Masoll TPMS Sensor Kit for GM Vehicles — Gen 2 4-Pack with EL-50448 Relearn Tool, Dual-Frequency (315/433MHz)

Masoll TPMS Sensor Kit is a complete DIY tire-pressure monitoring solution for GM vehicles that includes four dual-frequency sensors and the EL-50448 relearn tool so you can replace factory sensors and reset the TPMS light at home.

If your GM vehicle (Chevy, GMC, Buick, Cadillac, Pontiac) is displaying a TPMS warning or you need a reliable aftermarket replacement, this Masoll Gen 2 kit provides broad compatibility, an easy home-install workflow, and durable sensors engineered for trucks, SUVs and cars. The set pairs OEM-style internal sensors with a relearn programmer so you don’t need a dealer visit — designed to match factory performance while simplifying installation.

Which GM models and years will these Masoll sensors work with?

The Gen 2 Masoll TPMS sensors cover a wide range of GM-branded vehicles made after 2006, including multiple Chevy, GMC, Buick, Cadillac and Pontiac models. Coverage is expanded versus the prior generation to better support pickups like Silverado and Sierra as well as SUVs and sedans. For exact fitment, consult the vehicle list in the product description or verify your original sensor frequency.

• Designed for GM vehicles 2006 and newer (full vehicle list available in product details)
• Engineered for cars, SUVs and pickup trucks including Silverado and Sierra
• Dual-frequency support removes guesswork about OEM radio band

How easy is it to install and reset the TPMS light yourself?

Masoll built this kit for DIY installation: the sensors screw onto existing valve stems and the included EL-50448 programming tool performs the relearn procedure. Typical install and relearn can be completed in about five minutes per vehicle once you have the steps and the tool. This avoids dealer trips and specialized equipment while restoring proper TPMS operation.

• Sensors attach to valve stems — no special machining required
• EL-50448 tool included to program and sync sensors to the ECU
• Quick relearn procedure commonly completed in minutes

What technical advantages does the Gen 2 Masoll TPMS offer?

The second-generation Masoll sensors add wider vehicle coverage, stronger signal transmission and a more robust housing compared with the first generation. Each sensor supports both 315MHz and 433MHz frequencies in one unit to ensure compatibility across different GM models. Low power design and replaceable batteries deliver reliable service life with high accuracy for pressure readings.

• Dual-frequency 2-in-1 (315MHz and 433MHz) reduces compatibility issues
• Improved signal strength and ruggedized construction for trucks and SUVs
• Approximately two years battery life with replaceable battery and ~1.5 PSI accuracy

What comes in the box and what should I expect after installation?

The kit contains four Masoll internal TPMS sensors and the EL-50448 TPMS relearn tool so you have everything required to replace and program sensors at home. After installation and relearn, the TPMS warning light should clear and the ECU will report accurate tire pressures. As with any aftermarket sensor, verify correct IDs and perform a test drive to confirm stable radio reception and sensor reporting.

• Kit includes 4 Masoll Gen 2 sensors plus EL-50448 programming tool
• Factory-style internal sensors intended as direct replacements
• Test and verify sensor IDs and TPMS light clearance after programming

Who this is for: Owners of GM-family vehicles (Chevrolet, GMC, Buick, Cadillac, Pontiac) who want a cost-effective, DIY replacement for malfunctioning or aging factory TPMS sensors. It’s a practical choice for drivers of trucks and SUVs who need stronger signal performance and dual-frequency compatibility, or for anyone preferring to avoid dealer service for TPMS relearn and replacement.
