CNRAQR LS Gen 3 Knock Sensor Relocation Brackets 36-inch Extension Harness, Aluminum M10

CNRAQR LS Gen 3 Knock Sensor Relocation Brackets and 36" extension harness let you move Gen 3 knock sensors from the tight valley pan area to the lower engine block for easier access and service.

This aluminum relocation kit is built for GM LS Gen 3 small-block engines and includes two precision-machined brackets plus a 36-inch extension relocation harness so the OE knock sensors remain functional when repositioned. The kit preserves factory sensors while removing the need to pull the intake manifold for every replacement, saving time on diagnostics and repairs. Note: This product is only compatible with Gen 3 knock sensors (M10 thread) and does not include an installation manual; professional installation or a well-equipped workshop is recommended due to restricted access on many vehicles.

Will this kit work with my LS engine?

Check the engine RPO code and knock sensor thread before buying. The CNRAQR kit fits many Gen 3 variants but is not universal across all LS families.

• Compatible RPOs: LS1, LS6, LQ4, LQ9, LM7, L59, LR4, L33.
• Knock sensor thread: M10 — required for compatibility.
• Not compatible with Gen 2 or Gen 4 knock sensors, and not applicable to LQ4 6.0 installations.
• Verify your engine’s generation and sensor thread before purchase.

How does the relocation bracket change maintenance?

Moving the knock sensors to the lower block edge reduces the need to remove the intake manifold when swapping or testing sensors. That lowers labor time and simplifies troubleshooting, especially on engines that otherwise require significant disassembly.

• Relocation eliminates repetitive intake removal for sensor access.
• 36" extension harness gives reach and routing flexibility.
• Aluminum brackets provide durable mounting and heat resistance.
• Sensors stay factory original; no aftermarket sensor needed.

What’s included and what should I expect during installation?

The kit ships with two machined aluminum brackets and a 36-inch extension harness so you can retain your car’s existing knock sensors. Because the sensors are often tucked into tight spaces, surrounding components may need to be removed first, and the manufacturer does not include step-by-step instructions.

• Included: 2 aluminum knock sensor brackets, 1 x 36" extension relocation harness.
• No printed installation guide is provided—plan for professional help if unsure.
• Some applications (4x4 or tight engine bays) may still require intake removal or extra disassembly.
• Follow standard torque and wiring protection practices when mounting and routing the harness.

Does this affect engine performance or the factory wiring?

The relocation brackets and harness are designed to preserve the original sensors and maintain factory signal integrity when installed correctly. Proper routing and secure mounting are important to avoid strain or exposure to excessive heat or mechanical damage.

• Retains OE knock sensors and their electrical characteristics.
• 36" harness gives room for safe routing away from hot or moving parts.
• Use protective conduit or heat shielding where necessary.
• Observe correct connector orientation and secure fasteners to prevent signal issues.

Who is this for: The CNRAQR LS Gen 3 knock sensor relocation kit is aimed at mechanics, performance shops, and experienced DIYers who own Gen 3 LS engines and want quicker sensor access without replacing OE sensors. If you drive a vehicle with compatible RPO codes and are comfortable with engine-level work or can use a professional installer, this kit reduces downtime and simplifies future knock sensor service. Avoid this product if your engine uses Gen 2 or Gen 4 sensors or if you cannot perform moderately complex engine wiring and mounting tasks.
