The **Clevite SH2138 CLE Indiv Camshaft Bearing** is a precision-engineered, high-performance bearing designed to deliver exceptional durability, reliability, and smooth operation in demanding high-performance and racing applications. Manufactured by Clevite, a trusted name in automotive and industrial bearings, this individual camshaft bearing is crafted from a proprietary **lead-indium alloy** that offers superior resistance to wear, scuffing, and fatigue even under extreme loads and high-speed conditions. The SH2138 CLE features a **smooth, polished surface finish** and a **tight tolerance** to ensure minimal friction and optimal lubrication retention, which is critical for maintaining consistent camshaft operation in aggressive engine setups. These bearings are specifically engineered for **individual valve lifter (IVO) or roller lifter applications**, where precision and longevity are paramount, making them an ideal choice for high-revving, forced-induction, or nitrous-enhanced engines. Their **self-lubricating properties** and resistance to galling make them well-suited for both street and track use, where reliability under thermal and mechanical stress is non-negotiable. Whether installed in a high-performance V8, turbocharged engine, or a supercharged application, the SH2138 CLE bearings provide the structural integrity and performance consistency required to push an engine to its limits without compromising on longevity. Built to meet or exceed OEM specifications while offering enhanced durability, these bearings are a staple in aftermarket engine builds where performance and reliability are inseparable.
**Pros and Cons of Buying Clevite SH2138 CLE Indiv Camshaft Bearings**
**Pros:**1. **High Quality and Durability:** Clevite bearings are known for their robust construction and reliability, often outperforming lower-cost alternatives in terms of longevity and performance. The SH2138 model is designed for high-stress applications, such as performance engines or heavy-duty use, ensuring consistent operation under demanding conditions.
2. **Precision Engineering:** These bearings are manufactured with tight tolerances, which helps minimize friction and wear on the camshaft. This precision contributes to smoother engine operation, reduced noise, and improved efficiency.
3. **Compatibility:** The SH2138 CLE bearings are designed specifically for certain engine applications (e.g., GM LS-series engines or similar high-performance setups). Their individual (CLE) design allows for better heat dissipation and reduced risk of oil starvation compared to traditional full-width bearings.
4. **Widely Available:** Clevite is a well-established brand with a broad distribution network, making it easier to find replacements or additional parts if needed. They are also commonly recommended by mechanics and tuners for performance builds.
5. **Performance Benefits:** For engines running at higher RPMs or under heavy loads, these bearings can help maintain stability and reduce the risk of catastrophic failure, such as a seized camshaft.
6. **Warranty and Support:** Clevite products often come with manufacturer warranties, and the brand has a reputation for standing behind its parts. This can provide peace of mind, especially in critical applications.

**Cons:**1. **Cost:** Clevite bearings, particularly high-performance or individually designed ones like the SH2138 CLE, are more expensive than generic or aftermarket alternatives. For budget-conscious buyers, this may be a significant drawback, especially if the engine isn t heavily modified or stressed.
2. **Installation Complexity:** Replacing camshaft bearings often requires disassembling the engine or cylinder head, which can be labor-intensive. If the buyer lacks mechanical experience, professional installation may be necessary, adding to the overall cost.
3. **Potential Overkill for Mild Applications:** If the engine is stock or only lightly modified, the SH2138 CLE bearings may offer little advantage over standard bearings. In such cases, the higher cost may not be justified unless the engine is running at elevated temperatures or RPMs.
4. **Oil Requirements:** High-performance bearings like these often perform best with high-quality oil that meets or exceeds the manufacturer s specifications. Using subpar oil can negate some of the benefits of the bearings and may even void warranties.
5. **Limited Customization:** Unlike some aftermarket options, Clevite bearings are not typically available in a wide range of materials or coatings (e.g., ceramic or specialized plating). This limits options for those seeking niche performance enhancements.
6. **Risk of Contamination:** If the engine is rebuilt or the bearings are installed improperly, contaminants like metal shavings or debris can damage the bearings during operation. This risk applies to any high-quality bearing but is particularly critical with precision components.

**Conclusion:**The Clevite SH2138 CLE individual camshaft bearings are an excellent choice for high-performance, heavily stressed, or modified engines where reliability and durability are paramount. Their precision engineering, compatibility with demanding applications, and reputation for quality make them a strong option for serious builders or those seeking to extend the life of their engine. However, the higher cost and installation complexity may not be worth it for stock or lightly modified engines where standard bearings would suffice. Additionally, the benefits are maximized only when paired with proper installation techniques and high-quality lubricants.
**Recommendation:** Purchase the Clevite SH2138 CLE bearings if:- You are rebuilding or modifying an engine for high-performance use (e.g., forced induction, high RPMs, or heavy-duty applications).
- Your engine runs at elevated temperatures or stresses that warrant premium components.
- You have access to professional installation or mechanical expertise to ensure proper fitting and oil management.
Avoid or reconsider if:- Your engine is stock or only mildly modified, and you are working within a tight budget.
- You lack the experience or tools to install the bearings correctly, as improper installation can lead to premature failure.
- You are not using high-quality oil or maintaining the engine according to manufacturer guidelines.
For most performance builds, the investment in Clevite bearings is justified by their ability to enhance reliability and performance. However, always weigh the cost against the specific needs of your engine and application.
