Keep the Windows Open Rain or Shine on Your Classic CK Pickup
The AVS 94231 Ventvisor Outside Mount Window Deflectors give 1988 to 1999 Chevrolet CK and GMC C/K extended cab owners a clean, durable way to run the windows cracked in any weather. The 94231 is a 4-piece smoke-tinted set precision-engineered to match the exact window contours of these trucks, mounting above the glass on the outside of the door frame with 3M automotive adhesive. No drilling, no clips, no modifications. Once installed, the 94231 channels fresh air into the cab while deflecting rain, wind, and highway debris outward, so you can keep the interior ventilated without getting soaked or blasted with road noise. Made in the USA in Lawrenceville, GA, backed by a Limited Lifetime Warranty to the original vehicle owner.
Key Features
- Outside Mount Design: The AVS 94231 mounts above the window frame on the exterior door skin, following the roofline contour of the 1988 to 1999 CK extended cab for a factory-finished look with no interior interference
- Impact-Resistant Acrylic Construction: Thick, high-grade acrylic resists cracking, chipping, and fatigue from stone strikes, branches, and road debris tested through 15,000 miles of all-season driving without deformation
- UV and Scratch Resistant Smoke Finish: The dark smoke tint on the 94231 is UV-stabilized to resist fading and yellowing even after years of direct sun exposure in Florida and southwestern heat
- 3M Automotive Adhesive Installation: Pre-applied 3M VHB pressure-sensitive tape bonds directly to the painted door frame with no drill holes, no clips, and no damage to the factory finish
- Car-Wash Safe: Once the 24-hour cure is complete, the 94231 holds firm through automated car washes, subzero mornings, and triple-digit summer days without lifting or shifting
- Made in the USA: Manufactured by AVS in Lawrenceville, Georgia, with global materials
- Limited Lifetime Warranty: Covers defects in materials and workmanship for the life of the original vehicle owner. Warranty is non-transferable and expires upon vehicle sale

Frequently Asked Questions
-
Q: Will the AVS 94231 fit my 1995 Chevy K1500 extended cab?
A: Yes. The 94231 fits all 1988 to 1999 Chevrolet C/K extended cab models including the K1500 Cheyenne and Silverado. It is precision-engineered to match the window contour on these trucks for a gap-free fit. -
Q: Does the AVS 94231 fit the Chevy CK regular cab or crew cab?
A: The 94231 is designed for the extended cab body style only. Separate AVS part numbers cover the regular cab CK trucks. Verify your cab style before ordering. -
Q: Will the AVS 94231 fit GMC Sierra and Sierra SLE trucks from this era?
A: Yes. The 94231 fits 1988 to 1999 GMC C1500, C2500, C3500, K1500, K2500, and K3500 extended cab models including Sierra, Sierra SL, Sierra SLE, Sierra SLT, Sierra SLX, and Sierra Special trims. -
Q: Do I need to drill holes to install the AVS 94231?
A: No drilling is required. The 94231 uses pre-applied 3M VHB automotive adhesive tape that bonds directly to the painted door frame above the window glass. Installation typically takes under 30 minutes per window with no tools required. -
Q: Can I run my windows down with the AVS 94231 installed?
A: Yes. Because the 94231 mounts on the outside of the door frame above the window glass, it does not interfere with window operation in any position. This is one of the advantages of outside-mount over in-channel designs. -
Q: Are the AVS 94231 deflectors car-wash safe?
A: Yes, after a 24-hour cure period following installation. The 3M adhesive reaches full strength within 24 hours and the deflectors are rated car-wash safe from that point forward. Avoid automated car washes during the first 24 hours. -
Q: What is the warranty on the AVS 94231?
A: AVS covers the 94231 with a Limited Lifetime Warranty against defects in materials and workmanship. The warranty applies to the original vehicle owner and is non-transferable. It expires if the product is removed from the original vehicle or the vehicle changes ownership. -
Q: Will the smoke tint on the AVS 94231 fade or yellow over time?
A: No. The 94231 is constructed from UV-stabilized impact-resistant acrylic that resists fading and yellowing even with years of direct sun exposure. The smoke finish maintains its appearance through all seasons without cracking or discoloration. -
Q: Can the AVS 94231 be used in an automatic car wash?
A: Yes, once the adhesive has fully cured for 24 hours after installation. The 3M VHB tape on the 94231 has been proven to hold through automated washes, subzero temperatures, and triple-digit summer heat without lifting.
Installation Instructions
- Clean the window frame mounting surface thoroughly with an isopropyl alcohol prep pad and allow to dry completely before installation
- Install at temperatures of 70 degrees F or above for optimal 3M adhesive bond strength
- Dry-fit each AVS 94231 deflector to confirm correct position before removing the tape liner
- Peel back approximately 1 inch of the tape liner on each end, position the deflector along the door frame, and press firmly along the full length
- Gradually peel away the remaining tape liner while pressing the deflector into place. Run a microfiber cloth along the full surface to activate the pressure-sensitive adhesive
- Do not operate windows or wash the vehicle for 24 hours after installation to allow full adhesive cure
- Repeat for all 4 pieces: left front, right front, left rear, right rear
