Review DIY SOLUTIONS Gmc S15 Pitman Arm fits 4WD 1985–1990

The **GMC S15 4WD Pitman Arm (Part #37112BTBW)** is a meticulously engineered, high-performance replacement component designed specifically for the iconic **1985 through 1990 GMC S15** series, including the **1986, 1987, 1988, and 1989 models** equipped with four-wheel-drive systems. This robust, heavy-duty pitman arm serves as a critical linkage in the S15 s transfer case and axle assembly, transmitting power from the transfer case to the rear axle while maintaining precise alignment and structural integrity under demanding off-road and heavy-duty conditions. Crafted from **durable, heat-treated steel**, this arm is built to withstand the relentless stresses of rugged terrain, frequent towing, and prolonged use, ensuring reliable performance even in the most extreme environments. Its **smooth, machined surfaces** and **precision-engineered mounting points** guarantee minimal wear and optimal articulation, reducing the risk of premature failure and extending the lifespan of the entire drivetrain. The **universal fitment** for the specified model years makes it an essential upgrade for both restoration projects and daily-drive applications, offering a seamless replacement for the original equipment manufacturer (OEM) component without compromising on strength or functionality. Whether you re tackling rocky trails, deep mud, or icy roads, this pitman arm delivers the durability and responsiveness needed to keep your S15 s 4WD system operating at peak efficiency, ensuring a smoother, more reliable driving experience for years to come.

### Pros and Cons of buying a **37112BTBW Pitman Arm for 1985 1990 GMC S15 (4WD, 1986 1987 1988 1989 Models)**

#### **Pros:**

1. **Direct Fitment** The **37112BTBW** is a direct replacement for the stock pitman arm on your GMC S15, ensuring compatibility without modifications. It s designed specifically for the 1985 1990 models, including the 4WD variants from 1986 onward.

2. **Durability** High-quality materials (likely steel or heavy-duty alloy) are used in aftermarket pitman arms, reducing the risk of premature wear or failure compared to a worn-out OEM part. This can extend the lifespan of your steering components.

3. **Reliability** A failing pitman arm can cause excessive play in the steering, leading to poor handling or even sudden loss of control. Replacing it with a new one eliminates these risks, improving steering responsiveness and safety.

4. **Preventative Maintenance** If your current pitman arm is worn or cracked, replacing it proactively avoids costly damage to other steering components (e.g., tie rods, steering box, or frame).

5. **Ease of Installation** The part is designed for straightforward installation, often requiring only basic tools. Many owners and mechanics report that it bolts on in under an hour with no special skills needed.

6. **Cost-Effective** Compared to the potential cost of repairing steering damage caused by a failing pitman arm, buying this part is a budget-friendly solution. Prices are reasonable for a direct replacement.

7. **Compatibility with Upgrades** If you re planning to modify your S15 (e.g., lift kits, off-road suspension), a new pitman arm ensures the steering system remains aligned and functional with the changes.

#### **Cons:**

1. **Potential Quality Variations** While many aftermarket parts are reliable, lower-quality replicas may develop cracks or wear out faster than expected. Always check reviews or buy from reputable brands (e.g., Moroso, Eibach, or local trusted suppliers).

2. **Installation Challenges** If the pitman arm is rusted or seized to the steering linkage, removal can be difficult. You may need penetrating oil, heat guns, or a press to free it. Improper installation (e.g., misalignment) could lead to premature wear.

3. **Limited Customization** Unlike some steering components, pitman arms are not adjustable or interchangeable with other models. You re locked into the stock dimensions unless you modify the steering geometry, which isn t recommended for daily driving.

4. **Hidden Damage Risk** If the steering box or frame is already damaged (e.g., from a prior accident), replacing just the pitman arm won t fix underlying issues. A full steering inspection is advisable before purchase.

5. **Misalignment Issues** If the new pitman arm isn t installed with the correct alignment (e.g., not matching the tie rod angles), it can cause uneven tire wear or a "wandering" steering wheel. This may require professional alignment afterward.

6. **Availability of Genuine Parts** While aftermarket parts are widely available, finding a **genuine OEM pitman arm** (if preferred) may require sourcing from junkyards or online marketplaces, which could be less convenient.

7. **Labor Costs** If you re not comfortable with DIY repairs, labor costs at a shop can add up, especially if additional work (e.g., steering box service) is needed.

### **Conclusion**

The **37112BTBW pitman arm** is a **solid, cost-effective replacement** for your 1985 1990 GMC S15, particularly if your current arm is worn or failing. It offers **direct fitment, durability, and safety benefits**, making it a practical choice for maintenance or restoration. However, **quality control, installation ease, and potential hidden issues** (like steering misalignment) are factors to consider.

**Recommendation:**

- **Buy it** if your pitman arm shows signs of wear (cracks, excessive play, or rust) and you re confident in your ability to install it correctly. Opt for a **reputable brand** to avoid poor-quality replicas.

- **Inspect the steering system** before purchasing check for damaged tie rods, worn bushings, or steering box leaks. If other components are failing, address them simultaneously.

- **Consider professional installation** if you re unsure about alignment or if the arm is stubborn to remove.

- **Pair with a steering box flush** (if needed) to ensure smooth operation after replacement.

- **Avoid cheap no-name brands** prioritize parts with good reviews or warranties.

**Final Verdict:** This is a **worthwhile upgrade** for most S15 owners, balancing cost, reliability, and ease of use. Just ensure proper installation and maintenance to maximize its lifespan.
