CHENHO LS Gen III Knock Sensor Relocation Brackets - 6061 CNC Aluminum, 41" Extended Harness

If you own a 1997–2007 GM Gen III LS V8 (LS1, LM7, LR4, LQ4, LS6, L59, LQ9, LM4, L33), this kit lets you move the factory knock sensors out of the valley pan without removing the intake manifold. The package includes two 6061 CNC-machined aluminum brackets, a 41-inch extension harness pre-wired to match Delphi connectors, mounting bolts, and repair gloves. It preserves OEM sensor function while replacing fragile plastic mounts with robust metal hardware.

How does relocating the knock sensors save time during service?

By moving sensors to the lower edge of the block, you avoid disassembling the intake to reach sensors buried in the valley. That reduces labor for routine replacement or diagnostic work and lowers the risk of intake gasket disturbance.

• No intake manifold removal for sensor access in most installations
• 41" extended harness reaches factory wiring without splicing
• Pre-wired color-coded connectors fit Delphi OEM plugs for plug-and-play

Will this kit fit my specific LS engine and sensors?

The brackets are engineered for GM Gen III engines produced 1997–2007 and accept OEM Gen III knock sensors with M10 threads. They are compatible with common Gen III codes listed and match OEM part numbers for straightforward replacement.

• Compatible with LS1, LM7, LR4, LQ4, LS6, L59, LQ9, LM4, L33 engines
• Works with Delphi-style connectors and OEM wiring harnesses
• Not compatible with Gen II/Gen IV sensor types—check thread and connector

What makes the CHENHO brackets more reliable than stock mounts?

These brackets are CNC-machined from 6061 billet aluminum, resisting heat and corrosion better than factory plastic clips. The solid metal construction minimizes movement and sensor stress in high-vibration or high-temperature engine bays.

• 6061 billet aluminum resists high temperatures and corrosion
• Precision CNC machining ensures consistent sensor orientation and fit
• Includes quality hardware and gloves for secure installation

Are there installation considerations or limitations I should know?

Installation is designed to be straightforward but some tight engine bays or 4WD layouts may require professional help. Certain 4WD applications may need both sensors mounted on the passenger-side bracket; verify sensor placement before starting.

• Professional installation recommended where clearance is limited
• Some 4WD vehicles require both sensors on the passenger-side bracket
• Does not fit Gen II or Gen IV knock sensors

Who is this for: The CHENHO LS Gen 3 Knock Sensor Relocation Brackets are built for mechanics, performance builders, and DIY LS owners who want durable, service-friendly sensor placement and OEM-compatible wiring. Choose this kit if you need a long-lasting upgrade to fragile plastic sensor mounts, want to simplify knock sensor maintenance, or are preparing an engine bay for frequent tuning or high-heat environments. The kit's OEM-style connectors, M10 thread fit, and 24-month warranty provide confidence for everyday drivers and track-focused builds alike.
