CNRAQR LS Gen 3 Knock Sensor Relocation Kit — M10 Gen 3, 36-inch Extension & Aluminum Brackets

CNRAQR's LS Gen 3 knock sensor relocation kit lets you move Gen 3 knock sensors from the valley pan to the block edge, using two aluminum brackets and a 36" extension harness to simplify maintenance and preserve factory sensors.

Designed for GM small-block LS Gen 3 engines, this kit accommodates M10-thread Gen 3 knock sensors and keeps the original sensors in service while relocating them to an accessible position. The package includes two machined aluminum brackets and a 36" extension relocation harness so technicians and DIYers can avoid removing the entire intake to service sensors. Note: this product is specifically for Gen 3 knock sensors and does not fit Gen 2 or Gen 4 systems.

Which engines and sensors will this relocation kit work with?

This kit is intended for GM LS Gen 3 engine families that use M10-thread knock sensors. It supports many common RPO codes while excluding some specific variants. Always confirm your sensor thread size and generation before ordering.

• Compatible RPOs: LS1, LS6, LQ4, LQ9, LM7, L59, LR4, L33
• M10 threaded Gen 3 knock sensors only
• Not compatible with Gen 2 or Gen 4 knock sensors
• Not recommended for LQ4 6.0 applications where noted

How does the relocation bracket make knock sensor service easier?

Relocating the sensors to the lower block edge removes the need to strip the intake manifold for access, cutting labor time and simplifying repeated sensor swaps. The included 36" harness maintains OEM wiring integrity while giving technicians enough length to route the harness neatly.

• Reaches remote sensor location with a 36" extension harness
• Aluminum brackets mount sensors at the block edge for accessibility
• Preserves original sensors and OEM-style wiring
• Reduces intake removal and overall teardown time

What should I know about installation and fitment?

Installation requires working in tight engine compartments and some disassembly of components that obstruct the bracket area. No printed instructions are included, so professional installation or a well-equipped workshop is recommended, particularly for 4x4 vehicles where space is limited.

• No installation manual included—plan for professional help if unsure
• Expect to remove surrounding parts for clearance during installation
• Ideal for shops and experienced home mechanics with basic tools
• Verify sensor thread size and engine compatibility before beginning

What comes in the box and what does each part do?

The kit supplies the essential hardware to relocate two knock sensors and extend their wiring to a lower, serviceable location. Each component is designed for durable fit and straightforward function when matched to a compatible Gen 3 engine.

• 2 × CNC-machined aluminum knock sensor relocation brackets for secure mounting
• 1 × 36" knock sensor extension relocation harness for routing and reach
• Hardware required for mounting (as applicable) to attach brackets to block edge
• Ships without step-by-step instructions—installer must be familiar with knock sensor wiring

Who is this for? The CNRAQR LS Gen 3 knock sensor relocation kit is for mechanics, engine builders, and knowledgeable DIY enthusiasts working on GM LS Gen 3 engines who want to preserve OEM sensors while making future servicing faster and less invasive. If you have a compatible M10-thread Gen 3 sensor and are comfortable with engine compartment disassembly or have shop access, this kit provides a durable, professional relocation solution.
