Steps to Cut Coil Springs in a Lower Truck

Should I cut coil springs if I want to lower my car?

The Pros of Cutting Coil Springs:

1. Cost-Effective Option:

Cutting coil springs can be a cost-effective way to lower your car compared to purchasing aftermarket lowering springs or a complete coilover suspension kit. It’s an appealing option for those on a budget.

2. Customizable Ride Height:

By cutting the coil springs, you have precise control over how much you want to lower your car. This customization allows you to achieve the desired stance and appearance you’re aiming for.

3. Improved Handling:

Lowering your car’s center of gravity can enhance its cornering stability and handling, making it feel more responsive on the road. This can be especially beneficial for sports car enthusiasts.

4. Aesthetically Pleasing:

A lowered car often has a sleek and aggressive appearance that many car enthusiasts find appealing. It can give your vehicle a unique look and stand out from the crowd.

The Cons of Cutting Coil Springs:

 

1. Safety Concerns:

Safety should be a top priority when modifying your vehicle. Cutting coil springs can compromise the suspension’s ability to absorb bumps and shocks, leading to a rougher ride and potentially affecting your control over the vehicle.

2. Handling and Ride Quality:

While lowering can improve handling, excessive lowering can lead to poor ride quality, increased harshness, and a higher risk of bottoming out on rough roads or speed bumps.

3. Potential for Uneven Lowering:

Cutting coil springs can lead to uneven lowering if not done accurately. This can result in an imbalanced appearance and negatively impact handling.

4. Risk of Bottoming Out:

Lowering your car significantly can increase the risk of the vehicle’s undercarriage, including the exhaust system, scraping or hitting the ground, particularly on uneven or steep surfaces.

5. Legal and Warranty Issues:

Modifying your vehicle’s suspension, including cutting coil springs, may void your warranty and could lead to legal issues if the modification violates local regulations or safety standards.

Is Cutting Coil Springs Right for You?

 

The decision to cut coil springs to lower your car should be made carefully, considering your goals, budget, and the specific characteristics of your vehicle. 

While it offers cost savings and customization options, it also presents safety, ride quality, and handling challenges.

Before proceeding, consult with a professional mechanic or suspension specialist who can provide expert guidance tailored to your vehicle and intended use. 

They can help you explore alternative suspension modifications, such as aftermarket lowering springs or coilover kits, which may provide a safer and more balanced approach to achieving your desired look and performance.

How to cut coil springs to lower a truck?

Lowering a truck by cutting coil springs is a method used to adjust the vehicle’s ride height. However, it’s essential to note that modifying coil springs by cutting them can significantly impact the handling, ride quality, and safety of the vehicle. If done incorrectly, it can lead to an uneven drop, reduced suspension travel, and compromised handling.

If you’re considering this modification, here’s a general guideline:

Required Tools and Materials:

  • Safety goggles and gloves
  • Spring compressor
  • Cutting tool (angle grinder, sawzall, etc.)
  • Measuring tape
  • Marker or paint

Steps:

  1. Safety Precautions:

    • Wear safety goggles and gloves throughout the process.
  2. Measure and Mark:

    • Determine the desired amount to lower the truck and measure this distance from the bottom of the coil spring. Mark this point clearly on the spring with a marker or paint.
  3. Spring Removal:

    • Safely remove the coil springs from the vehicle. Use a spring compressor to compress the spring before removing it from the suspension.
  4. Cutting the Coil Spring:

    • Using an appropriate cutting tool (angle grinder, sawzall, etc.), carefully cut the coil spring at the marked point. Ensure a clean and even cut.
  5. Smoothing the Cut Edge:

    • After cutting, smooth out any rough edges or burrs on the cut end of the spring to prevent potential damage or injuries.
  6. Reinstall the Springs:

    • Place the modified coil springs back into the suspension. Use the spring compressor to re-seat them if necessary.
  7. Test and alignment:

    • Lower the vehicle and check the ride height. Perform a test drive to evaluate the handling and ensure the vehicle remains stable. Consider getting a professional alignment to ensure proper wheel alignment.
