Ford Focus Mk3 Rear Coil Spring Left Right N/O/S Yellow Red Blue 1741766 SET

Ford Focus Mk3 Rear Coil Spring Left Right N/O/S Yellow Red Blue SET is a complete pair of suspension components designed for the rear axle, mounted on both the left and right sides. The set with color markings (yellow, red, blue) allows for precise identification of the correct variant for a specific suspension version, which facilitates part selection and ensures consistent performance of the chassis system. By maintaining the factory spring characteristics, the suspension remains predictable and stable during daily operation.

Purpose and function in the suspension

The set of rear coil springs for the Ford Focus Mk3 Rear Coil Spring Left Right N/O/S Yellow Red Blue SET operates on the rear axle, on both the left and right sides, responsible for maintaining the correct vehicle ride height and damping comfort. These components work in conjunction with the shock absorbers, stabilizing the vehicle during acceleration, braking, and cornering. Using a pair of springs from the same set allows for maintaining an even load on both sides of the vehicle and reduces the risk of unwanted tilting.

Technical characteristics of the set

The springs belong to the Leaf and coil springs group, meaning they are load-bearing components of the suspension system, transferring loads from the body to the wheels. Color markings (yellow, red, blue) are applied at the factory by the manufacturer to distinguish spring characteristics, such as stiffness or suitability for a specific vehicle configuration. This makes it possible to maintain compliance with the original suspension specifications of a given Focus Mk3 unit. As an original Ford component, the set is designed for proper fitment into mounting seats and compatibility with stock suspension components. The appropriate shape and coil geometry influence the linear and predictable operation of the spring throughout the full range of deflection, which translates into stable vehicle handling.

Benefits of using original rear springs

Using factory springs on the rear axle of the Focus Mk3 allows for maintaining the original vehicle handling characteristics, without unwanted changes in suspension height or ride comfort. Replacing both elements as a pair minimizes differences in stiffness between the left and right sides, which is particularly important during dynamic driving and when driving with a load. Properly selected springs also help reduce excessive wear on other suspension components, such as shock absorbers or bushings. The used condition of the set allows for an economical repair of the chassis system while maintaining the original design and fitment. This solution is particularly beneficial for post-accident repairs or restoring the vehicle to factory parameters after previous suspension modifications.

Professional selection and installation

To fully utilize the potential of the rear spring set, installation in a specialized workshop is recommended, using appropriate spring compressor tools and performing a suspension geometry check after replacement. Correct seating in the mounts and checking the condition of mounts, bump stops, and shock absorbers help avoid unwanted noises and uneven wear. Selection in accordance with color markings is crucial for maintaining factory suspension performance parameters.
