JOYOJUMA Knock Sensor Kit for GM 4.8/5.3/6.0L — 2-Sensor Direct-Fit Harness, Vibration-Tested

JOYOJUMA Knock Sensors Wiring Harness Kit is a complete replacement set that restores knock sensor connectivity on GM 4.8L, 5.3L and 6.0L V8 engines.

This kit bundles two knock sensors and a dedicated harness engineered to match factory fit and function on many Chevy, GMC, Cadillac and Hummer vehicles. Built from corrosion-resistant materials and validated by vibration testing, the package replaces several OE part numbers so you can swap worn or damaged sensors and wiring without modifying the intake manifold or vehicle electronics.

Which vehicles and engines will this kit fit?

The kit was designed for a wide range of GM trucks and SUVs using the 4.8L, 5.3L and 6.0L engines. It covers many model years for Silverado, Sierra, Suburban, Tahoe, Avalanche, Yukon, Camaro and certain Hummer applications where the original part numbers match.

• Compatible OE references: 12601822, 12589867, 10456603 and related numbers.
• Common fits: Chevy Silverado 1500/2500/3500, GMC Sierra 1500/2500/3500, Suburban, Tahoe, Yukon.
• Also applicable to select Cadillac, Pontiac and Buick models that use the same engine family.
• Check engine displacement (4.8L/5.3L/6.0L) and OE number for exact match.

How does the JOYOJUMA kit improve reliability and longevity?

Materials and assembly focus on durability: the wires use corrosion-resistant sheathing and the sensors are vibration-tested to help withstand heat, road vibration and underhood contaminants. That reduces failure points compared with brittle or corroded original components.

• 100% accelerometer vibration-tested sensors for long-term performance.
• Durable harness construction resists cracking and corrosion.
• Plug-and-play connectors that mimic OE electrical fitment.
• Two sensors included—ready for both driver and passenger sides.

What comes in the package and what should I expect during installation?

The box contains two knock sensors and one sensor harness tailored for the intake manifold routing found on targeted GM V8 engines. Installation is straightforward for mechanically skilled DIYers or a professional technician, and no special programming is required when replacing direct-fit sensors and harnesses.

• Included: 2 x knock sensors, 1 x knock sensor harness.
• Direct-replacement design—no splicing or custom wiring needed.
• Typical tools: hand ratchet, sockets, and basic hand tools; torque sensor to OE spec recommended.
• Allow time to remove intake components on some models for access.

Are there warranties or support if something goes wrong?

JOYOJUMA backs this kit with a 14-month warranty that covers manufacturing defects and premature failures under normal use. Customer service can provide exchange or refund options if you encounter compatibility or quality issues.

• 14-month limited warranty included with purchase.
• Manufacturer support for exchanges or refunds on covered issues.
• Confirm OE part numbers before ordering to reduce returns.

Who is this for: This wiring harness and sensor set is intended for owners and technicians working on GM trucks and SUVs with 4.8L, 5.3L or 6.0L V8 engines who need an affordable, factory-style replacement. It suits anyone replacing failed knock sensors or damaged harnesses and who wants a tested, direct-fit solution that restores reliable sensor signals without complex electrical work.
