Difference between a Body Lift Kit and a Suspension Lift Kit

When it comes to modifying vehicles for better ground clearance or enhanced aesthetics, two popular options are body lift kits and suspension lift kits.

These kits serve the same purpose—to raise the height of your vehicle—but the way they achieve this goal and their impact on performance differ.

In this article, we’ll explore the differences between body lift kits and suspension lift kits, breaking down their pros, cons, and ideal applications.

What is a Body Lift Kit?

A body lift kit essentially raises the body of the vehicle away from the frame. It involves installing a series of spacers (usually made of a durable material like polyurethane) between the body and the vehicle’s frame.

These spacers elevate the body, providing space for larger wheels and tires without altering the suspension geometry.

Pros of Body Lift Kits

1. Cost-Effective: Body lift kits are generally less expensive than suspension lift kits.
2. Ease of Installation: These kits can be easier to install, often not requiring extensive changes to the vehicle’s existing structure.
3. Preserved Ride Quality: Since they don’t alter the suspension, body lift kits maintain the factory ride quality.
4. Cosmetic Boost: They can provide the “lifted” look without affecting the vehicle’s handling.

Cons of Body Lift Kits

1. Limited Lift: You can usually raise the vehicle only up to 3 inches using a body lift kit.
2. Gaping: The space between the body and the frame becomes visible, which some people find unattractive.
3. No Performance Enhancements: They don’t offer improved off-road capabilities.

What is a Suspension Lift Kit?

A suspension lift kit, on the other hand, replaces or modifies the components of a vehicle’s suspension system to raise the height. This type of lift usually involves swapping out shocks, springs, control arms, and other suspension components for taller, more robust versions.

Pros of Suspension Lift Kits

1. Increased Ground Clearance: These kits provide significantly more ground clearance compared to body lift kits.
2. Improved Off-Road Performance: With a suspension lift, you’ll get enhanced suspension articulation, which is crucial for off-roading.
3. Greater Lift: Suspension lifts can raise a vehicle by as much as 12 inches or even more.
4. Better Shock Absorption: Upgraded shocks and springs can improve ride comfort, especially over rough terrains.

Cons of Suspension Lift Kits

1. Costly: These kits can be expensive, both in terms of parts and labor.
2. Complex Installation: Professional installation is often recommended due to the complexity involved.
3. Potential Warranty Issues: Modifying the suspension might void your vehicle’s warranty.
4. Reduced Fuel Efficiency: The greater height and weight can reduce your vehicle’s miles-per-gallon (MPG) rating.

Comparative Factors

Complexity

• Body Lift: Less complex, easier to reverse.
• Suspension Lift: More complex, often requiring specialized skills for installation and tuning.

Aesthetics vs Performance

• Body Lift: More for aesthetics, less for performance.
• Suspension Lift: Designed for both aesthetic and performance enhancements.

Cost

• Body Lift: Generally more affordable.
• Suspension Lift: More expensive due to component costs and labor.

Ideal Applications

• Body Lift: Best for those looking for a less expensive lift for mostly cosmetic reasons.
• Suspension Lift: Best for serious off-road enthusiasts who need greater ground clearance and improved suspension articulation.

Conclusion

Both body lift kits and suspension lift kits have their pros and cons, and the best choice depends on what you’re looking to achieve. If you want a minor lift without a significant investment, a body lift kit may be the way to go.

On the other hand, if you’re an off-road enthusiast looking for maximum performance, a suspension lift kit will better meet your needs.

Always consider your driving habits, your vehicle’s intended use, and your budget when choosing between these two options.
