✅ Direct Fit Replacement: Engineered to match OEM specifications for thousands of car models (Toyota, Ford, BMW, etc.).
✅ Smooth Lift Assist: Nitrogen-filled cylinder ensures easy opening and prevents the trunk from slamming shut.
✅ All-Weather Durability: QPQ nitride rod and anti-rust coating withstand rain, snow, and road salt (-40°C to +80°C).
Colewell manufactures premium Car Trunk Gas Springs designed to restore the lifting power of aging vehicle tailgates, hatchbacks, and bonnets. Our gas struts are direct replacements for failed OEM parts, providing the same fit and function at a fraction of the dealer price.
For wholesale gas struts buyers and auto parts distributors, we offer a vast catalog covering major car brands. Each strut features high-quality seals and dampening technology to ensure smooth opening and safe holding, even in freezing winters or scorching summers.
| Force Range | 100N - 2500N. Calibrated to match specific vehicle requirements (e.g., SUV liftgates vs. sedan trunks). |
| Material Build | Cylinder: Seamless Steel with black powder coating. Rod: QPQ Nitrided Steel (black) or Hard Chrome (silver) for wear resistance. |
| Sealing System | Automotive Grade: Multi-lip seals and wear-resistant guide bushings ensure zero leakage over 50,000 cycles. |
| Operating Temp | -40℃ to +80℃. Essential for reliable trunk opening in cold winter mornings. |
Our struts come with vehicle-specific end fittings (ball sockets, brackets) pre-installed. No modification or special tools required—just snap off the old one and snap on the new one.
Integrated hydraulic damping slows down the piston at the end of the opening stroke, preventing the trunk from bouncing violently against the hinges.
IATF 16949 Certified. Manufactured under strict automotive quality standards to ensure consistency and reliability for every batch.
• Branding: Laser marking your logo on the cylinder.
• Packaging: Custom retail boxes or bulk packaging for assembly lines.
Rear Liftgate: Supports the heavy rear door of SUVs, hatchbacks, and minivans, ensuring it stays fully open for loading groceries or cargo.
Engine Access: Replaces the manual prop rod, making it easier to check oil or perform maintenance. Heat-resistant seals ensure longevity.
Glass Lift: Supports the independent rear glass on SUVs and pickup truck caps (toppers), requiring precise low-force calibration.
Bed Protection: Assists in lifting heavy fiberglass or hard plastic truck bed covers, keeping gear secure and accessible.
Hydraulic fluid ensures smooth lifting without jerky movements.
Direct-fit connectors mean installation takes only minutes with a screwdriver.
Prevents the heavy tailgate from falling unexpectedly on the user.
QPQ rod finish resists rust and corrosion from road salts and moisture.
We offer custom lengths and pressures for modified vehicles or new designs.
Self-lubricating design ensures long-lasting performance without service.

A: Check the OEM part number on your old strut. If unreadable, measure the extended length and tell us your car model and year.
A: Yes, always. Replacing only one causes uneven loading, which can twist the trunk lid or cause the new strut to fail quickly.
A: Yes, our struts are rated down to -40°C. However, all gas springs naturally lose a little lifting force in extreme cold due to gas contraction.
A: Most trunk struts have high force (e.g., 400N+). You likely cannot compress them by hand. They must be installed on the car to work properly.
