Whether restoring a daily driver to its original glory or upgrading an off-road rig for better control, the Dorman MAS Select IS318 steering kit provides a **direct, no-nonsense steering experience** that bridges the gap between classic charm and modern performance.

Beyond its functional excellence, the Dorman MAS Select IS318 steering kit is built with **installation convenience** in mind, featuring **pre-lubricated components** to simplify assembly and reduce the risk of premature wear during break-in.

The kit also incorporates **high-quality bearings and seals**, ensuring minimal maintenance requirements and extended service life, making it an ideal choice for enthusiasts who prioritize both performance and reliability. For those seeking a **drop-in replacement** that doesn t require extensive modifications, the Dorman MAS Select IS318 kit is engineered to fit seamlessly with existing steering linkages, tie rods, and rack-and-pinion or recirculating ball systems, offering a **plug-and-play upgrade** that restores confidence in every turn. Whether tackling tight corners on a backroad or maintaining stability during high-speed cruising, this steering kit ensures that the driver s intent is translated into precise, immediate action making it an indispensable upgrade for anyone serious about enhancing their vehicle s handling dynamics.

### **Pros and Cons of Buying a Dorman MAS Select Chassis IS318 Steering Rack**

The Dorman MAS Select Chassis IS318 steering rack is a popular aftermarket replacement for various GM vehicles, including the GMC Sierra, Chevrolet Silverado, and GMC Yukon. Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros**

1. **High-Quality Construction**

The IS318 rack is built with durable materials, including hardened steel components and precision-machined parts. This ensures longevity and resistance to wear, especially in heavy-duty applications.

2. **Compatibility with Multiple Vehicles**

This steering rack is designed to fit a wide range of GM trucks and SUVs from the late 1990s through the early 2010s. This makes it a versatile choice for restomodders and DIY enthusiasts working on classic or modernized vehicles.

3. **Improved Steering Feel and Precision**

Many users report a noticeable improvement in steering responsiveness compared to stock or worn-out racks. The rack s design reduces play and provides a more direct connection between the steering wheel and wheels, enhancing driver engagement.

4. **Easy Installation**

Dorman provides detailed installation instructions, and the rack is designed to be a drop-in replacement for the original equipment (OEM) unit. Most installations require basic tools and can be completed in a few hours, depending on the vehicle s complexity.

5. **Warranty Coverage**

Dorman offers a limited warranty (typically 12 months or 12,000 miles, depending on the model), which provides peace of mind against manufacturing defects. This is more substantial than some aftermarket alternatives that offer minimal or no warranty.

6. **Cost-Effective Alternative to OEM**

Purchasing a new Dorman rack is often cheaper than buying an OEM replacement from a dealership, especially if the vehicle is out of production. It also avoids the potential for inflated prices associated with rare or discontinued parts.

7. **Compatibility with Upgrades**

The IS318 rack can be paired with other Dorman or aftermarket steering components, such as tie rods, ball joints, and steering stabilizers, to further enhance performance and durability.

8. **Reduced Leakage and Improved Sealing**

The rack features improved seals and mounting points, which can help prevent fluid leaks a common issue with older steering racks. This reduces the risk of hydraulic fluid loss and potential damage to other steering components.

9. **Positive Community Feedback**

The Dorman MAS Select line has garnered a strong reputation among truck and SUV enthusiasts for reliability and performance. Online forums and reviews frequently highlight its durability and ease of use.

10. **Support for Restomod and Custom Builds**

For those restoring or customizing older vehicles, the IS318 rack can help modernize the steering system without sacrificing performance. It s a popular choice for builds that blend classic aesthetics with modern functionality.

---

### **Cons**

1. **Limited Customization**

Unlike some high-end aftermarket racks, the Dorman IS318 is not highly customizable. It is a standard replacement part with fixed geometry and no adjustable settings for steering ratio or offset. This may be a drawback for those seeking specialized performance tuning.

2. **Potential Fitment Issues**

While the rack is designed for a broad range of vehicles, some builds particularly those involving extensive modifications, lifted suspensions, or aftermarket frames may require additional adjustments or spacers. Poor fitment can lead to binding or improper alignment.

3. **No Direct Drive Option**

The IS318 is a hydraulic rack, meaning it relies on power steering fluid and a pump. It does not offer a direct-drive (rack-and-pinion) option, which some enthusiasts prefer for off-road or minimalist builds where power steering is unnecessary.

4. **Dependence on Power Steering System**

If the vehicle s power steering pump or fluid reservoir is failing, the rack s performance will be compromised. This requires maintaining the entire power steering system, not just the rack itself.

5. **Mixed Reviews on Durability in Extreme Conditions**

While the rack is robust, some users operating in harsh off-road or heavy-duty conditions report premature wear, particularly in the tie rod ends or mounting bushings. This may require additional reinforcement or upgrades.

6. **Installation Challenges for Non-Mechanics**

While the installation is generally straightforward, those without mechanical experience may struggle with tasks such as aligning the rack, torquing bolts to specification, or handling hydraulic bleeding. Improper installation can lead to steering issues or premature failure.

7. **Price Point Relative to Premium Brands**

While Dorman offers good value, high-end aftermarket brands (e.g., Moog, Trac-Bec, or custom racks) may provide additional features like adjustable geometry, improved materials, or extended warranties. For serious off-road or performance builds, these premium options might be worth the investment.

8. **Limited Availability of Spare Parts**

If the rack fails, finding replacement parts or a full replacement may be easier with Dorman due to its widespread availability. However, compared to OEM parts, aftermarket support for Dorman components may not be as extensive in some regions.

9. **Potential for Hydraulic Noise**

Some users report hydraulic whining or pumping noises, particularly in older vehicles with worn-out power steering systems. This can be mitigated by ensuring the power steering fluid is clean and the system is properly bled.

10. **Not Ideal for Heavy Lifting or Extreme Modifications**

While the IS318 is sturdy, it is not designed for extreme modifications such as heavy lifting (e.g., 4-inch lifts or more) or aggressive off-road use without additional reinforcement. In such cases, a more robust rack (e.g., a Trac-Bec or custom-built unit) may be necessary.

---

### **Ending Conclusion**

The Dorman MAS Select Chassis IS318 steering rack is an excellent choice for most GM truck and SUV owners seeking a reliable, cost-effective replacement for their original steering system. It offers a balance of quality, compatibility, and ease of installation, making it suitable for both everyday drivers and enthusiasts working on restomod projects. The rack s durability and warranty coverage further enhance its appeal, particularly for those who prioritize value without sacrificing performance.

However, it is not without limitations. Those planning extensive modifications, off-road adventures, or custom builds may need to supplement the rack with additional components or consider premium alternatives. Additionally, users should ensure proper installation and maintenance to maximize longevity and avoid potential issues.

For the average driver or restomoder looking to upgrade their steering system, the Dorman IS318 rack is a highly recommended option. It strikes a strong balance between affordability, performance, and reliability, making it a standout product in the aftermarket steering rack market.
