Why Toyota 4Runner?

The Toyota 4Runner stands as a symbol of durability and versatility in the SUV market. With its body-on-frame construction, it's one of the few remaining vehicles designed to handle both the daily commute and adventurous off-roading. Its popularity among enthusiasts stems from its capability to be transformed into an even more robust machine. ICON suspension upgrades are tailored to meet the 4Runner's unique specifications, ensuring that enhancements complement the vehicle's inherent strengths. 

By choosing to upgrade a Toyota 4Runner, owners are not only investing in a reliable and rugged vehicle but also in the potential to unlock superior performance that aligns with the adventurous spirit of the 4Runner community.

ICON Stage 1 Suspension System

Features & Benefits

The ICON Stage 1 Suspension System for the Toyota 4Runner is engineered to offer a significant leap in performance over the stock setup. This system features high-quality coil-over shocks that provide improved damping characteristics and a more compliant ride. The adjustable coil-overs allow for ride height customization, enabling owners to set the vehicle's stance according to their preference or to compensate for additional weight, such as a winch or bumper. 

The benefits of the Stage 1 system also include a more controlled and stable ride during high-speed off-roading, while still maintaining a level of comfort suitable for daily driving. With its straightforward bolt-on installation, this system is an excellent starting point for drivers looking to step into the world of performance suspension upgrades without overwhelming complexity.

Installation Process

Installing the ICON Stage 1 Suspension System on a Toyota 4Runner is designed to be a manageable task for individuals with mechanical experience. The process involves basic hand tools and can typically be completed within a day. The installation begins with safely lifting the vehicle and removing the stock suspension components. Following the included instruction manual, the new coil-over shocks are then mounted into place without the need for any permanent modifications to the vehicle. 

It's essential to ensure all bolts are torqued to the specified values to maintain safety and performance. After installation, an alignment is recommended to ensure proper vehicle handling and tire wear. For those who are less experienced or prefer professional assistance, a certified mechanic or an off-road specialist shop can perform the installation efficiently.

ICON Stage 2 Suspension System

Unique Additions of Stage 2

The ICON Stage 2 Suspension System builds upon the solid foundation laid by Stage 1, introducing unique additions that further refine the driving experience. This system includes a set of rear shocks with reservoirs that increase the system's oil capacity, thus providing better heat dissipation during extended off-road use. This leads to more consistent performance under strenuous conditions. Additionally, Stage 2 features upgraded vehicle-specific tuned shocks, optimizing the ride quality and handling characteristics. 

This stage also integrates billet aluminum upper control arms with ICON's patented Delta Joint, which combines the durability of a ball joint with the performance of a traditional uniball. The Delta Joint also allows for greater wheel travel and more precise control, making Stage 2 an excellent option for 4Runner owners who demand enhanced capability without sacrificing ride comfort.

Comparison with Stage 1

When comparing the ICON Stage 2 Suspension System to Stage 1, the key differences lie in the enhanced components and performance capabilities. While Stage 1 provides a substantial improvement over the stock suspension, Stage 2 takes it a step further by addressing the needs of more demanding off-road environments. The inclusion of rear reservoir shocks in Stage 2 offers better thermal management, which is crucial for maintaining consistent damping during prolonged off-road use. 

Additionally, the upgraded control arms with Delta Joints in Stage 2 promote increased wheel travel and more robust articulation, providing a noticeable improvement in off-road handling and obstacle negotiation. Overall, while Stage 1 is an excellent upgrade for everyday driving and light off-roading, Stage 2 is tailored for drivers who require a suspension system that can handle the rigors of more aggressive off-road adventures without compromising on-road comfort.

ICON Stage 3 Suspension System

Remarkable Attributes of Stage 3

The ICON Stage 3 Suspension System builds upon the capabilities of its predecessors with several remarkable attributes that cater to serious off-road enthusiasts. This advanced system includes multi-rate coil springs that provide a variable spring rate, enhancing vehicle stability and ride comfort across different terrains. The Stage 3 system also integrates remote reservoirs on both the front and rear shocks, which increase fluid capacity and heat dissipation, allowing for prolonged off-road performance without degradation. 

The shocks are further equipped with CDCV (Compression Damping Control Valve) technology, which gives drivers the ability to adjust the shock's compression damping to suit their specific needs or terrain conditions. This level of customization is what sets Stage 3 apart, offering unmatched tunability for optimal performance whether you're on a rocky trail or an asphalt road.

Why Upgrade to Stage 3?

Choosing to upgrade to the ICON Stage 3 Suspension System is a decision that caters to Toyota 4Runner owners who seek a high level of control and performance on varied terrains. The addition of CDCV technology offers the flexibility to fine-tune the suspension's response to different driving conditions, making it highly adaptable whether traversing technical trails or cruising on the highway. 

Stage 3 is also well-suited for vehicles carrying heavier loads, such as those with aftermarket bumpers, winches, or roof racks, as the enhanced spring rates and damping control help maintain ride quality and vehicle dynamics. For those who frequently venture into challenging off-road situations or who desire a highly customizable suspension system, the Stage 3 upgrade provides the necessary tools to tailor their driving experience meticulously. It's an investment in confidence and capability, ensuring your 4Runner is equipped to tackle the adventures ahead with ease.

ICON Stage 4 Suspension System

Stand-out Features of Stage 4

The ICON Stage 4 Suspension System is designed for those who push their Toyota 4Runner to the limits. It includes all the benefits of the previous stages while introducing additional stand-out features that cater to the most demanding off-road conditions. A key component of Stage 4 is the addition of billet aluminum rear lower trailing arms, which provide increased strength and durability over stock arms. 

These arms are paired with ICON's 2.5 Series piggyback reservoir shocks, both front and rear, which offer improved damping capabilities and a larger oil volume for sustained off-road performance. The Stage 4 system also incorporates adjustable track bars, allowing for precise alignment and handling even with significant suspension lifts. These features combine to create a more robust and responsive suspension system, ensuring that drivers have the utmost confidence in their vehicle's ability to conquer challenging terrains.

Comparisons Between Stage 2, 3, and 4

When differentiating between ICON's Stage 2, 3, and 4 suspension systems, it's important to consider the progressive enhancements each stage offers. Stage 2 introduces upgraded shocks with reservoirs and Delta Joints for improved articulation and durability. Moving to Stage 3, the inclusion of CDCV technology allows for customizable damping control, which is ideal for drivers who face a variety of terrain challenges and load demands. Stage 4 takes this a step further by adding billet aluminum trailing arms and adjustable track bars, which cater to those who may encounter the harshest off-road environments and require the highest level of performance. 

Each upgrade in stage represents a commitment to superior handling, increased durability, and the ability to fine-tune the vehicle's suspension to the driver's exact needs. The choice between stages should be informed by the driver's specific use-case scenarios and the desired balance between on-road comfort and off-road capability.

ICON Stage 5 Suspension System

Noteworthy Features of Stage 5

The pinnacle of ICON's suspension offerings for the Toyota 4Runner is the Stage 5 Suspension System, which incorporates the most advanced features for unparalleled performance.
