muge racing LS Knock Sensor Kit for GM 5.3 V8 – 2 Sensors + 2 Wiring Harnesses, OEM Fit & Corrosion-Resistant

muge racing's LS knock sensor and wiring harness kit is a direct-fit replacement set (two sensors + two harnesses) engineered to restore accurate knock detection for GM 5.3 V8 engines.

If your Chevrolet, GMC or Cadillac with an LS-series 5.3 engine is showing engine knock codes or intermittent misfires tied to the knock detection circuit, this muge racing kit supplies the sensors and harnesses that match the factory fitment and electrical connectors. The package includes two sensors and two harness assemblies so you can replace the components commonly changed together to eliminate false knock readings or wiring-related faults.

How does this kit match original equipment (OEM) fit and function?

The muge racing kit is designed around the same mounting geometry, connector type, and electrical resistance values used by GM, and it lists cross-reference part numbers to verify compatibility. Each sensor and harness has been examined for fitment and corrosion resistance so it installs like the factory parts.

• Replaces part numbers like 12601822, 12589867, 10456603 and related OEM references.
• Two sensors and two harnesses included for full-bank replacement on many V8 applications.
• Connector shells and pins sized to match factory plug shapes for a secure connection.

What are the performance and durability features of the knock sensors and harness?

muge racing uses materials and sealing techniques intended to resist engine-bay contaminants and wiring corrosion, improving long-term reliability over a worn or broken factory part. The harness insulation and terminals are selected to withstand heat and vibration typical of LS engine compartments.

• Corrosion-resistant wiring and connector terminals to reduce electrical faults.
• Heat-rated insulation to handle under-hood temperatures without cracking.
• Sensor bodies built to resist oil and moisture intrusion for consistent operation.

Which vehicles and engines does this kit work with?

This kit targets GM trucks and SUVs that use the 5.3L LS-series V8 engine where the listed cross-reference numbers apply. It commonly suits model families such as Chevrolet Silverado, Tahoe, Suburban, Avalanche and GMC Sierra, Yukon, plus select Cadillac platforms that share the engine architecture.

• Common fits: Chevy Silverado, Tahoe, Suburban, Avalanche.
• Also fits: GMC Sierra, Yukon, and compatible Cadillac V8 models.
• Confirm fit by checking your vehicle's existing knock sensor part number against the kit references.

How simple is installation and what comes in the box?

Installation is straightforward for a mechanically inclined DIYer or a professional technician: the kit includes both knock sensors and harness assemblies so you replace the sensor and the often-failed wiring at the same time. The connectors are keyed to fit properly, and the hardware follows factory mounting points.

• Kit contents: 2 knock sensors and 2 wiring harness assemblies for bank replacement.
• Direct-fit connectors and mounting geometry for straightforward swap-in.
• Installation requires basic hand tools and access to the engine upper area.

Who is this for: This muge racing knock sensor and harness kit is aimed at owners and technicians working on GM 5.3L LS engines who need a reliable, direct-replacement solution for knock detection faults. If you have check-engine codes related to knock sensors, intermittent knock circuit warnings, or you want to proactively replace aging wiring and sensors during engine service, this set supplies the matched components and OEM cross-reference numbers needed to restore correct operation.
