The Suspension Spring (36-131228) supports the vehicle’s suspension and maintains correct ride height. Porza coil springs deliver strength, balance, and long-term reliability.
A suspension spring is a key component of a vehicle’s suspension system. It absorbs road shocks, supports vehicle weight, and ensures stability, driving comfort, and proper handling.
A suspension spring should be replaced if it is broken, sagging, or heavily corroded. Common signs include uneven ride height, clunking noises, or reduced driving stability.
There are several types of suspension springs, including: Coil springs, Leaf springs, Air springs. Each type is designed for specific vehicle types and load requirements.
It is strongly recommended to replace suspension springs in pairs (per axle). This ensures balanced handling, even ride height, and optimal safety.
