Professional Motorsport Shielded Wire – Spec 55 / MIL-C-27500 22AWG

We now offer genuine motorsport-grade MIL-DTL-27500 shielded cable built with M22759/32 tin-plated copper conductors and cross-linked modified Tefzel (XLETFE) insulation. These are 22AWG conductor sizes for minimum Cross Width.

Commonly referred to as:

• MIL-C-27500

• MIL-DTL-27500

• NEMA WC27500

• SPEC 55 cable

• 55A wire

• TE Raychem WC-27500 equivalent

This is the same style of shielded cable used in professional motorsport harnesses, aerospace wiring, and high-end ECU installations.

Available by the foot with in-stock quantities displayed. Spool options coming soon.

Available Configurations

We currently offer:

• Single Conductor Shielded

• 2-Conductor Shielded

• 3-Conductor Shielded

Additional conductor counts and spool options will be added as inventory expands.

Ideal Applications

This cable is designed for high-noise, signal-sensitive circuits including:

• Crank position sensor (CKP) such as the K24 Crank Angle Sensor connector.

• Cam position sensor (CMP)

• Knock sensor

• Wheel speed sensors

• CAN bus circuits

• Shielded analog inputs

• Motorsport data logging systems

Perfect for:

• Haltech installations

• FuelTech installations

• MoTeC harness builds

• K-swap shielded sensor wiring

• Professional motorsport harness construction
  

Why Use MIL-27500 Shielded Cable?

Unlike generic automotive shielded wire, MIL-DTL-27500 construction provides:

• Aerospace-grade insulation

• Superior chemical resistance

• High temperature tolerance

• Excellent EMI/RFI shielding

• Long-term durability in harsh engine bay environments

This is the correct way to wire crank and cam circuits in high-performance applications.
