links are equally important. These components connect the stabilizer bar to the suspension system, ensuring the correct transfer of forces during vehicle operation.

Although often considered secondary components, stabilizer links have a significant impact on vehicle dynamics. Wear in the ball joints or connecting elements may result in noise, excessive play, reduced steering precision, and diminished effectiveness of the stabilizer bar in limiting body roll during cornering and rapid direction changes.

To meet these requirements, Magneti Marelli Parts & Services introduces a range of stabilizer links for passenger cars and commercial vehicles, developed to provide extensive coverage of the European vehicle parc and continuously updated to reflect the evolution of the market.

— Solutions Developed According to Vehicle Manufacturer Specifications

The range is manufactured in IATF 16949-certified facilities, the international standard for quality management systems in the automotive industry, and follows a design approach focused on compliance with the specifications defined by vehicle manufacturers for each application.

Materials, geometries, and construction solutions are determined according to the characteristics of the original application, with the aim of facilitating correct installation and ensuring performance consistent with the vehicle manufacturer's requirements.

For certain applications, this includes the use of PA66-GF30, a structural engineering polymer based on polyamide reinforced with 30% glass fiber, employed whenever required by the vehicle’s original configuration. This technical solution is widely used in original equipment by numerous vehicle manufacturers and selected to ensure compliance with design specifications.

The use of different materials within the same product family should not be viewed as an upgrade or downgrade in quality. Rather, it reflects the intention to comply with the design requirements defined for each specific vehicle. For aftermarket professionals, this means being able to install a component that is technically consistent with the original application.

— Durability designed for real operating conditions

Particular attention has also been paid to the factors that influence component durability under actual operating conditions.

The ball pins undergo dedicated heat-treatment processes designed to achieve the optimal balance between surface hardness and material toughness, two essential characteristics for ensuring reliability and resistance to the stresses that suspension systems face every day.

Corrosion protection is ensured through dedicated coatings and an electrophoretic deposition process (e-coating), providing highly uniform coverage and protecting even areas that are difficult to reach with conventional treatments.

The range is also subjected to salt spray testing for up to 720 hours, demonstrating the attention devoted to protecting components that operate in environments exposed to humidity, water, road salt, and contaminants.

Corrosion is not merely an aesthetic issue. Over time, it can impair proper joint operation, complicate removal procedures, and accelerate overall component degradation. For this reason, the quality of surface treatments is an important factor when selecting replacement parts.

— A product range designed for professional suspension maintenance

With the introduction of the new stabilizer links, the Magneti Marelli Parts & Services suspension range expands further, complementing its shock absorber accessory kits alongside the already established control arm portfolio.

The objective is not simply to broaden the catalogue, but to provide workshops, wholesalers, and distributors with a technically consistent offering tailored to the needs of professional maintenance, supporting comprehensive repairs that remain aligned with the vehicle’s original engineering characteristics.

A range developed to support aftermarket professionals in addressing a wide variety of repair requirements, with components engineered according to vehicle manufacturer specifications and continuously updated to reflect the evolution of the vehicle parc.
