---

### **Pros of the Apex Auto ABS1351 Crankshaft Seal**

1. **High-Quality Materials** The seal is made from durable rubber and reinforced with high-grade materials, designed to withstand the heat and pressure of a V8 engine. It is engineered to resist oil leakage and deformation over time.

2. **Direct Fitment** The ABS1351 is specifically designed for the **2014-2016 Silverado 1500** with the **5.3L (L86) and 6.2L (L83) engines**, ensuring an exact fit without modifications. This reduces the risk of installation errors.

3. **Reputable Brand** Apex Auto is a well-known manufacturer in the aftermarket automotive parts industry, with a strong reputation for reliability and performance. Their products are widely trusted by mechanics and DIY enthusiasts.

4. **Easy Installation** The seal is designed for straightforward replacement, though proper torque specifications must be followed to avoid damage. The packaging typically includes installation instructions, making it accessible for those with basic mechanical skills.

5. **Warranty Coverage** Apex Auto offers a warranty on their seals, providing some peace of mind against premature failure due to manufacturing defects.

6. **Cost-Effective Alternative to OEM** While not as cheap as generic seals, it is often more affordable than an **OEM (Original Equipment Manufacturer)** replacement, which can be expensive and may require an extended search for parts.

7. **Positive User Feedback** Many reviews from owners and mechanics highlight its durability and effectiveness in preventing oil leaks, especially when compared to cheaper alternatives.

### **Cons of the Apex Auto ABS1351 Crankshaft Seal**

1. **Limited Engine Compatibility** The ABS1351 is **only compatible with the 5.3L (L86) and 6.2L (L83) V8 engines** in the 2014-2016 Silverado 1500. If you have a different engine (e.g., 4.3L V6, 3.0L Duramax diesel, or older 5.3L pre-2014), this seal will not fit.

2. **Requires Professional Installation for Best Results** While the seal itself is easy to install, improper torque on the flywheel or flexplate can lead to damage or premature failure. Some users may need professional help to ensure a proper seal.

3. **Potential for Oil Leaks if Not Installed Correctly** If the seal is not seated properly or if the crankshaft is not cleaned thoroughly before installation, oil leaks can still occur. This is a common issue with crankshaft seals, regardless of brand.

4. **No Significant Performance Advantage Over OEM** Unlike some high-performance seals, the Apex ABS1351 does not offer any performance benefits beyond preventing leaks. It is a functional replacement, not an upgrade.

5. **Availability and Lead Times** While widely available, stock levels can vary depending on the retailer. Some users report occasional delays in receiving the part, especially during peak seasons.

6. **Price Point** While more affordable than OEM, it is still a premium aftermarket part. For budget-conscious buyers, there are cheaper alternatives (though with mixed reliability).

### **Conclusion**

The **Apex Auto ABS1351 crankshaft seal** is a **reliable, high-quality aftermarket option** for the **2014-2016 Chevrolet Silverado 1500** with the **5.3L (L86) or 6.2L (L83) V8 engine**. It offers a **direct fit, durable construction, and a strong reputation**, making it a **solid choice** for those looking to replace a leaking or worn-out seal. However, it is **not a universal solution** it is **engine-specific**, and proper installation is critical to its success.

If you are replacing a leaking crankshaft seal due to age or damage, the Apex ABS1351 is a **good balance between cost and quality**. For those on a tight budget, cheaper alternatives exist, but they may not last as long. If you want the **absolute best long-term solution**, an **OEM replacement** (if available) or a **high-end aftermarket brand** (such as **Fel-Pro or Sealed Power**) could be considered, though they come at a higher cost.
