There are three main types of suspension commonly used in vehicles: coil springs, leaf springs, and air suspensions.

• Coil Springs are one of the most common forms of suspension, consisting of helical-shaped metal springs that absorb shocks and vibrations, allowing for a smoother ride.
• Leaf Springs are made up of several layers of curved steel plates attached to the axle and frame providing a stable base on uneven terrain. Leaf spring suspensions are most commonly used in heavier vehicles such as trucks or SUVs.
• Air Suspension systems use air bags instead of metal springs, allowing for an adjustable ride height depending on the terrain. Air suspensions are most commonly used in luxury vehicles and can be adjusted for both comfort and performance.
