The decision to replace a 58x crankshaft with a 24x crankshaft in an engine depends on various factors. It includes compatibility, engine design, and performance goals.
Can I Put A 24x Crankshaft Instead Of A 58x? No, my research says that you cannot directly replace a 58X crankshaft with a 24X crankshaft, though you can do the vice versa. A motor originally with a 24X configuration can be converted to 58X by changing parts, including the reluctor wheel on the crankshaft, though this process may require specialized labor and components.
Let’s see why you cannot put a 24x crankshaft instead of a 58x. What are the drawbacks, and what can you do in such a situation?

Can I Put A 24x Crankshaft Instead Of A 58x? An Overview
It’s essential to ensure that the 24x crankshaft is compatible with the engine block, connecting rods, pistons, and other components. Also, the crankshaft’s timing system should align with the engine’s ignition system.
Before delving into what’s the difference between 24x and 58x, let’s explore their key characteristics and applications. These crankshaft designs are integral to modern engines, each serving distinct purposes.
| Aspect | 24X Crankshaft | 58X Crankshaft |
|---|---|---|
| Tooth Count | 24 evenly spaced teeth on reluctor | 58 evenly spaced teeth on reluctor |
| Compatibility | Used in older GM LS series engines | Used in newer GM LS series engines |
| Engine Control | Requires 24X-compatible electronics | Requires 58X-compatible electronics |
| Conversion | Can be converted to 58X with module | Conversion to 24X is not straightforward |
| Performance Tuning | Limited aftermarket support | Wide array of tuning options available |
| Sensor Arrangement | Employs older sensor setup | Utilizes newer, more advanced sensors |
| Compatibility | Not directly compatible with 58X systems | Compatible with 24X systems with module conversion |
| RPM Performance | May have limitations in high-RPM use | Better suited for high-RPM applications |
| Engine Models | Found in older LS1, LS6 engines | Found in newer LS3, LS7, LS9 engines |
| Vehicle Applications | Older model vehicles, swaps | Newer model vehicles, performance builds |
5 Cons of Putting A 24x Crankshaft Instead of 58x
You know you can use 58x instead of 24, but you cannot do the reverse. This might make you wonder why. Here is why you cannot do this.
1. Differing Crankshaft Tooth Patterns
One of the primary reasons why you cannot simply replace a 58X crankshaft with a 24X crankshaft is the significant difference in their tooth patterns on the reluctor wheel. The terms “24X” and “58X” refer to the number of evenly spaced teeth on these reluctor wheels.
These teeth interact with sensors to provide crucial information about the crankshaft’s position and speed. In turn, they help the engine’s control module (ECM) manage fuel injection and ignition timing.
2. Incompatible Electronics and Control Systems
The tooth pattern on the reluctor wheel directly corresponds to the timing and synchronization of the engine’s operations. A 24X crankshaft is designed to work with an ECM and wiring harness specifically configured for 24X signals.
Attempting to use a 24X crankshaft with a 58X ECM would result in a mismatch between the tooth pattern and the control system’s expectations. This misalignment would lead to incorrect timing, improper fuel delivery, and, ultimately, engine performance issues.
3. The complexity of Control System Adaptation
There are conversion modules available to adapt a 58X motor to run on a 24X harness. The reverse conversion is not as straightforward. This is because the 24X signal is inherently less complex than the 58X signal. The 58X system offers more detailed information, enabling more precise engine control.
Trying to retrofit a 24X crankshaft to a 58X system would require not only changing the reluctor wheel but also potentially reconfiguring or reprogramming the ECM to handle the increased complexity of the 58X signal.
4. Sensor Placement and Configuration
Beyond the reluctor wheel, the sensor placements and configurations are also different between 24X and 58X systems. The locations of the sensors that interact with the reluctor wheel are specific to each design.
Therefore, even if you were to swap the reluctor wheel, ensuring that the sensors align properly with the new tooth pattern is a significant challenge.
5. Professional Expertise and Costs
Converting from a 24X to a 58X crankshaft requires specialized knowledge, tools, and skills. Mechanics or engine builders experienced in these modifications are essential to ensure correct installation, alignment, and programming. It will increase the cost very much.

FAQs
Here are some related queries based on switching 24x crankshaft instead of 58x.
Q1:- How to know which crankshaft I need?
To determine the required crankshaft, examine the crank sensor harness connection. A black sensor indicates a 24X setup, while a gray sensor (58X) suits GMPP harness compatibility.
Q2:- Can I use a 24x crankshaft instead of 58x in 2000 PCM?
No, using a 24x crankshaft instead of a 58x in a 2000 PCM is not straightforward due to differing reluctor wheel patterns and associated electronic compatibility issues.
Conclusion
While it might be tempting to replace a 58x crankshaft with a 24x version, it’s crucial to consider the intricate electronic and mechanical factors at play. The compatibility of reluctor wheel patterns and engine control systems is pivotal for proper engine performance.
Remember, I’m here to provide guidance, but consulting experts and following manufacturer recommendations are vital before embarking on any such modification.
