Lift Kits: Understanding the Discrepancy in Advertised Height and Actual Thickness

Posted by Autofly Inc on

Lift kits have become increasingly popular among off-road enthusiasts and truck owners looking to enhance their vehicle's appearance and capabilities. However, it is important to understand that lift kits are not always the same thickness as the advertised height. This article aims to shed light on the reasons behind this discrepancy and provide insights into the factors that affect the actual lift height achieved.

Suspension Geometry and Design:

One of the primary reasons why lift kits may not provide the exact advertised height is due to suspension geometry and design. Vehicle manufacturers design their suspension systems with specific components and measurements to maintain optimal performance and handling. Aftermarket lift kits alter this geometry by replacing or modifying certain suspension components. The resulting changes can impact the actual lift height achieved.

Vehicle Weight and Load:

The weight of your vehicle and any additional cargo or accessories can affect the actual lift height achieved with a lift kit. The added weight compresses the suspension, causing it to settle and reducing the overall lift height. It's important to consider the weight and load distribution of your vehicle when estimating the lift height.

Spring Compression and Settling:

Lift kits typically include new coil springs or coil spacers that contribute to the increased ride height. However, these springs may compress over time or settle under the vehicle's weight, leading to a slight decrease in the lift height. It is crucial to allow sufficient time for the springs to settle and reach their final height before assessing the actual lift achieved.

Suspension Flex and Articulation:

Off-road enthusiasts often prioritize improved suspension flex and articulation for enhanced off-road capabilities. Lift kits designed for off-roading may prioritize these factors over achieving the exact advertised height. As a result, the lift kit may provide a slightly lower height to allow for better suspension travel and articulation on uneven terrain.

Tire Size and Wheel Offset:

The choice of tire size and wheel offset can significantly impact the perceived lift height. Larger tires can visually enhance the appearance of a lifted vehicle, but they may also reduce the overall clearance and lift height. Additionally, the wheel offset affects the positioning of the tires in relation to the vehicle's body, influencing the perceived lift.

Installation and Adjustment:

The installation process and proper adjustment of the lift kit play a crucial role in achieving the desired lift height. Improper installation or lack of adjustment can lead to inconsistencies in the lift height. It is essential to follow the manufacturer's instructions carefully and, if needed, seek professional assistance to ensure accurate installation and adjustment.


When considering a lift kit for your vehicle, it is important to understand that the advertised height may not always correspond directly to the actual thickness achieved. Suspension geometry, vehicle weight, spring compression, suspension flex, tire size, wheel offset, and installation all contribute to the final lift height. By having a clear understanding of these factors, you can make informed decisions and manage your expectations regarding the actual lift height achieved with a lift kit. Consulting with experienced professionals or knowledgeable enthusiasts can also provide valuable insights and guidance in selecting the right lift kit for your specific needs.
