1982-1993 Chevy S10 & GMC S15 Weatherstrip: Every Seal on the Truck, Piece by Piece
The S10 has quietly become one of the best first project trucks you can buy. They're everywhere, they're cheap, parts are still made — and after thirty-plus years, the rubber is always the same story: the doors leak, the windows rattle, the windshield molding has gone chalky, and the back glass has a slow drip that finds the seat belt bolts.
Here's the good news. Almost every seal on a first-generation S10 is still reproduced, and the fitment is unusually clean compared to a lot of classic-truck work. This guide walks the whole truck, names the part for each job, and tells you where the complete kit makes more sense than buying pieces.
First: which truck do you actually have?
GM built this platform under a lot of badges, and the year ranges are staggered — the pickup and the Blazer didn't start or end in the same year. Precision publishes the same application list on nearly every seal in this family, and it reads:
- 1982-1993 Chevrolet S10 pickup
- 1982-1990 GMC S15 pickup
- 1983-1994 Chevrolet S10 Blazer
- 1983-1991 GMC S15 Jimmy
- 1991-1993 GMC Sonoma
- 1992-1994 GMC Jimmy
- 1991-1994 Oldsmobile Bravada (listed on some pieces, not all — check the individual part)
Note the offsets. A 1994 Blazer takes these seals; a 1994 pickup does not — the pickup changed for 1994. If you're on a 1994-and-later S10 pickup, this guide isn't your truck. (We do carry seals for the later trucks, but they're separate part numbers and several are out of stock as this is written, so we're not going to point you at them here.)
The doors — three separate jobs people mix up
"Door seal" on an S10 can mean three different parts, and buying one when you needed another is the single most common ordering mistake on this truck.
1. The main door seal (body side)
dwp1110-82 — 1982-1993 Chevrolet GMC S10 Pickup Blazer Jimmy Front Door Seal Kit, $68.25. This is the pair, left and right, that seals the door against the cab opening. If your doors whistle at freeway speed or the carpet is damp on the kick panel, start here.
2. The upper cab-opening seal
dwp 1111 82 — $46.71. Precision's own note on this one is worth reading twice: "This seal mounts on the upper part of the cab opening... Please inspect your original seal(s) before ordering. This product is not a compatible replacement for the bulb style upper door seals found on some models." Some of these trucks came with a bulb-style upper seal, and this part will not replace it. Look at yours before you order.
3. The glass run channel
grb 1110 82 — $44.86 each. This is the channel the door glass rides in, front, top and rear. It presses in, and — again quoting the vendor — "You must re-use your existing metal brackets that are attached to the existing glass run seal." Don't throw the old ones away. This SKU covers one door, so a full truck is two.
Window felt: fuzzies only, or fuzzies plus run channel?
This is the real decision on the S10, and the two kits look almost identical in a search result.
| Part | What you get | Price |
|---|---|---|
| wfk1110-82 | 4-piece — inner and outer beltline "fuzzies" for both front doors. The strips that wipe the glass as it rolls up. | $77.66 |
| wfk1111-82 | 6-piece — the same windowfelts plus the run channels front and rear of the glass. | $110.80 |
Rule of thumb: if the glass rattles or drops crooked, you need the run channels too, so buy the 6-piece. If the glass tracks fine and you're just chasing water and wind noise at the belt line, the 4-piece does the job for $33 less.
Beltline molding
wfr 1111 82 — $29.43. This is the individual molding that mounts on the door and sweeps the outside of the glass. One per door. Buy two if you're doing the truck.
Windshield reveal molding
wfsd1160 — $31.27. A one-piece, three-sided PVC molding with no corner welds. The listing calls it "a must when replacing a new windshield" — and that's the honest use case. It's cheap, it's the part everyone forgets to order until the glass shop is standing in the driveway, and a thirty-year-old one always comes off in pieces. If glass is coming out, order this at the same time.
Blazer owners: the Blazer-specific version is wfs d1160 r-100, $81.87.
Rear glass
wbl6425 — $65.85. Black rubber rear window seal for the pickup. One important line from the listing: "THIS SEAL DOES NOT ACCEPT FACTORY TRIM MOLDINGS." If your truck runs the chrome trim around the back glass and you want to keep it, this is not the gasket — ask us before ordering.
This is one of our steadier-selling parts across the whole store, which tells you something about how these trucks age: the back glass leaks first.
The Blazer's quarter windows
qfs 6563 — $27.77, 1983-1994 S10 Blazer 2-door. Not applicable to the pickup.
Pieces, or the kit?
There's a complete kit for this truck: CWK 1110 82-S10, $165.99. Its own description says it fits 1982-1993 Chevrolet S10, 2-door standard cab and 2-door extended cab pickup, and lists the contents as:
"Door Weatherstrip For Cab, Upper Channels, Windshield Reveal Molding, Beltline Kit, Rear Window Seal."
Five jobs. Here's what those same five jobs cost if you buy them one at a time off our own shelf:
| Job | Individual part | Price |
|---|---|---|
| Door weatherstrip, cab | dwp1110-82 | $68.25 |
| Upper channel | dwp 1111 82 | $46.71 |
| Windshield reveal molding | wfsd1160 | $31.27 |
| Beltline (2 doors) | wfr 1111 82 × 2 | $58.86 |
| Rear window seal | wbl6425 | $65.85 |
| Bought separately | $270.94 | |
| CWK 1110 82-S10 kit | $165.99 | |
Be straight with yourself about one thing before you click, though: Precision may supply a slightly different mix inside the kit than the individual part numbers above. The component list is theirs, quoted as written, but we can't guarantee a part-for-part match. If you only need one specific piece — say, just the back glass seal — buy that piece. The kit earns its keep when you're doing the whole truck at once, which on a thirty-year-old S10 is usually the right call anyway.
Also worth noting: the kit does not include the window felt / run channel set. That's the wfk1111-82 above, and on a truck with rattly glass you'll want it.
Where to shop the rest
Browse the wider categories if you want to see what else fits: door seals, window channels & felt, beltline moldings, windshield seals, and rear window seals.
One last honest note
Rubber parts are the cheapest thing you'll ever do to a truck that changes how it feels to drive. A resealed S10 is quieter, drier, and stops fogging the inside of the glass every damp morning. It's also the kind of job that goes wrong quietly — order the wrong upper seal and you'll find out three hours in. Check what's on your truck before you order, and if you're not sure which version you've got, send us a photo. We'd rather answer a question than process a return.
