Alright, let’s talk about something that can really make a difference in your classic ride: the complete 4-piece window seal set. If you've got a Chevy or GMC from the '70s, this is a solid upgrade for those roll-up side windows. You know how it goes—old seals can let in the wind, water, and all sorts of noise. These seals are designed to fit snugly and keep your ride feeling more like a classic and less like a wind tunnel.
This set includes both inner and outer seals, which means you’re getting everything you need to make your windows operate smoothly. No more rattling when you hit the road or worrying about leaks when it rains. Whether you’re cruising in a '73 Blazer or a '80 C/K 10, these seals are made to fit just right.
- Fits: Chevrolet Blazer (1973-1974)
- Chevrolet C/K 10 (1973-1980)
- Chevrolet C/K 20 (1973-1980)
- Chevrolet C/K 30 (1973-1980)
- Chevrolet K5 Blazer (1975-1980)
- GMC C/K 15 (1973-1978)
- GMC C/K 1500 (1979-1980)
- GMC C/K 25 (1973-1978)
- GMC C/K 2500 (1979-1980)
- GMC C/K 35 (1973-1978)
- GMC C/K 3500 (1979-1980)
- GMC Jimmy (1973-1980)
These seals come straight from Brothers Trucks, so you know you’re getting OE-style quality. They’re built to last, just like your truck. Plus, when you’re restoring or maintaining a classic, it’s the little details that matter. So, if you’re tired of those old, cracked seals, grab this set and give your windows the refresh they deserve. Your ride will thank you!
