higherbro O2 Sensor Kit for 1996–2000 Dodge Ram — 2PCS Upstream & Downstream Match-Fit for 3.9L/5.2L/5.9L

higherbro 2PCS Oxygen O2 Sensor 1 & 2 is a matched upstream and downstream oxygen sensor pair designed to restore accurate exhaust sensing on compatible 1996–2000 Dodge Ram 1500/2500/3500 engines. This paired O2 sensor kit replaces both the sensor before the catalytic converter (upstream) and the sensor after it (downstream) to help your engine control system read exhaust oxygen levels more reliably. Each sensor is manufactured to fit the listed Dodge Ram 3.9L, 5.2L and 5.9L petrol engines from model years 1996–2000 where specified. higherbro includes a one-year unlimited mileage quality guarantee and advises buyers to confirm vehicle fit using the site’s "Select Your Vehicle" tool before purchase.

Will these sensors fit my Dodge Ram?

Check fitment carefully: this kit is built for specific 1996–2000 Dodge Ram models and engine sizes. Verify your truck’s make, model year, and engine displacement against the fitment list to ensure compatibility.

• Fits 1996–2000 Dodge Ram 1500: 3.9L, 5.2L (1996–1999 for 5.2L), and 5.9L
• Fits 1996 Dodge Ram 2500: 5.2L; Fits 1996–2000 Ram 2500: 5.9L
• Fits 1996–1999 Dodge Ram 3500: 5.9L
• Confirm with the "Select Your Vehicle" check on the product page before ordering

How does replacing both upstream and downstream sensors help performance?

Replacing both sensors at once gives the engine control unit consistent, matched signals from before and after the catalytic converter. Matched sensors reduce diagnostic errors, can stabilize fuel trim readings, and help the vehicle run closer to the intended air-fuel ratios.

• Upstream sensor provides fast-response oxygen readings to the ECU
• Downstream sensor monitors catalytic converter efficiency
• Paired replacement avoids mismatched aging effects between sensors
• Can help clear related diagnostic trouble codes when sensors are the root cause

What should I expect when installing these higherbro sensors?

Installation typically involves unbolting the old sensors, unplugging the electrical connectors, and fitting the new sensors into the exhaust bung with the correct torque. Basic hand tools and a proper oxygen-sensor socket make the job straightforward for a mechanically inclined owner, though a shop can complete the job quickly if preferred.

• Includes two sensors: upstream (bank 1, sensor 1) and downstream (bank 1, sensor 2)
• Use anti-seize on threads if recommended by the installer (check vehicle service manual)
• Reconnect electrical harness securely to avoid false readings
• After installation, allow the engine to run through a drive cycle to clear adaptive trims

What warranty and quality assurances come with this kit?

higherbro backs this 2-piece oxygen sensor set with a 1-year unlimited mileage quality guarantee, offering buyers confidence in manufacturing and materials. Review the seller’s return and warranty terms on the product page for claim procedures and any exclusions.

Always confirm vehicle compatibility with the "Select Your Vehicle" tool and consult a professional if you’re unsure about installation.

FAQ

Q: Do these sensors fit my 1998 Dodge Ram 1500 5.9L?

A: Yes — this kit fits 1996–2000 Dodge Ram 1500 with the 5.9L engine, but confirm with the product’s "Select Your Vehicle" tool before buying.

Q: Will replacing both sensors clear my check engine light?

A: If faulty O2 sensors triggered the light, replacing both can clear related codes after the ECU completes a drive cycle; other faults may still keep the light on.
