The Toyota 4Runner is a legendary SUV, renowned for its off-road capability and rugged reliability. One of the most common modifications enthusiasts undertake is lifting the vehicle. But how many inches should you lift your 4Runner? The answer isn’t a simple number; it depends on your specific needs, budget, and intended use. This article delves into the factors influencing your lift height decision, the pros and cons of different lift sizes, and important considerations to ensure a successful and safe modification.
Understanding the Basics of 4Runner Lifts
Lifting a 4Runner involves increasing the ride height, typically achieved through suspension modifications or body lifts. This allows for larger tires, improved ground clearance, and a more aggressive appearance. However, it’s crucial to understand the implications of different lift heights before making a decision.
Types of Lifts
Two primary types of lifts are commonly used on 4Runners: suspension lifts and body lifts.
A suspension lift replaces or modifies the suspension components, such as springs, shocks, and control arms. This method directly affects the vehicle’s handling and articulation, providing a more significant improvement in off-road performance. Suspension lifts generally offer a more comprehensive upgrade than body lifts, but they often come with a higher price tag.
A body lift, on the other hand, involves raising the body of the vehicle relative to the frame. This is achieved by installing spacers between the body and the frame. Body lifts are typically less expensive than suspension lifts and easier to install. However, they primarily improve aesthetics and allow for larger tires, without substantially improving off-road performance or articulation.

Essential Considerations for a Successful 4Runner Lift
Regardless of the lift height you choose, several factors are critical for ensuring a successful and safe modification.
Component Quality
Invest in high-quality lift kits from reputable manufacturers. Avoid cheap, generic kits, as they may compromise safety and performance. Research brands known for their durability and performance in off-road conditions.
Proper Installation
Proper installation is crucial for the safety and performance of your lift kit. If you lack the necessary mechanical skills and tools, hire a professional installer with experience working on 4Runners. Improper installation can lead to premature wear, poor handling, and even safety hazards.
Wheel Alignment
After installing a lift kit, it’s essential to have your 4Runner’s wheel alignment checked and adjusted. Lifting the vehicle changes the suspension geometry, which can affect alignment. A proper wheel alignment ensures optimal handling, tire wear, and fuel economy.
Extended Brake Lines
Lifting a 4Runner can stretch the factory brake lines, potentially causing them to fail. It is often necessary to install extended brake lines to accommodate the increased ride height. This ensures that the brake system functions correctly and safely.
Sway Bar Links
Lifting the vehicle can also affect the angle of the sway bar, potentially reducing its effectiveness. Longer sway bar links may be necessary to restore the sway bar’s optimal geometry and maintain handling stability.
Differential Drop Kit
On 4Runners with independent front suspension (IFS), lifting the vehicle can change the angle of the CV axles, potentially leading to premature wear. A differential drop kit lowers the front differential to reduce the CV axle angles and extend their lifespan.
Body Mount Chop (BMC)
When running larger tires (typically 35 inches or larger) with a lift, you may need to perform a body mount chop (BMC) to prevent tire rubbing against the body mount. This involves cutting and welding the body mount to create more clearance. This is more common with lifts over 3″.
Aftermarket Upper Control Arms (UCAs)
For lifts of 3 inches or more, aftermarket upper control arms (UCAs) are often recommended. UCAs provide increased articulation and allow for proper alignment, especially when running larger tires. They also correct the ball joint angle, preventing binding and premature wear.
Regular Maintenance
After lifting your 4Runner, it’s essential to perform regular maintenance, including checking suspension components, brake lines, and wheel alignment. This helps ensure the longevity and safety of your vehicle.

What are the most common reasons people lift their 4Runners?
Lifting a 4Runner is often done for several reasons, with the primary one being to improve off-road performance. Increasing the ride height provides greater ground clearance, allowing the vehicle to navigate obstacles like rocks, logs, and deep ruts more easily. This increased clearance also reduces the risk of undercarriage damage, a crucial factor when venturing off the beaten path.
Beyond off-road prowess, many owners also lift their 4Runners for aesthetic purposes. A lifted 4Runner has a more aggressive and commanding stance, which appeals to many enthusiasts. This modification allows for the installation of larger tires, further enhancing the visual appeal and contributing to improved off-road traction. The combination of improved capability and enhanced aesthetics makes lifting a 4Runner a popular modification.
