CNRAQR LS Gen 3 Knock Sensor Relocation Brackets with 36-inch Harness – GM LS Engines

Overview

The CNRAQR LS Gen 3 Knock Sensor Relocation Brackets with a 36-inch extension harness are designed to streamline sensor replacement and routing on GM LS Gen 3 engines. Instead of reaching into the valley pan, sensors can be positioned along the bottom edge of the engine block, which can simplify service access and reduce the need for repeated intake removal during maintenance. The kit combines rugged aluminum brackets with a long extension harness, offering a tidy, durable solution for sensor relocation.

Crafted from durable aluminum, the kit provides two brackets and a long extension harness that helps you align the sensors in a tidy, secure path. The M10 threaded fittings ensure a solid fit with Gen 3 knock sensors, while the kit remains specific to the Gen 3 family to preserve compatibility and performance characteristics while you service or modify the engine bay.

What’s included

• 2 aluminum knock sensor brackets
• 1 36-inch knock sensor extension relocation harness

Fitment and compatibility

• Thread size: M10
• Designed for Gen 3 knock sensors only
• Not compatible with Gen 2 or Gen 4 sensors
• Fits engine RPO codes: LS1, LS6, LQ4, LQ9, LM7, L59, LR4, L33
• Not applicable to LQ4 6.0

Notes on installation and use

Note: No installation guide is included. In some 4x4 platforms, removing the intake and servicing from a factory location can be simpler. The mounting area is tight; you may need to temporarily remove adjacent components. For best results, consider professional installation or a well-equipped workshop.

How this helps in practice

This relocation kit helps keep Gen 3 sensors accessible without forcing you to repeatedly pull the intake. It also supports neat sensor routing that traces a neat path along the engine block edge, which can reduce clutter and potential interference. Builders value the kit for its solid aluminum construction and purpose-built fitment that aligns with the engine bay layout of Gen 3 LS builds.

What you get and what to expect

• Durable aluminum brackets designed for long-term use
• A 36-inch extension harness that adds routing flexibility
• A compact kit that integrates with established LS Gen 3 sensor layouts
