FAQs

Can I reuse these bolts after removing them?

No. These bolts are designed for single-use and undergo stretching during the torquing process; they must be replaced every time they are removed.

What does the 12.9 strength rating mean?

The 12.9 rating refers to the mechanical properties of the bolt, indicating high tensile strength suitable for high-stress industrial and automotive applications.

How do I know if this fits my vehicle?

You should check your vehicle's service manual or use the original equipment (OE) part numbers to cross-reference compatibility with the FEBI BILSTEIN 02126.

Is the phosphated surface coating permanent?

The coating is designed to protect the bolt from corrosion during storage and early engine operation; it does not require removal before installation.

Does this bolt come with a nut?

No, this listing is for the connecting rod bolt only. Ensure you have all necessary hardware required by your engine's specific rebuild kit.

Troubleshooting

Bolt does not thread into the connecting rod smoothly

Stop immediately, remove the bolt, and check for damaged threads in the connecting rod housing or debris in the hole.

Torque wrench does not click at the expected specification

Verify that your torque wrench is calibrated and ensure you are using the correct torque-to-yield procedure, which often involves a set torque plus an additional degree of rotation.

Pros and Cons

Pros

  • Meets or exceeds original equipment manufacturing standards
  • High-grade 12.9 material for maximum tensile strength
  • Corrosion-resistant phosphated coating
  • Precise dimensions for easy installation

Cons

  • Requires specific torque-to-yield knowledge for proper installation
  • Not compatible with all engine types; verification required
  • Single-use component; cannot be reused after removal

Setup, Compatibility & Care

Before installation, ensure the engine block and connecting rod surfaces are clean and free of debris. It is crucial to verify vehicle compatibility using your vehicle's specific OE part numbers, as slight variations in engine models can impact fitment.

  1. Always clean the internal threads of the connecting rod housing before insertion.
  2. Lightly lubricate the threads and the underside of the bolt head with clean engine oil or assembly lubricant as specified by the manufacturer.
  3. Follow the manufacturer's specified torque sequence and angle-tightening procedure (torque-to-yield) strictly.
  4. Never reuse these bolts after they have been tightened to their yield point during a previous engine assembly.
