• Wire Diameter: Uniform across the entire length, ensuring predictable stiffness and durability.
• Coil Count: Optimized number of turns for a balanced compromise between ride comfort and road holding.
• Load Capacity: Designed to handle typical passenger vehicle weight ranges while maintaining structural integrity under dynamic loads.
• Compatibility: Specifically engineered for the front suspension assemblies of Peugeot 307 (various trims: 3A/C, 3H, 3E) and Citroën C4 (C4 I, C4 Coupe, SW, Break).

Performance Benefits

The Monroe SE3391 Coil Spring delivers a host of performance advantages that enhance both daily driving comfort and spirited driving dynamics:

• Improved Road Holding: The spring’s precise stiffness profile reduces body roll during cornering, providing tighter handling.
• Enhanced Ride Comfort: Its balanced compression characteristics absorb road irregularities effectively, minimizing harshness transmitted to occupants.
• Durability and Longevity: High‑grade alloy steel combined with meticulous heat treatment ensures resistance to fatigue, corrosion, and wear over extended mileage.
• Consistent Performance: The constant wire diameter guarantees uniform spring rate throughout its travel, preventing unpredictable behavior under load.

Installation Overview

Installing the Monroe SE3391 Coil Spring is a straightforward process that can be completed with standard automotive tools. Below is an outline of the typical installation steps for front suspension assemblies:

1. Preparation: Secure the vehicle on a lift or jack stands, ensuring it is level and stable.
2. Remove Existing Spring: Detach the old coil spring by loosening the mounting bolts or retaining clips. Carefully release the spring from its housing.
3. Position New Spring: Align the Monroe SE3391 Coil Spring with the suspension geometry, ensuring correct orientation relative to the steering knuckle and control arm.
4. Secure Mounting Points: Tighten all bolts or clips according to manufacturer torque specifications. Verify that the spring is seated properly without any misalignment.
5. Recheck Alignment: Inspect suspension geometry, wheel alignment, and steering components for proper setup before lowering the vehicle.

Maintenance Tips

• Regular Inspection: Periodically check for signs of wear such as uneven compression or visible damage to the spring coils.
• Lubrication: Apply a light coating of high‑temperature grease at pivot points and mounting surfaces to reduce friction and prevent corrosion.
• Tire Pressure Management: Maintain recommended tire pressures to avoid excessive load on the suspension system, which can accelerate wear.
