The **National LLC Part #710473** is a high-performance, precision-engineered **rear crankshaft seal** specifically designed for **Ram 2500 (and 3500) models manufactured between 2011 and 2019**, including both **V8 (5.7L, 6.4L, and 6.7L Cummins)** and **V6 (3.6L Pentastar)** configurations. This seal is crafted to deliver superior durability, leak resistance, and long-term reliability, making it an ideal replacement for the factory unit, which is prone to premature failure due to wear, oil contamination, or environmental exposure. Engineered from **high-quality elastomeric materials**, this seal features a **reinforced lip design** that ensures a tight, consistent seal against the crankshaft, preventing oil leaks that can lead to costly engine damage, reduced performance, or even catastrophic failure. The **precision-molded construction** minimizes friction while maintaining optimal pressure, reducing the risk of seal degradation over time especially critical for heavy-duty applications like towing, off-roading, or high-mileage operation. Additionally, the **compatible O-ring and gasket system** included with the seal ensures a secure fit within the rear main housing, further enhancing its longevity and preventing oil leaks at the seal interface. Whether addressing a **slow oil leak, a visibly worn seal, or a preventative maintenance upgrade**, this National seal provides a **direct-fit, no-compromise solution** that restores factory-like performance while offering enhanced protection against the stresses of daily driving, extreme temperatures, and demanding workloads. Built to meet or exceed OEM standards, this seal is a trusted choice for professional mechanics and DIY enthusiasts alike, ensuring a smooth, leak-free installation and extended engine life for your Ram 2500.
**Pros and Cons of buying a National 710473 Rear Crankshaft Seal for a 2011-2019 Ram 2500**
**Pros:**1. **Compatibility**: The National 710473 is specifically designed for the 2011-2019 Ram 2500, ensuring a proper fit and reducing the risk of installation issues. This seal is engineered to match the engine s specifications, including the crankshaft diameter and housing dimensions.
2. **Quality Materials**: National is a well-known brand in the aftermarket automotive parts industry, known for producing durable and reliable seals. The 710473 is likely made from high-quality rubber or synthetic materials that resist oil, heat, and wear, extending the life of the seal and reducing the likelihood of premature failure.
3. **Ease of Installation**: Since this is an OEM (Original Equipment Manufacturer) or high-quality aftermarket replacement, it should be straightforward to install, especially if you have some mechanical experience. The seal is designed to fit seamlessly into the crankshaft housing, minimizing the risk of leaks during installation.
4. **Warranty and Support**: National parts often come with warranties, providing some assurance against defects. Additionally, the brand has a reputation for customer support, which can be helpful if you encounter issues or need guidance during installation.
5. **Cost-Effective**: While the price may vary, this seal is likely more affordable than an OEM replacement from a dealership. It offers a balance between quality and cost, making it a practical choice for DIYers or those on a budget.

**Cons:**1. **Price Variability**: Depending on the retailer or whether you purchase online or in-store, the price of the National 710473 may fluctuate. Some sellers might mark up prices, especially if the seal is in high demand or if there are additional fees for shipping or handling.
2. **Potential Counterfeit Parts**: While less common with reputable brands like National, there is a risk of purchasing counterfeit or low-quality seals, particularly if buying from third-party sellers (e.g., eBay, Amazon, or lesser-known online marketplaces). Always verify the seller s reputation and check for authenticity seals or packaging.
3. **Installation Challenges**: While the seal itself is designed for easy installation, the process of removing the old seal, cleaning the housing, and ensuring the new seal is properly seated can be tricky. If you lack experience, you might damage the engine components or fail to install the seal correctly, leading to leaks or premature failure.
4. **Additional Costs**: Beyond the seal itself, you may need to purchase tools (e.g., seal puller, torque wrench, gasket scraper) or consumables (e.g., gasket maker, sealant) to complete the job properly. These extras can add to the overall cost and time required for the repair.
5. **Labor Time**: If you re not familiar with the procedure, the job could take longer than expected. Forcing the seal into place or struggling with stubborn components might lead to frustration or even damage to the engine bay.
6. **Limited Availability**: Depending on where you live, the National 710473 might not be readily available at local auto parts stores. You may need to order it online, which could result in longer wait times or shipping delays.
