Lift Struts, gas shock(s) The smaller length red ones are 37 cm. and are ideal for small car engine hoods or perfect for a lid on a utility or toy box or what have you.. The longer one at 57 cm was ordered for my Honda wagon tailgate (I didn't need it) but also is ideal to hold up any lid. Both lengths of lift shocks will support around 60 lbs. They are all new and not used. Asking $10 for the long one and $35 for the short pair. There is a selection of mounting hardware. Depending on your project you may require a bracket.
