Lesjöfors 4295874 Suspension Spring

Lesjöfors 4295874 Suspension Spring

The Lesjöfors 4295874 Suspension Spring is a high‑performance coil spring engineered for the rear axle of Volvo vehicles, particularly the XC70 II Kombi (136) model. Designed with precision and durability in mind, this component plays a critical role in maintaining vehicle stability, ride comfort, and handling dynamics.

Key Design Features

• Helical Construction: The spring’s helical shape provides smooth load distribution and consistent rebound characteristics across a wide range of operating conditions.
• Optimized Wire Diameter: A carefully selected wire diameter balances strength with flexibility, ensuring the spring can absorb road irregularities while resisting fatigue over time.
• Precision Tolerances: Tight manufacturing tolerances guarantee that each spring fits its mounting points accurately, reducing play and enhancing overall suspension performance.
• Corrosion‑Resistant Finish: A protective coating safeguards the spring against environmental factors such as moisture, road salt, and temperature fluctuations.

Performance Characteristics

The Lesjöfors 4295874 is engineered to deliver a balanced ride quality, offering both comfort for everyday driving and sufficient stiffness for spirited handling. Its load‑deflection curve has been calibrated to match the original specifications of the Volvo XC70 II, ensuring that the vehicle’s suspension geometry remains intact.

Key performance metrics include:

• Spring Rate: A moderate spring rate that supports typical passenger and cargo loads without compromising ride softness.
• Deflection Range: Adequate travel to accommodate road irregularities while preventing bottoming out under heavy load conditions.
• Fatigue Life: Designed for a long service life, the spring can withstand thousands of cycles before any noticeable degradation occurs.

Installation and Compatibility

The Lesjöfors 4295874 is fully compatible with the rear suspension assembly of the Volvo XC70 II Kombi (136). It is a direct replacement for the original coil spring, meaning that no additional modifications are required. Installation involves:

1. Removing the existing spring and associated mounting hardware.
2. Aligning the new spring with the mounting points on the rear axle.
3. Securing the spring using the supplied bolts or retaining clips, ensuring proper torque specifications are met.

Because the spring is a direct fit, technicians can complete the replacement in a single service visit, minimizing downtime and labor costs.

Material Composition

The spring is constructed from high‑strength steel alloy, chosen for its excellent tensile properties and resistance to metal fatigue. The alloy composition typically includes:

• Carbon (C) – enhances hardness and strength.
• Manganese (Mn) – improves toughness.
• Silicon (Si) – contributes to wear resistance.

These elements work together to produce a spring that can endure the dynamic stresses of daily driving while maintaining its structural integrity over many years.

Maintenance Tips

• Regularly inspect the spring for signs of wear, such as visible cracks or excessive deformation.
• Check mounting bolts and retaining clips for tightness; loose fasteners can lead to premature failure.
• Avoid overloading the vehicle beyond its specified payload capacity to preserve spring life.
