Precision machined to maintain original journal dimensions, this crankshaft ensures proper bearing clearance, smooth rotation and reliable power delivery. When rebuilding a high-performance flat-six engine, choosing the correct standard size crankshaft is essential to restoring the engine’s structural integrity and achieving long-term durability.

Engineered to meet the performance characteristics of the original design, this crankshaft is ideal for restorations, performance rebuilds and repairs requiring uncompromising accuracy and balance.

What the Engine Crankshaft Does

This crankshaft delivers several vital engine functions, including:

  • Converting piston motion into smooth rotational force
  • Maintaining precise journal dimensions for correct oil film and bearing clearance
  • Balancing the rotating assembly to minimise vibration and engine stress
  • Supporting consistent oil delivery through internal lubrication channels
  • Ensuring smooth power transfer across all RPM ranges
  • Forming the structural core of the bottom end assembly

A well-balanced standard-size crankshaft is essential for proper engine behaviour, especially in performance-prone flat-six units.

Why Crankshafts Commonly Fail

Despite being exceptionally robust, crankshafts can fail due to age, wear or incorrect operating conditions. Common causes include:

  • Oil starvation leading to journal scoring or bearing failure
  • Metal fatigue after years of high-RPM use or detonation events
  • Overheating compromising the metallurgical integrity of the crankshaft
  • Contamination from debris causing gouging or premature wear
  • Imbalance or improper machining from previous engine work
  • Severe knock or misfires bending or twisting the crankshaft
  • Prolonged high load driving accelerating fatigue in older engines

Symptoms typically include low oil pressure, knocking noises, excessive vibration, or visible scoring on journals during teardown.

Why You Should Replace a Worn or Damaged Crankshaft

Replacing a compromised crankshaft with a precision-built, standard size alternative engineered to match the original specifications ensures your Porsche 964 rebuild is stable, durable and capable of performing as intended.

Benefits include:

  • Restored bearing clearance and oil pressure stability
  • Reduced engine vibration and smoother power delivery
  • Stronger resistance to high-RPM and high-load conditions
  • Improved longevity of other bottom-end components
  • Prevention of catastrophic engine damage or seizure
  • More accurate balancing for performance and reliability

During an engine rebuild, the crankshaft is one of the most critical components to inspect and replace if any wear is detected.
