1. Bilstein 5100 Leveling Kit: Best Overall
In our evaluation, the Bilstein 5100 stands out as the top choice for 5th Gen 4Runner owners who want a lift that maintains or improves ride quality. Its monotube design and digressive valving provide consistent damping whether you’re on pavement or gravel. Owner feedback consistently praises the 5100 for eliminating the factory nose-down rake while keeping body roll in check. The kit uses your factory springs, so you retain stock spring rates, which helps preserve ride comfort. However, installation requires compressing the front springs, which adds complexity and may require professional help for DIYers without a spring compressor.
While the Bilstein 5100 is a premium choice, it may not suit those on a tight budget, as the cost is higher than basic spacer kits. Also, if you plan to add heavy aftermarket bumpers or winches, the stock springs may sag under load. In that case, a full coilover setup might be better. But for most daily drivers and light off-roaders, the 5100 offers an outstanding balance of performance and durability.
- Adjustable ride height with 5 clip positions for precise leveling
- Digressive piston valving for improved on-road handling
- German engineering with zinc-plated finish for corrosion resistance
Pros: Excellent ride quality on and off road; Highly adjustable without replacing springs
Cons: Requires spring compressor for installation, moderate difficulty
2. Toytec Leveling Kit: Best Value
The Toytec Leveling Kit is a popular budget-friendly option for 4Runner owners looking to level their truck without breaking the bank. It uses CNC-machined aluminum spacers that sit on top of the front struts and a smaller spacer for the rear. Based on manufacturer specs and owner feedback, this kit provides a straightforward 2-inch front lift that levels the vehicle and allows for up to 33-inch tires on 5th Gen models. The installation is relatively easy, as you don’t need to compress springs, though you will need to disconnect the sway bar and lower control arms.
However, the ride quality does take a small hit. Because the spacers increase preload on the front springs, the suspension feels firmer, especially over sharp impacts. Some owners report a slightly harsher ride on rough roads. If you prioritize comfort over cost, you might prefer a shock-based system. Also, this kit is not ideal for heavy off-road use where maximum wheel articulation is needed, as spacers limit down travel. For light trails and daily driving, the Toytec kit delivers solid value.
- Affordable polyurethane spacer lift for front and rear
- Includes preloaded spacers for easy bolt-on installation
- No spring compressor needed, DIY-friendly in about 2-3 hours
Pros: Very affordable compared to shock-based kits; Simple installation with basic tools
Cons: Can stiffen ride slightly, especially over bumps
3. ReadyLift Leveling Kit: Best for Off-Road
The ReadyLift Leveling Kit is engineered for 4Runner owners who take their vehicle off-road and want a comprehensive solution. In our research, this kit stands out because it includes a differential drop kit, which lowers the front differential to keep CV axles at a safer angle, reducing the risk of premature wear. It also comes with extended brake line brackets and bump stop spacers, addressing common issues with lifts over 2 inches. Owner feedback indicates that the ride quality remains close to stock, with only a slight increase in firmness.
However, the ReadyLift kit is pricier than simpler spacer lifts, and installation is more involved due to the diff drop. Some owners note that the rear spacer can cause a slight increase in axle wrap on hard acceleration. If you don’t plan to go off-road frequently, the extra cost may not be justified. For serious off-roaders who want a reliable lift that protects CV joints, this is a strong choice.
- Complete kit with front spacers, rear spacers, and differential drop
- Includes extended brake line brackets and bump stop spacers
- Designed to maintain CV axle angles for longevity
Pros: Includes diff drop to reduce CV angle wear; Good for off-road clearance with larger tires
Cons: More expensive than basic spacer kits
4. Daystar Leveling Kit: Best Budget
The Daystar Leveling Kit is the most affordable way to level a 4Runner. It consists of a polyurethane spacer that sits on top of the front strut, providing a 2-inch lift. Based on owner feedback, installation is straightforward, and the kit includes all necessary hardware. For 4Runner owners on a tight budget who just want to eliminate the factory rake and fit slightly larger tires, this kit gets the job done. Many users report satisfactory results for daily driving.
However, there are notable trade-offs. Polyurethane spacers can develop squeaks over time as they compress and shift. The kit only lifts the front, so the rear remains at stock height, which may not fully level the vehicle if your rear has sagged. Additionally, the ride quality becomes firmer, and there is no diff drop, so CV angle wear is a concern for lifted trucks. This kit is best for those who want a temporary or low-cost solution and are okay with some compromises.
- Lowest cost option, polyurethane front spacers only
- Simple design: just spacer and hardware
- Lifts front 2 inches to level with rear
Pros: Very inexpensive, under budget; Easy installation, no spring compressor needed
Cons: Polyurethane can squeak over time; No rear spacer, so slight rake may remain
5. Rough Country Leveling Kit: Popular Choice
Rough Country offers a popular leveling kit that includes both front and rear spacers to achieve a consistent 2-inch front lift and a 1-inch rear lift, fully leveling the 4Runner. Based on our comparison of specs, this kit is made in the USA and backed by a limited lifetime warranty, which adds peace of mind. Installation is similar to other spacer kits, requiring basic mechanical skills. Owner feedback generally praises the ease of installation and the ability to fit 33-inch tires without rubbing.
