Knock Sensor Relocation Bracket Kit with Extension Harness Fit Gen III LS1 LM7 LQ4 4.8L 5.3L 6.0L V8 Engines.

Upgrade your Gen III V8 engine with this complete knock sensor relocation bracket kit, built as an aftermarket upgrade for 1997-2007 LS-series power platforms. Whether you’re completing an engine swap, installing upgraded headers, or tired of disassembling the intake manifold just to access factory sensors, this kit delivers a durable, long-term practical solution.This package includes 2 precision-machined aluminum mounting brackets, a 36-inch dual-circuit extension harness, 2 mounting screws, and a roll of sealant tape. The relocation installation is simple and works with standard hand tools only. It shifts your existing knock sensors from the valley pan to side mounting points on the engine block, keeping sensor functionality intact while clearing extra space for aftermarket parts.Each bracket comes with multiple threaded mounting holes for fully customizable positioning. This multi-port layout eliminates fitment conflicts with long-tube headers, aftermarket motor mounts and accessory drive hardware, enabling a tidy, interference-free install tailored to your modified engine setup.Manufactured from solid high-grade aluminum with precision CNC machining, these brackets deliver lasting structural strength and steady sensor positioning. The included sealant tape adds extra defense against dust and moisture, supporting reliable performance for daily street driving and high-performance modified builds alike.After relocation, knock sensors stay fully accessible for future inspections, maintenance or replacement. You no longer need to remove the intake manifold or valley pan to service the sensors, cutting down extensive disassembly work and drastically simplifying routine LS engine maintenance jobs.Works with 4.8L, 5.3L, 5.7L and 6.0L engine displacements including LS1, LM7, LR4, LQ4, LS6, L59, LQ9, LM4 and L33.
