Whether you're installing a new lift kit or simply want to verify the height of your existing one, accurate measurement is crucial. Incorrect measurements can lead to handling problems, uneven tire wear, and even safety concerns. This guide will walk you from understanding the different measurement points to troubleshooting potential issues.

Understanding Lift Kit Height

A lift kit increases your vehicle's ground clearance. This is achieved by raising the suspension, allowing for larger tires and improved off-road capability. However, knowing the exact lift height is key to optimal performance and safety.

Why Accurate Measurement Matters

Precise measurement ensures your lift kit is installed correctly. Uneven lift can stress the drivetrain and affect handling. Accurate measurements also help diagnose potential problems during or after installation.

Methods for Measuring Lift Kit Height

There are several ways to measure your lift kit height. The best method depends on your vehicle and the tools available.

1. Measuring from the Ground to the Frame/Body

This is the most common method. You'll need a measuring tape and something level to rest the tape on.

Find Your Measurement Points: Identify consistent points on your frame or body, such as the pinch weld (the seam where the body panels meet) or a specific point on the frame rail. These points should be easily accessible and remain consistent throughout the measurement process.
Measure Before Installation: Before installing the lift kit, measure the distance from the ground to your chosen point(s) on both sides of the vehicle. Note these measurements. It is important to take measurements at several points to get a better understanding of your truck's original ride height.
Measure After Installation: After installation, repeat the process using the same measurement points. Subtract the "before" measurement from the "after" measurement to determine the exact lift height on each side.
Check for Consistency: Compare the measurements from both sides of the vehicle. A significant difference indicates a potential installation issue.

Pro Tip: Use a level surface and ensure your vehicle is not loaded to get accurate readings.

2. Using a Measuring Stick and Level

A long, straight measuring stick, combined with a level, provides a more precise method for measuring the lift height.

Secure the Stick: Attach the measuring stick to your vehicle's frame, ensuring it's perfectly level using the level.
Measure to the Ground: Measure the distance from the bottom of the measuring stick to the ground. Repeat this measurement on both sides of the vehicle for consistency.
Compare Measurements: Follow the same steps mentioned above to compare pre and post-installation measurements.

3. Measuring Hub-to-Fender Height

This method measures the distance between the wheel hub and the vehicle's fender. This works well, especially for vehicles with a body lift or a combination lift kit.

Identify the Measurement Point: Choose a consistent point on the wheel hub. This might be the top of the hub. On the fender, find a stable, easily accessible point.
Measure Before and After: Measure the distance between these points before and after the lift kit installation.
Check for Consistency: This is the same method as previously mentioned and ensures that the measurements from both sides of the vehicle are consistent.

Troubleshooting Measurement Discrepancies

If your measurements are inconsistent, several factors could be at play:

Uneven Installation: Check that the lift kit components are installed correctly and evenly on both sides of the vehicle.
Incorrect Components: Verify that you have the correct lift kit components for your specific vehicle make and model.
Suspension Issues: Issues like worn-out shocks or springs can affect the measurement.
Vehicle Load: Make sure the vehicle is unloaded when taking measurements.

Conclusion

Measuring your lift kit height accurately is critical for safe and optimal performance. By following the methods outlined above, and by understanding the common sources of measurement discrepancies, you can ensure your lift kit is installed correctly and providing the intended ground clearance. Remember to always consult your lift kit's instructions for specific measurement guidelines. If you're unsure about any aspect of the installation or measurement process, consult a professional mechanic.
