How to lower a truck with leaf springs?
Lowering a truck can enhance its appearance, improve handling, and provide a custom look that many truck enthusiasts desire. One common method for lowering a truck is by modifying its leaf spring suspension system. In this guide, we’ll walk you through the process of lowering a truck with leaf springs, ensuring you understand the steps and considerations involved.
What Are Leaf Springs?
Leaf springs are a type of suspension system commonly found in trucks and older vehicles. They consist of multiple layers of metal (leaves) stacked together to absorb shocks and support the vehicle's weight. Modifying the leaf springs can adjust the truck's ride height, either raising or lowering it.
Why Lower a Truck with Leaf Springs?
There are several reasons why truck owners choose to lower their vehicles:
- Improved aesthetics: A lowered truck often has a sleeker, more aggressive look.
- Better handling: Lowering the center of gravity can enhance stability and cornering performance.
- Customization: It allows owners to personalize their trucks to match their style.
Steps to Lower a Truck with Leaf Springs
Lowering a truck with leaf springs requires careful planning and the right tools. Follow these steps to achieve the desired result:
- Step 1: Gather the necessary tools and materials.
You’ll need a jack, jack stands, wrenches, a socket set, and lowering blocks or a leaf spring modification kit. Ensure you have safety equipment like gloves and safety glasses.
- Step 2: Safely lift the truck.

As the owner of Kevin's Autos, an auto service shop with years of experience in car maintenance and repair, I'm often asked about ways to lower a truck with leaf springs. Lowering your truck can not only improve its appearance but also enhance its handling and performance. In this article, I'll guide you through the process of lowering a truck with leaf springs, providing step-by-step instructions and important considerations to keep in mind.
Reasons to Lower a Truck with Leaf Springs
There are several reasons why you might want to lower your truck with leaf springs:
- Improved Appearance: Lowering your truck can give it a sleeker, more aggressive look, enhancing its overall aesthetic appeal.
- Enhanced Handling: Lowering the center of gravity can improve the truck's handling, making it more responsive and stable during cornering and high-speed maneuvers.
- Increased Fuel Efficiency: A lower ride height can reduce wind resistance, potentially leading to improved fuel efficiency.
- Customization: Lowering your truck allows you to personalize its appearance and performance to your liking, reflecting your unique style and preferences.
Steps to Lower a Truck with Leaf Springs
Lowering a truck with leaf springs can be a straightforward process, but it's important to follow the steps carefully to ensure a safe and successful outcome. Here's a step-by-step guide:
- Measure the Current Ride Height: Start by measuring the current ride height of your truck, taking measurements from the ground to the bottom of the fender well. This will help you determine the desired amount of lowering.
- Obtain the Necessary Parts: Depending on the desired lowering amount, you may need to purchase new leaf springs, shackles, or other components. Consult with a professional or refer to your truck's manufacturer specifications to ensure you get the right parts.
- Safely Lift the Truck: Use a jack and jack stands to safely lift the truck and gain access to the leaf springs. Ensure the vehicle is securely supported before proceeding.
- Remove the Leaf Springs: Carefully remove the leaf springs, taking note of their orientation and any spacers or shims that may be present.
- Install the New Leaf Springs: Install the new, shorter leaf springs, ensuring they are properly aligned and secured. You may need to adjust the shackles or add spacers to achieve the desired ride height.
- Lower the Truck: Slowly lower the truck back down, ensuring the new leaf springs are properly seated and the suspension is functioning correctly.
- Test and Adjust: Take the truck for a test drive and make any necessary adjustments to the ride height or suspension components to achieve the desired handling and performance characteristics.
Important Considerations
When lowering a truck with leaf springs, there are a few important considerations to keep in mind:
- Wheel Clearance: Ensure that the lowered truck still has adequate wheel clearance to prevent rubbing or interference with the suspension components.
- Suspension Geometry: Lowering the truck can affect the suspension geometry, potentially leading to changes in handling, braking, and tire wear. Consult with a professional to ensure the modifications are properly executed.
- Legality and Safety: Ensure that the lowered truck still meets all applicable legal requirements and safety standards in your area. Consult with local authorities or a professional if you have any concerns.
- Maintenance and Inspection: Regularly inspect the lowered suspension components and perform any necessary maintenance to ensure the truck's continued safe and reliable operation.
Lowering a truck with leaf springs can be a rewarding project, but it's important to approach it with care and attention to detail. By following the steps outlined in this article and considering the important factors, you can successfully lower your truck and enjoy the improved appearance, handling, and performance.
Frequently Asked Questions
What is the easiest way to lower a truck?
Rear Flip Kits
If you're going for a more dramatic drop on your truck, a flip kit is a cheap and easy way to accomplish this. Rear axles are factory mounted under leaf springs and these brackets allow you to flip it all.
Does lowering a truck affect ride quality?
Lowering your car or truck so it's closer to the ground is a popular way to customize your ride. Done right, it's a great look that also boosts handling performance. Done wrong, it could compromise handling, drivability and traction, reduce tire tread life and even damage parts.
What is the alternative to lowering springs?
Air suspension replaces the factory springs, struts, and shocks with air struts. These air struts have rubber bladders mounted to the struts that inflate and deflate to raise and lower the vehicle. You can adjust your ride height at any time, and with some advanced kits, from outside of your vehicle with your phone.
Can you cut springs to lower a truck?
A stiffer spring will help reduce bottoming out. A safe place to start is by measuring how much you want to lower the vehicle. Then cut 1/2 that measurement off the length of the springs and reinstall them. Then take her for a drive, and drive it like you stole it to get the springs well worked and seated properly.
How much does it cost to lower my truck?
Lowering spring kits go for anywhere between $100 and $700. A professional installation may cost an additional $200 to $800. If your vehicle needs a spring compressor to install lowering springs, it's much safer to bring it to a trusted auto shop.
How can I make my leaf spring truck ride better?
Five Keys To A Good Leaf Spring Suspension
- Use Multi-Leaf Springs. Rule number one for making a good leaf spring suspension is the use of multi leaf springs.
- Roll and Taper Your Leaf Ends.
- Never Adjust Your Ride Height With Blocks.
- Make Sure Your Shackle's Angled Right.
- Choose The Right Shock.
What does flipping your leaf springs do?
It brings the axle and wheels closer to the chassis (essentially drops the body) by 5 inches—and in some instances possibly 1 or 2 more—depending on spring thickness.
Can you put axle under leaf springs?
The leaf springs allow a full range of travel. When installing the axle under the spring, the Axle Plate first requires a slight fold in the center as shown in picture. The fold can be achieved with a hydraulic press or a vice and something to leverage.
How to lower a truck that has leaf springs?
There are a variety of ways to lower a truck with leaf springs. In most cases, you can accomplish the task with a winch or a low boy trailer. If you do not have access to these tools, you can use straps and blocks to lower the truck.
Can I lower my stock springs?
Installing Lowering Springs on Stock Shocks and Struts
While this can be a cost-effective approach, it's essential to be aware of potential drawbacks. Stock shocks may not be optimized for the different dynamics introduced by lowering springs, leading to suboptimal performance and increased wear over time.
