Maintain engine reliability during rebuild work with this OE
Connecting Rod Bolt. The connecting rod bolt is a critical internal
engine fastener used to secure the connecting rod cap to the connecting rod
body around the crankshaft journal.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 914 (1970-1976)

Although small, this component is subjected to extreme loads every time the engine runs. It must maintain precise clamping force under high RPM, combustion pressure, heat and vibration. For this reason, connecting rod bolts should be treated as essential engine rebuild hardware and replaced whenever the connecting rods are removed or serviced.
What Does a Connecting Rod Bolt Do?
The connecting rod bolt clamps the rod cap securely to the connecting rod.
Its main functions include:
- Securing the connecting rod cap
- Maintaining bearing alignment
- Supporting correct crankshaft rotation
- Preserving bearing crush
- Withstanding high engine loads
- Helping prevent internal engine failure
Correct clamping force is vital for engine durability and safe operation.
Why Do Connecting Rod Bolts Fail?
Connecting rod bolts operate under severe stress and can weaken over time.
Common causes of failure include:
- Metal fatigue
- Overstretching during previous installation
- Incorrect torque procedures
- High RPM engine use
- Heat cycling
- Thread damage
- Reuse during engine rebuilds
- General age and wear
Many connecting rod bolts are considered single-use components and should not be reused once removed.
When Should They Be Replaced?
Replacement is strongly recommended when:
- Rebuilding the engine
- Removing connecting rods
- Replacing big end bearings
- Servicing the crankshaft
- Building a performance engine
- Inspecting high-mileage engines
- Previous torque history is unknown
Replacing rod bolts during rebuild work is inexpensive protection against serious engine damage.
Why Replacement Matters
A failed connecting rod bolt can cause catastrophic engine failure.
Benefits of replacement include:
- Correct clamping force
- Improved engine reliability
- Protection of crankshaft and bearings
- Reduced risk of rod cap movement
- Professional rebuild standards
- Long-term engine durability
- Greater peace of mind

CP-Carrillo connecting rods are fully machined from a proprietary 4330m alloy forging for strength and durability. Rods are available with 2 types of bolts: The standard WMC-H6 bolt with a UTS of 220ksi and our upgraded CARR-S6 bolt with a UTS of 285ksi. The CARR upgraded bolt is a good choice if planning on revving the engine higher than 8500rpm.
All our bolts are manufactured with asymmetrical threads, each thread has a slightly different design than the previous giving the bolts an evenly distributed thread engagement. This helps increasing the clamp load and fatigue life of the fasteners