What is the ideal lift height for a 4Runner used primarily for daily driving with occasional off-roading?
For a 4Runner primarily used for daily driving with occasional off-roading, a 2-3 inch lift is often considered the sweet spot. This provides a noticeable increase in ground clearance without significantly compromising on-road handling or fuel economy. A moderate lift allows for larger tires to be installed, improving off-road capability while still maintaining a comfortable and practical driving experience for everyday use.
A 2-3 inch lift also minimizes the need for extensive modifications to other vehicle components, such as longer brake lines or aftermarket upper control arms. This keeps the cost of the lift reasonable and reduces the potential for unforeseen issues. This range offers a balance between improved off-road performance and maintaining the 4Runner’s reliability and drivability as a daily driver.
What are the potential drawbacks of lifting a 4Runner?
Lifting a 4Runner, while offering benefits, can also introduce potential drawbacks. Increased ride height raises the vehicle’s center of gravity, potentially impacting on-road handling and stability, especially during cornering. Fuel economy can also be negatively affected due to increased wind resistance and potentially larger, heavier tires.
Additionally, lifting a 4Runner can put added stress on suspension components, potentially leading to premature wear and tear. It’s crucial to ensure that all related components, such as brake lines and control arms, are properly addressed and upgraded if necessary to maintain optimal performance and safety. Furthermore, a significant lift may affect vehicle entry and exit for some passengers.
What type of lift kit is recommended for a 4Runner: spacer lift, body lift, or suspension lift?
The type of lift kit recommended for a 4Runner depends largely on the intended use and budget. Spacer lifts are the most budget-friendly option, providing lift by placing spacers above the coil springs. While simple to install and affordable, they don’t improve ride quality or off-road performance beyond the added ground clearance. They are best suited for primarily aesthetic enhancements.
For improved off-road performance and ride quality, a suspension lift is generally the recommended choice. Suspension lifts replace the factory shocks and springs with longer, more capable components. This not only increases ride height but also improves articulation and damping, resulting in better control and comfort both on and off the road. Body lifts, which lift the body off the frame, are less common but can provide additional clearance without altering suspension geometry significantly.
What is the largest tire size you can fit on a lifted 4Runner, and how does it affect performance?
The largest tire size you can fit on a lifted 4Runner depends on the lift height and the amount of trimming you’re willing to do. With a 2-3 inch lift, many owners can comfortably fit 33-inch tires with minimal or no trimming. However, larger tires, such as 35-inch tires, often require more extensive modifications, including trimming the fenders and potentially re-gearing.
Larger tires can significantly improve off-road traction and capability but can also negatively impact on-road performance. Acceleration and braking distances may be affected, and fuel economy typically decreases due to increased rolling resistance and weight. It’s crucial to consider these trade-offs and choose a tire size that balances performance with practicality.
What other modifications are typically needed after lifting a 4Runner?
After lifting a 4Runner, several other modifications may be necessary to maintain optimal performance and safety. Lengthened brake lines are often required to accommodate the increased suspension travel and prevent damage to the lines during articulation. This is especially important for lifts exceeding 2 inches.
Additionally, aftermarket upper control arms are often recommended to correct the suspension geometry and ensure proper alignment. This prevents premature tire wear and improves handling. Depending on the severity of the lift, a diff drop may also be necessary to reduce the angle of the CV axles and prevent damage. Finally, a wheel alignment is essential to ensure proper handling and tire wear after any suspension modifications.
How does lifting a 4Runner affect the vehicle’s warranty?
Lifting a 4Runner can potentially affect the vehicle’s warranty, although the extent of the impact varies depending on the specific warranty terms and the dealer’s interpretation. Modifications that directly cause a failure are generally not covered under warranty. For example, if a lift kit leads to premature wear on the CV axles, the warranty may not cover the axle replacement.
However, the Magnuson-Moss Warranty Act protects consumers by preventing manufacturers from voiding warranties simply because aftermarket parts are installed. The manufacturer must prove that the aftermarket part caused the failure. To minimize potential warranty issues, it’s advisable to choose reputable lift kits and have them professionally installed. Consult with your dealer to understand their specific policies regarding modifications.
