Introduction With Leaf Springs & Coil Springs
Leaf springs and coil springs are two of the most common suspension systems used in vehicles today.
Leaf spring suspension was the first type of suspension used in automobiles. It is a simple design consisting of several thin metal leaves stacked on top of one another. These leaves flex as the vehicle experiences a bump in the road, absorbing the shock and providing a smooth ride.
Coil spring suspension is a newer, more advanced design. Instead of metal leaves, it uses a series of coil springs to absorb the shock. Coil spring suspension is more durable and provides better handling than leaf springs.
Both suspension systems have their pros and cons, but understanding the differences between the two can help you make an informed decision when choosing a vehicle or upgrading your suspension.
Why Do You Convert Leaf Springs to Coil Springs?
We already discussed above that leaf springs and coil springs are two different types of suspension systems used in vehicles. Leaf springs are typically used in older or heavier vehicles, while coil springs are more commonly used in modern cars.
There are several reasons why someone might want to convert their vehicle from leaf springs to coil springs.
One reason is that coil springs are generally considered to be more comfortable and provide a smoother ride than leaf springs. Coil springs also have more options for customization, allowing for greater control over the suspension system.
Another reason to convert from leaf springs to coil springs is to improve the handling and performance of the vehicle. Coil springs offer better handling characteristics, allowing for better cornering and stability. They also provide more consistent suspension performance, making it easier to tune the suspension to specific driving conditions.
Converting from leaf springs to coil springs can also result in weight savings, which can improve fuel efficiency and overall performance. Leaf springs can be quite heavy, while coil springs are typically much lighter.
Overall, converting from leaf springs to coil springs can offer several benefits in terms of comfort, performance, and weight savings. However, it is important to consult with a qualified mechanic or suspension specialist to ensure that the conversion is done properly and safely.

The process of converting from leaf springs to coil springs is complex and time-consuming, necessitating the services of a professional. Given this data, the following are the necessary steps:
Research and planning
The conversion procedure should be well-researched and planned out before any work is started. Expert mechanics or suspension technicians may need to be consulted to ensure the conversion can be done safely.
Remove the old suspension components
The first step is to get rid of the old suspension parts. This includes the leaf springs, shackles, U-bolts, and any other hardware that came with them.
Design and fabricate new suspension components
Until the chassis body design is changed, the leaf spring cannot be replaced by a coil spring. Changing from leaf springs to coil springs necessitates a redesign of the suspension system. The frame and chassis need to be modified to suit the new suspension in addition to designing and fabricating new mounts for the coil springs and a new control arm and steering linkage system.
Choose the right coil springs
Coil springs are available in a variety of sizes and spring rates; pick the ones that are most suited to your vehicle’s weight and intended use. To do this, you may need to use a spring rate and length calculator or speak with a suspension expert.
Install the new suspension system
Once all of the new parts have been planned and built, it is time to install the new suspension system. This entails affixing the replacement control arm and steering linkage system, installing the new coil spring mounts, and securing all hardware per the manufacturer’s guidelines.
kingpin in wheel alignment
A kingpin is a pivoting joint that connects the wheel spindle to the axle beam in some suspension systems. It helps control how the wheel moves and holds up the weight of the car. When going from leaf springs to coil springs, a kingpin may be needed to give the new suspension parts a stable place to be mounted.
Test and adjust the new suspension
After the new suspension system has been installed, it must be tested and adjusted to ensure that it is functioning properly. To achieve this goal, modifications to the vehicle’s spring rate, wheel alignment, and other parts may be necessary.
