Review BRIAN CROWER Connecting Rods Lightweight .935 Inch 1.890 K24 Stroker 5.985

The **Brian Crower BC6059 connecting rods** are a meticulously engineered, high-performance solution designed specifically for the **Mercedes-Benz M117 935 1.890cc K24 stroker engine**, pushing displacement to an impressive **5.985 cubic inches** while maintaining the integrity and reliability expected from a legendary racing platform. Crafted from **forged 4340 steel**, these rods embody precision and durability, featuring a **fully counterweighted design** to balance the increased reciprocating mass of the stroker crankshaft, reducing vibration and enhancing smoothness under extreme power outputs. The **6059 designation** indicates a **5.985-inch bolt-to-bolt length**, optimized for the K24 s compact block while accommodating oversized pistons and a longer stroke ideal for those seeking a balance between high-revving performance and low-end torque. Each rod is **shot-peened** for surface hardening, eliminating stress risers and ensuring longevity even under the most demanding conditions, such as high-RPM drag racing or track-day applications. The **split-pin retained wrist pins** are precision-machined to minimize friction, while the **fully machined rod caps** feature **locking tabs** for secure assembly, preventing any potential for loosening under extreme G-forces. Whether paired with a **stroker kit, forged pistons, or a high-flow cylinder head**, these rods deliver the structural strength and rigidity necessary to handle the stresses of aggressive tuning without compromising reliability. Perfect for enthusiasts looking to preserve the **935 s racing pedigree** while pushing its limits with modern performance upgrades, the BC6059 rods are a testament to Brian Crower s commitment to craftsmanship and the demands of high-performance engineering.

### Pros and Cons of Buying Brian Crower BC6059 Connecting Rods for a Porsche 935/934 1.890 K24 Stroker (5.985" Stroke)

1. **High-Quality Materials** Brian Crower rods are forged from premium aircraft-grade aluminum alloy (7075-T6), ensuring strength and durability. The use of high-quality materials reduces the risk of failure under extreme stress.

2. **Precision Engineering** BC rods are machined to tight tolerances, which improves engine balance and reduces vibration. This is critical for high-performance applications like a stroker engine, where even minor imbalances can lead to premature wear or failure.

3. **Proven Track Record** Brian Crower has been a trusted name in engine building for decades, with a reputation for reliability in both street and racing applications. Many high-performance engines, including those in classic Porsche 935/934 builds, have used BC rods successfully.

4. **Compatibility with Stroker Applications** The BC6059 rods are designed for longer strokes (5.985" in this case), which means they are optimized for the increased stress placed on connecting rods in a stroker setup. They are also compatible with the 935/934 s crankshaft and piston configurations when properly matched.

5. **Lightweight Yet Strong** The rods are lighter than steel alternatives, reducing reciprocating mass, which can improve engine responsiveness and reduce wear on other components like the crankshaft and bearings.

6. **Warranty and Support** Brian Crower offers warranties on their rods, and their customer service is well-regarded in the engine-building community. This provides peace of mind for buyers investing in high-performance parts.

7. **Custom Fit for Porsche Engines** The rods are specifically designed to fit the 935/934 s engine bay and bolt patterns, reducing the need for extensive modifications or custom fabrication.

8. **Racing Heritage** BC rods have been used in professional racing, including drag racing and endurance events, which speaks to their ability to handle extreme power outputs without failing.

1. **Cost** High-quality aluminum rods are more expensive than steel rods. For a stroker build, the cost can add up significantly, especially when factoring in additional components like pistons, bearings, and machining costs.

2. **Maintenance and Inspection Requirements** Aluminum rods require careful inspection for cracks or fatigue, especially in high-RPM or high-stress applications. Unlike steel, aluminum is more prone to stress corrosion cracking if not properly maintained (e.g., proper lubrication, cooling, and regular checks).

3. **Limited Availability of Aftermarket Support** While BC rods are well-supported, some specialized machining or balancing may require a trusted engine builder. Not all shops may have experience with aluminum rods, which could complicate installation or troubleshooting.

4. **Potential for Misuse** If the engine is not properly built around the rods (e.g., incorrect piston-to-rod clearance, improper bearing selection, or inadequate cooling), the rods could fail prematurely. This risk is mitigated by working with an experienced engine builder.

5. **Resale Value** While BC rods are durable, they are not as universally recognized as some other brands (e.g., Eagle or Scat) in all markets. This could slightly impact resale value if the engine is ever sold or rebuilt.

6. **Installation Complexity** Installing aluminum rods requires precision assembly, including proper gapping of bearings, checking for rod-to-crankshaft clearance, and ensuring the pistons are correctly matched. Mistakes in assembly can lead to catastrophic failure.

7. **Not Ideal for Extreme Overbuilding** While BC rods are strong, they are not designed for the most extreme power levels (e.g., 1,000 HP without additional reinforcement). For such applications, other rod options (e.g., forged steel or titanium) might be considered.

Brian Crower BC6059 rods are an excellent choice for a Porsche 935/934 1.890 K24 stroker build, especially if the goal is a balance of performance, reliability, and lightweight construction. Their precision engineering, high-quality materials, and proven track record make them a trusted option for high-performance applications. However, they are not without drawbacks, particularly their cost and the need for meticulous installation and maintenance.

For most enthusiasts building a stroker engine for track or high-performance street use, the BC6059 rods are a strong recommendation provided the engine is properly built and maintained. If budget is a concern, steel rods (e.g., Eagle or Scat) could be considered, but they would add weight and may not offer the same level of performance benefits.

If you are committed to a stroker build for your 935/934 and prioritize lightweight, high-performance components with a strong reputation, the **Brian Crower BC6059 rods are an outstanding choice**. Pair them with:

- High-quality forged pistons (e.g., JE or Manley) matched to the rods.

- Proper bearing selection (e.g., Clevite or ISCO) for the power levels you intend to target.

- A trusted engine builder with experience in aluminum rod assemblies.

- Regular inspections and maintenance to monitor for stress or wear.

Avoid cutting corners on other critical components (e.g., crankshaft, oil system, or cooling) to ensure the rods perform as intended. If you are unsure about any aspect of the build, consult an expert before finalizing the purchase.
