The **Superlift Suspension 7138 RealTruck Block Kit** is a meticulously engineered, high-performance upgrade designed specifically for Toyota 4Runner and full-size pickup truck owners who demand both rugged capability and refined handling. Built to transform the stock suspension into a more robust, durable, and responsive system, this kit replaces the factory rear springs with a set of heavy-duty **7138 series leaf springs**, engineered to deliver a significant increase in ground clearance, improved articulation, and enhanced load-bearing capacity. Crafted from high-grade, heat-treated steel, these springs are precision-machined to maintain optimal strength while allowing for greater flexibility, ensuring they can handle the demands of off-road adventures, heavy payloads, and aggressive driving without compromising structural integrity. The RealTruck Block Kit is part of Superlift s **RealTruck** line, which is renowned for its focus on maintaining a balance between off-road prowess and on-road comfort, making it an ideal choice for those who require a suspension system that excels in both environments. Whether tackling rocky trails, deep mud, or steep inclines, these springs provide the necessary lift and stability to keep your vehicle planted and controlled, while also reducing body roll and improving overall vehicle dynamics. Additionally, the kit includes **high-quality shackles and bushings** that are designed to withstand the rigors of off-roading, reducing wear and extending the lifespan of your suspension components. Superlift s attention to detail is evident in the **pre-loaded spring design**, which ensures a smoother ride quality compared to aftermarket alternatives that may sacrifice comfort for lift alone. Perfect for enthusiasts who want to elevate their vehicle s performance without sacrificing reliability, the **7138 RealTruck Block Kit** is a standout choice for Toyota 4Runner and pickup truck owners looking to push the limits of their rig while maintaining a level of refinement that keeps daily driving enjoyable.
The SuperLift 7138 RealTruck Block Kit is a popular aftermarket suspension lift kit designed for Toyota 4Runners and other compatible trucks. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
**Pros:**1. **Height Increase and Improved Ground Clearance** The kit lifts the rear axle by approximately 3 inches (76mm), which is sufficient for many off-road applications, including over rocks, logs, and uneven terrain. This height is also beneficial for installing larger tires without rubbing.
2. **Durability and Quality Materials** SuperLift kits are known for using high-quality steel components, including heavy-duty springs and shocks. The materials are designed to withstand heavy loads and rough use, reducing the likelihood of premature failure.
3. **Compatibility with a Wide Range of Vehicles** The 7138 kit is designed for multiple Toyota models, including the 4Runner (2003 2013), Tacoma, and some older Hilux variants. This makes it a versatile choice if you re unsure about future vehicle modifications.
4. **Off-Road Performance Enhancements** The lift provides better articulation and approach/departure angles, which can improve off-road capability. The kit also includes upgraded shocks that offer better damping for rough terrain.
5. **Ease of Installation** While installation requires some mechanical skill, SuperLift kits are generally considered straightforward compared to more complex suspension setups. The kit includes detailed instructions, and many users report being able to complete the job in a weekend with basic tools.
6. **Positive Community Reputation** SuperLift has a strong reputation in the off-road community for reliability and customer support. Many users have had long-term success with their kits, and the company offers warranties and customer service to address issues.
7. **Compatibility with Other Modifications** The lift height is often paired well with larger tires (up to 35-inch sizes, depending on the setup) and other off-road components like skid plates, diff locks, and locking differentials.
---
**Cons:**1. **Limited Lift Height for Some Applications** At only 3 inches, this kit may feel underwhelming if you re looking for a significant lift for extreme off-roading or heavy-duty applications. Some users prefer 4 6 inch lifts for better articulation and tire clearance.
2. **Potential for Wheel Bounce** A 3-inch lift can sometimes lead to wheel bounce on rough terrain, especially if the shocks are not properly tuned or if the vehicle is heavily loaded. Upgrading to aftermarket shocks (e.g., Fox or Bilstein) may be necessary to mitigate this.
3. **Sway Bar Removal Required** The kit typically requires the removal of the stock sway bar, which can affect handling on pavement. This trade-off is often acceptable for off-road use but may be noticeable on highways or in tight corners.
4. **Cost** While not excessively expensive for a lift kit, the 7138 kit can be on the pricier end compared to some competitors. Additional costs may arise from purchasing new tires, wheels, or other components to fully optimize the setup.
5. **Potential for Rubbing on Stock Components** Depending on the vehicle s stock setup (e.g., close-ratio differentials, stock exhaust), some users may experience rubbing issues that require additional modifications like exhaust heat shields or diff relocation.
6. **Installation Challenges for Beginners** While not overly complex, installing a lift kit requires attention to detail, especially when aligning the new springs and shocks. Mistakes in installation (e.g., incorrect spring perch placement) can lead to handling issues or premature wear.
7. **Limited Customization** The kit is a pre-engineered solution, so you re limited to the lift height and components provided. If you want to adjust the ride height further or customize the suspension, you may need to supplement with additional parts.

**Conclusion:**The SuperLift 7138 RealTruck Block Kit is a solid choice for Toyota 4Runners and compatible trucks seeking a moderate lift for improved off-road capability without overcomplicating the setup. It offers a good balance of durability, ease of installation, and compatibility with other modifications. However, it may not be ideal for those looking for a more aggressive lift or extreme off-road performance. The kit s strengths lie in its reliability, quality materials, and proven track record in the off-road community, making it a practical option for both beginners and experienced modders.

**Recommendation:**If you re looking for a **practical, mid-range lift** that enhances off-road capability without requiring extensive modifications, the SuperLift 7138 kit is an excellent choice. It s particularly well-suited for:
- Drivers who prioritize durability and ease of installation.
- Those who plan to run larger tires (up to 35-inch sizes) without rubbing.
- Users who want a lift that improves articulation but doesn t sacrifice too much on-road comfort.
However, if you re aiming for **extreme off-road use** (e.g., rock crawling, deep mud, or heavy-duty towing), consider pairing this lift with aftermarket shocks or exploring higher-lift kits (e.g., 4 6 inches). Additionally, if you re new to suspension modifications, be prepared to invest time in proper installation and potentially supplement the kit with other components (e.g., sway bar disconnects, exhaust heat shields) to avoid rubbing issues.
For most casual to intermediate off-road enthusiasts, the SuperLift 7138 kit delivers a reliable and effective lift that justifies its cost. Always pair it with a thorough understanding of your vehicle s needs and consider consulting with experienced modders or forums (e.g., 4Runner.net) before committing.
