✅ Direct Replacement: Fits popular rolling cabinets (Craftsman, Snap-on, Husky) & truck bed boxes.
✅ Heavy Duty Lift: High-pressure nitrogen handles heavy steel lids; prevents accidental dropping.
✅ Workshop Ready: Black Nitride rod & NBR seals resist grease, oil, and grime common in garages.
✅ Soft-Open Action: Controls the lid's upward momentum, preventing it from banging against the back hinge.
Revitalize your workspace with Colewell's Gas Springs for Tool Boxes. Designed as a premium upgrade for worn-out OEM struts on brands like Craftsman, Husky, Snap-on, and Kobalt, these struts restore the smooth lifting action of heavy top lids.
Engineered for the garage environment, our tool box gas springs feature oil-resistant seals and a durable black nitride finish to withstand grease, grime, and daily abuse. Whether for a rolling mechanic's cabinet or an outdoor truck cross-bed box, Colewell ensures your lid stays open securely and closes softly.
| Force Range | 40N - 800N (approx. 10lbs - 180lbs). Common ratings: 45lbs, 60lbs, 80lbs to match standard toolbox lid weights. |
| Material Build | Cylinder: Heavy-gauge Steel with Black Powder Coating. Rod: Black QPQ Nitrided Steel (Harder and more corrosion-resistant than chrome). |
| Sealing Tech | Oil-Resistant NBR Seals: Specifically chosen to prevent degradation from workshop oils, cleaning solvents, and extreme temperatures. |
| Dimensions | Tube Diameter: 15mm / 18mm / 22mm. Length: Customizable to fit compact 26" chests up to massive 72" rolling cabinets. |
Designed with standard 10mm ball sockets or eyelets to perfectly match the mounting points of major toolbox brands. No drilling required for most replacements.
The QPQ black surface treatment not only looks professional but offers superior resistance to scratches and rust compared to standard silver rods.
Prevents the lid from flying open and hitting the wall or back of the truck cab. The strut controls the speed for a smooth, high-quality feel.
Ensures the heavy steel lid stays fully open while you work, eliminating the risk of it slamming down on your fingers or tools.
Top Chest Lids: Supports the heavy top lid of 26", 40", and 50"+ rolling tool chests, ensuring easy one-handed opening.
All-Weather Lift: Fits aluminum cross-bed boxes (like UWS, Better Built). Resistant to rain, snow, and road grime.
NBR seals withstand exposure to engine oil, WD-40, and workshop chemicals.
High-pressure charge lifts commercial-grade steel lids with ease.
Prevents accidental lid drops, protecting mechanic's hands from injury.
Controls upward speed to prevent the lid from banging against walls.
Clip-on ball connectors allow for swapping out old struts in seconds.
Performs reliably in freezing winters (-30°C) and hot summers (+80°C).
Colewell Machinery understands the needs of mechanics and tradespeople. A broken toolbox lid is a safety hazard and an annoyance.
We produce OEM-quality replacement gas springs that meet or exceed the specs of big-brand toolboxes. With fast delivery and precise force calibration, we get your equipment back in working order quickly.
A: Look for a part number on the old strut. If faded, measure the fully extended length (center-to-center of ball studs) and the force (usually printed in Newtons or Lbs).
A: Yes, absolutely. If one has failed, the other is likely weak. Replacing only one can cause the lid to twist or the new strut to wear out prematurely.
A: Yes, our struts feature a QPQ nitride finish and NBR seals, making them highly resistant to rain, snow, and road salts.
A: We don't recommend it. Excessive force can bend the lid or damage the mounting brackets. Stick close to the original force rating.
