IFS, with its complex setup, can struggle with extreme articulation and the constant pounding of rocks and obstacles. This is where the solid axle swap (SAS) comes into play, offering a significant improvement in off-road capability, durability, and the sheer thrill of conquering the toughest trails.
This article dives deep into the world of the 2nd gen Tacoma SAS kit, exploring what it is, why it’s beneficial, how to choose the right one, and what you need to consider before embarking on this exciting upgrade. We’ll unravel the complexities, demystify the components, and empower you with the knowledge to make an informed decision about transforming your Tacoma into a true off-road beast. Get ready to push your Tacoma’s boundaries and explore the uncharted territories that await.
What Exactly is a 2nd Gen Tacoma SAS Kit?
At its core, a solid axle swap involves replacing your Tacoma’s factory IFS with a solid front axle, a more robust and capable setup for off-roading. The solid axle, unlike the independently moving wheels of the IFS, is a single, rigid unit that houses the differential and axle shafts. This fundamental change opens up a world of possibilities for off-road performance.
But what components make up a typical 2nd gen Tacoma SAS kit? While the specifics can vary depending on the manufacturer and the desired level of performance, a comprehensive kit generally includes the following key parts:
Axle Housing
This is the backbone of the solid axle, a strong and durable housing that protects the differential and axles. Common choices for the 2nd gen Tacoma SAS kit include axles from Dana (e.g., Dana 44, Dana 60) and Ford (e.g., Ford 9-inch).
Axle Shafts
These connect the differential to the wheels, transmitting power and allowing for rotation.
Differential
This allows the wheels to rotate at different speeds, crucial for turning.
Coil Springs or Leaf Springs
The suspension’s primary component for supporting the vehicle and absorbing impacts.
Shocks
Coilover shocks or traditional shocks work in tandem with the springs to control suspension movement and dampen bumps.
Control Arms/Links (for coil spring setups)
These connect the axle to the frame, controlling axle movement.
Track Bar/Panhard Bar
These bars help to center and control the lateral movement of the axle.
Steering Components
These include the steering arm, tie rod, and drag link, connecting the steering box to the axle.
Brake Lines
These are modified or replaced to accommodate the new axle setup.
U-Joints and Driveshafts
These must be custom-made or adapted to connect the transfer case to the new front axle.
Bump Stops
Limits the suspension compression and prevents damage.
Keep in mind that a complete kit might not include everything. Some kits are designed to be more “bolt-on,” including more pre-fabricated parts, while others may require more fabrication and custom work. This affects the price.
The Incredible Benefits of a 2nd Gen Tacoma SAS Kit
Choosing a 2nd gen Tacoma SAS kit is a significant undertaking, but the rewards are worth it. The benefits extend far beyond simply improving off-road performance.
Enhanced Off-Road Performance
With a solid axle, you’ll experience a dramatic improvement in:
Ground Clearance
Solid axles generally sit lower than IFS, but also offer a stronger, more rigid structure to deflect rocks. More importantly, SAS allows for a higher ride height.
Articulation
This is the ability of the wheels to move independently. SAS offers significantly greater articulation, allowing your wheels to stay on the ground longer, providing increased traction and stability on uneven terrain.
Durability
The components of a solid axle are, in general, more robust than the IFS components. They are built to withstand the impact and abuse of serious off-roading.
Reliability
Simplified design means fewer moving parts. SAS is easier to repair in the field.
Handling
Better handling on any type of surface when climbing, descending, or maneuvering around obstacles.
Beyond these performance gains, a 2nd gen Tacoma SAS kit also offers these advantages:
Increased Strength
Solid axles are inherently stronger than IFS setups. They can handle more abuse, making them ideal for rock crawling, extreme trails, and carrying heavier loads. This means your Tacoma can handle more challenging terrain without fear of breaking components.
Tire Size Upgrades
SAS allows for much larger tires. Large tires, and their associated lift, contribute significantly to the overall off-road capability.
Customization
A 2nd gen Tacoma SAS kit offers a high degree of customization. You can choose the specific axle type, gear ratios, and suspension setup that best suits your off-roading style and preferences. This level of personalization is simply not possible with the stock IFS. You can fine-tune every aspect of your suspension to maximize performance.
Resale Value
A well-executed solid axle swap can significantly increase the resale value of your Tacoma, attracting buyers seeking a capable off-road vehicle.
