Aftermarket TPMS has quietly consolidated over the past few years. Where a shop owner once had to stock a dozen part numbers just to cover GM’s crossover and truck lines, a handful of well-built multi-application sensors now handle the same workload. The BH-Sens BL-ST-072 is a textbook example: one pre-programmed, clamp-in unit that replaces three separate GM OE numbers and carries 63 dedicated vehicle fitments — including the ENVISION, one of the most common imports-turned-domestics on American roads right now.
That kind of coverage matters less for marketing than for logistics. Fewer SKUs on the shelf means fewer mis-shipped orders, fewer returns from confused customers, and faster bay turnaround when a customer rolls in with a tire pressure light and a lunch break to burn.
Build and Design: What You’re Actually Buying
Baolong Technology isn’t a mystery-brand reseller. The company manufactures TPMS hardware for OEM assembly lines, and its BH-Sens aftermarket line draws on that same production base. In practical terms, that shows up where it counts: consistent RF output, housings that survive tire mounting machines, and stems that don’t corrode into the rim after two winters of road salt.
This particular sensor is clamp-in rather than rubber snap-in, with a metal valve stem secured by a nut inside the wheel. It arrives pre-programmed at 314.9/315 MHz — the standard North American GM frequency — which eliminates the programming step entirely. You mount it, run the vehicle’s relearn procedure, and move on.
Stem and Service Life Details
- Valve type: Aluminum clamp-in stem, serviceable with standard TPMS rebuild kits
- Frequency: Pre-programmed, no tool programming required
- Battery: Sealed internal cell, typically 5–7 years of real-world service
- OE references replaced: 12768826, 13516164, 13540604
That last bullet is the heart of the compatibility story, and it deserves its own section.
Coverage: Reading the OE Numbers Like a Parts Pro
The BL-ST-072 maps to three GM OE numbers, and together they span a wide slice of the General’s lineup — Buick, Cadillac, Chevrolet, GMC, plus Brilliance applications and others, totaling 63 dedicated fitments. Coverage generally runs across GM’s truck, SUV, and crossover production from roughly the mid-2010s onward, though the honest answer to “does it fit my exact car?” lives in those three numbers.
Here’s the shortcut most parts counters already know: every original sensor has its OE number molded into the housing. If the sensor currently in your wheel shows 12768826, 13516164, or 13540604, this unit drops straight in. If it doesn’t, stop and verify before ordering — GM switched frequencies and protocols enough times over the years that guessing is how dead sensors end up in return bins.
| Brand | Typical Applications | Matching OE Number |
|---|---|---|
| Buick | Envision and other crossovers | 13516164 |
| Chevrolet | Trucks, SUVs, sedans | 12768826 |
| Cadillac | Luxury SUV lines | 13540604 |
| GMC | Truck and utility platforms | 12768826 |
Treat the table as a starting point, not gospel. Model-year boundaries shift by market, and a 2019 built late in the cycle can share parts with a 2020 built early.
Verifying Fitment Before You Click “Buy”
Three checks take five minutes and prevent nearly every TPMS return I’ve seen:
1. Pull the OE number off your old sensor. Any tire shop will read it during a rotation or flat repair for free. Match it against the three numbers above.
2. Confirm your wheel takes a clamp-in stem. Look at the valve: metal stem with a visible retaining nut at the base means clamp-in. All-rubber stem means snap-in, and the two are not interchangeable.
3. Run the seller’s VIN or year/make/model lookup. Reputable suppliers maintain fitment databases tied to their SKUs. If a listing won’t confirm fitment for your specific VIN, buy somewhere that will.
One more field note: after installation, the sensor still needs to be registered to the vehicle. Most GM applications relearn through the key-fob-and-horn sequence, though a TPMS activation tool makes the job faster and works on stubborn trim levels.
The Verdict
For Envision owners staring down a dashboard warning and a quote for OEM sensors, the math here is hard to argue with — genuine OE-level hardware behavior at a fraction of dealer pricing, from a manufacturer that actually builds this stuff for automakers. Fleet operators and independent shops running mixed GM lots get even more value from the 63-fitment span, since one box covers half the parking lot.
Who should skip it? Anyone whose current sensor shows an OE number outside the three listed above, and anyone driving a model year that falls outside their supplier’s confirmed fitment window. The sensor itself is excellent; mismatched application is the only way to be disappointed by it.
If you’ve matched your OE number and want a straightforward swap, the BL-ST-072 is worth a close look — pre-programmed, clamp-in, and priced well below what the dealership will quote you. For most GM owners, it’s the least painful route back to a dark tire-pressure light.
