Geometry TPMS Fitment: The 433MHz Cross-Brand Reality

Lead: Geometry owners trying to price out a TPMS service are in for a shock. The dealer lists a new sensor for anywhere from $90 to $130, plus programming, and often adds a backorder because the part ships from overseas. Meanwhile, an aftermarket sensor with the same 433MHz operating frequency and the exact GM OE number 26670584 sits on a shelf at a fraction of that price. The catch: it’s labeled for Buick and Chevrolet. So is it a Geometry part or not?

Quick Answer: It can be. The BL-ST-087 from BH-Sens is a 433MHz TPMS sensor calibrated around OE# 26670584. Frequency and protocol — not the make on the box — determine whether it works in a Geometry. Check three things before ordering: your old sensor’s OE number, its frequency marking, and the programming protocol your car accepts.

Then body.

Paragraph 1 — the cross-brand reality:

Chinese vehicle brands like Geometry don’t build TPMS sensors in-house. They buy from the same tier-one electronics suppliers that feed global marques. The result is that a sensor carrying a GM-style OE number can be the identical silicon as one used in a Geometry EV. Geely, which owns Geometry, has over the years shared TPMS sourcing across brands, and the 433MHz band is the dominant standard for these systems. That’s why a shop with a TPMS tool plus a sensor bin full of BH-Sens parts can program a Buick one minute and a Geometry the next.

Paragraph 2 — what to verify:

• Frequency: pull the old sensor, check for “433MHz” marking.
• OE number: compare with 26670584 or a listed cross.
• Valve type and torque spec.
• Battery shelf life.

Checklist table.

Paragraph 3 — OE vs aftermarket price analysis:

Dealer sensor $90–$130; the BH-Sens… $? — I can say “roughly half” or “about $25–$35” but I shouldn’t invent exact pricing. I’ll keep it comparative: “a fraction of the dealer price.”

Paragraph 4 — where to buy:

Longwei Parts direct sourcing from China, so you’re buying from the same factory pipeline, with fitment validation. The product rec.

Geometry TPMS Fitment: The 433MHz Cross-Brand Reality

Geometry owners are starting to ask a question that would have sounded heretical two years ago: “Can I fit a GM sensor in my EV?” The answer, in a growing number of cases, is yes. And the part making them ask is the BL-ST-087, a BH-Sens 433MHz TPMS sensor built around GM OE# 26670584. It’s listed for Buick and Chevrolet, but that box label says more about distribution channels than it does about engineering.

Here’s the short version: if your Geometry’s original sensor is stamped 433MHz and carries a cross-reference to 26670584, the BL-ST-087) is your replacement. If not, keep looking. Frequency, protocol, and physical fit are the only facts that matter — the brand logo on the catalog page is just marketing.

The Cross-Brand Reality

Geometry doesn’t manufacture TPMS sensors. No one does, really — tire pressure monitoring is a specialized electronics niche dominated by a handful of tier-one suppliers, and those suppliers sell the same chipsets to GM, Geely, and everyone else placing large-enough orders. Geely, which owns Geometry, has shared TPMS hardware and platform electronics across several of its brands, and the 433MHz standard remains the common language. That’s why specialty aftermarket manufacturers like BH-Sens can produce one sensor, validate it against a large cross-reference, and sell it into multiple makes.

The practical consequence: a shop with a TPMS scan tool and a bin of BH-Sens sensors can program a Chevrolet Equinox in the morning and a Geometry C in the afternoon using the same part number. That’s not a hack — it’s how the supply chain actually works once you buy from a factory-direct source.

What to Verify Before You Buy

Don’t assume. Pull the old sensor and check:
