The main components of the automotive coil spring gasket lifting kit include: coil springs, shock absorbers, spring gaskets (upper/lower gaskets), spring seats, bearings, top rubber, and fixing nuts, etc.By adjusting the relative positions of the springs and shock absorbers, the suspension geometry and ground clearance of the vehicle can be changed.

Core Function 

Increase ground clearance: The physical thickness of the spacer directly raises the vehicle body, enhancing the vehicle's ability to traverse unpaved roads and reducing the risk of chassis scratches. 

Prevent contact between shock absorbers and the vehicle body: During suspension compression, raising the spacer can prevent the shock absorber piston rod from directly colliding with vehicle components, protecting the shock absorber and the vehicle structure, and extending their lifespan. 

Optimize suspension performance: By adjusting the spring preload, it is possible to improve the suspension response characteristics, reduce the impact of bumps on the shock absorber system, and enhance driving stability. 

Potential impacts and precautions 

Comfort and handling: A moderate increase can enhance the passability, but excessive heightening may alter the suspension angle, affecting the tire grip and steering accuracy. Professional tuning is required. 

Load capacity: The spacer itself does not increase the bearing limit of the spring; it only optimizes the existing suspension working range through geometric adjustments. 

Installation compatibility: Ensure that the spacer matches the spring and shock absorber to avoid abnormal noises or loose connecting parts due to improper installation. 

Such kits are commonly found in off-road or modification scenarios, aiming to balance the improvement of passability with the stability of daily driving. However, the specific effect should be evaluated based on the vehicle model and usage conditions.