However, the ride quality is a common complaint. Many owners report a noticeably stiffer ride, especially over potholes and speed bumps. The lack of a diff drop can also lead to accelerated CV joint wear over time. If you prioritize a plush ride, this may not be the best choice. But for those who want a simple, warranty-backed kit for light off-road use and daily driving, it’s a decent option.
- Complete front and rear spacer lift
- Includes rear coil spring spacers for full leveling
- Made in USA with limited lifetime warranty
Pros: Full kit with front and rear spacers; Lifetime warranty on spacers
Cons: Ride quality can be harsh on rough roads
6. Icon Vehicle Dynamics Leveling Kit: Premium Pick
The Icon Vehicle Dynamics Leveling Kit is a premium option for 4Runner enthusiasts who demand the best. The spacers are machined from billet aluminum and feature a durable coating. In our evaluation, this kit is best suited for those already planning to upgrade to Icon’s suspension components, as it integrates seamlessly with their extended travel CV axles and coilovers. Owner feedback highlights the precision fit and the ability to maintain factory ride quality when used with stock shocks.
However, the cost is significantly higher than other spacer kits, and the real benefits are realized only when combined with other Icon components. If you are on a budget or only need a basic level, this is overkill. Also, installation is more complex if you opt for the CV axles. Skip this if you don’t plan to fully build out your suspension. For the serious off-roader with deep pockets, it’s an excellent investment.
- High-quality billet aluminum spacers with corrosion-resistant coating
- Designed to work with Icon's extended travel CV axles for maximum droop
- Includes detailed installation instructions and hardware
Pros: Top-tier build quality and materials; Excellent off-road performance when paired with Icon shocks
Cons: Very expensive, especially with optional CV axles
7. SpyderTrax Leveling Kit: Best for Daily Driving
The SpyderTrax Leveling Kit is a solid middle-ground option for daily drivers who want a subtle level. It uses CNC-machined 6061 aluminum spacers with an anodized finish, which resists corrosion better than polyurethane. Based on owner feedback, the ride quality is better than many other spacer kits, with less harshness over bumps. Installation is straightforward, and the kit includes high-quality hardware.
However, it only lifts the front, so if your rear has sagged, you may need to add a separate rear spacer or new springs to achieve a perfectly level stance. Also, like most spacer lifts, it does not include a diff drop, so CV joint wear is a potential issue over time. This kit is best for owners who primarily drive on paved roads and want a simple, reliable level without breaking the bank. Off-road enthusiasts may want a more comprehensive solution.
- Precision CNC-machined 6061 aluminum spacers
- Anodized finish for corrosion resistance
- Includes all necessary hardware and instructions
Pros: Smooth ride quality for a spacer lift; Good build quality for the price
Cons: Only front lift, no rear spacer included
Frequently Asked Questions
Will a leveling kit affect my 4Runner's ride quality?
It depends on the type of kit. Spacer lifts (like Toytec or Daystar) increase preload on the front springs, resulting in a firmer ride. Shock-based kits like the Bilstein 5100 maintain or improve ride quality due to better damping. In our research, most owners report a slight trade-off in comfort with spacer kits, while shock upgrades often feel better than stock.
Do I need a differential drop when installing a leveling kit?
For lifts over 2 inches, a diff drop is recommended to reduce CV axle angles and prevent premature wear. Kits like ReadyLift include a diff drop. For smaller lifts (1.5-2 inches), many owners skip it without issues, but it’s a safety consideration. We recommend a diff drop for any lift over 2 inches or if you off-road frequently.
Can I fit 33-inch tires with a 2-inch leveling kit?
Yes, a 2-inch front leveling kit typically allows for 33-inch tires (e.g., 285/70R17) on 5th Gen 4Runners with minimal or no rubbing. Some trimming of the front bumper or fender liner may be required, depending on wheel offset. Owner feedback confirms this is a common setup.
What is the difference between a leveling kit and a lift kit?
A leveling kit raises only the front of the vehicle to match the rear, eliminating the factory rake. A lift kit raises both front and rear, often by 3 inches or more, and may include new springs, shocks, and other components. Leveling kits are simpler, cheaper, and maintain a lower center of gravity, while lift kits provide more ground clearance for serious off-roading.
Can I install a leveling kit myself?
Spacer kits that do not require spring compression (e.g., Toytec, Daystar) are DIY-friendly with basic hand tools and a jack. Shock-based kits like Bilstein 5100 require a spring compressor and more mechanical skill. Many owners choose professional installation for shock kits. Always follow the manufacturer’s instructions and safety precautions.
