Body Lift vs. Suspension Lift — What's the Difference?

Body lifts involve installing spacers or blocks between a vehicle's body and frame, effectively raising the body without modifying the suspension or wheels. This type of lift is primarily cosmetic, allowing for larger tires without significantly improving off-road performance.

Suspension lifts, however, involve replacing or extending the springs, shocks, and sometimes the control arms and other components of a vehicle's suspension system. This not only increases the vehicle's height but also enhances its off-road performance by improving ground clearance, articulation, and the ability to use much larger tires.

The main advantage of a body lift is its cost-effectiveness and simplicity. It's less expensive than a suspension lift and doesn't affect the ride quality or handling since the vehicle's suspension geometry remains unchanged. Conversely, suspension lifts, while more expensive and complex to install, offer substantial improvements in vehicle capability, including better handling and stability on rough terrain, and the ability to install larger tires for improved traction and performance.

Body lifts are often limited in how much height they can add, typically no more than three inches, due to safety and aesthetic reasons. Suspension lifts can provide a more significant increase in height, ranging widely from a few inches to over a foot, depending on the vehicle and the type of lift kit used. This makes suspension lifts more versatile for serious off-roading enthusiasts who require maximum ground clearance and suspension articulation.

Installation of a body lift kit can usually be accomplished with basic mechanical skills and tools, as it does not involve altering the vehicle's suspension. Suspension lift kits, however, often require professional installation due to the complexity of the modifications, which can include changes to the suspension, steering geometry, and sometimes the driveline. This can also lead to additional maintenance considerations and adjustments over time.

Choosing between a body lift and a suspension lift depends on the vehicle owner's goals. If the aim is to improve the vehicle's appearance or accommodate slightly larger tires without spending a lot of money, a body lift is a suitable choice. For those looking to enhance off-road capability, ground clearance, and overall performance, a suspension lift is the preferred option, despite its higher cost and complexity.
