- Two-pack supplies both sides in one purchase
420 mm 250 N gas spring pair
This set contains two black-and-silver gas springs built with plastic and metal components. Each unit measures 420 mm overall length and 18 mm maximum diameter. The piston rod is 160 mm long by 8 mm thick. They are sold new and ready for installation.
Suited to hinged lids
These springs work well on horizontally hinged doors, canopies, tool-box lids or light machine guards where a 250 newton lift force matches the panel weight. They are not intended for heavier hatches that require a higher force rating, nor for vertical-strut applications where the geometry differs from horizontal hinge use.
250 N lift force with 160 mm stroke
The 250 newton rating comfortably holds typical garage cabinet doors, access panels and lightweight hoods through the full 160 mm rod travel. Heavier industrial hatches or full-height vehicle bonnets that exceed this force will not stay open and should use a stronger spring.

Questions about this item
What mounting thread must my lid or door already have for these M8 ball-joint gas springs to fit?
Your lid or door needs M8 threaded mounting points to accept the ball joints on each spring.
Will the 250 N force be too strong for a lighter hatch I want to keep using?
Each spring exerts 250 N, so a lighter hatch may not stay closed or could slam open; verify the hatch weight matches this force rating.
How do I confirm the stroke length is correct after installation?
Measure the extended centre-to-centre distance; it should read 420 mm (16.5 in) when the hatch is fully open.
