And they fit campers, car and truck hood lifts, Rear glass lifts, toppers and more! Fully extended = 26 3/8 inches ... Fully retracted = 16 3/8 inches (center to center of the ball socket) Diameter rod = 10mm / tube = 22mm 250 pound force at rest (full extension) You are bidding on (1) gas spring / shock / strut Manufactured by Columbia Strut (model CS2637-90) this unit is totally self-contained, hermetically-sealed, a hydro pneumatic linear actuator containing pressurized nitrogen gas, which provides the output force. This unit and comes complete with 13mm Steel ball sockets both on the rod and tube ends (if you are in need of mounting brackets see our selection listed in the store) ********This is the OEM gas spring was used on many Prevost, Marathon, Executive. LeMirage, Liberty, Country Coach and more
1. Just measure the extended length of your shock (from the center of the socket to the center of the socket) that's the length (that was easy!)
2. if you do not know the force pressure, and it is not listed on the shock (most times it is encoded in the part number on the shock) you can always do a simple test, IE camper topper lid ... use a scale to measure the force needed to open the door! That will get you really close
3. Shocks can come in the same length and force pressure but different in physical size (rod diameter / tube diameter- 6x15 / 8x18 / 10x22 / 14x28 MM etc) I think of the physical size in terms of ratings ... standard duty (6x15mm) ... heavy duty (8x18) ... extra heavy duty (10x22), and when nothing else will do use the maxi 14x22MM
4. Mounting brackets / studs can be permanent or replaceable the most common are the ball and socket style (10mm or 13MM) then the ring / eye style. Most shocks come with threaded ends to allow for interchangeable configurations. If you have the option I like to use the ball and socket when ever adding a shock as it is much more flexible then the ring / eye style.
Removal TIP: it is very easy to replace most gas springs / shocks/ struts, the most common connection used is the nylon "ball joint socket" to remove your old unit simply insert a "flat" blade screwdriver under the spring clip (you do not have to remove the clip) using the slot provided in the back of the socket, push the screwdriver down just a bit this causes the spring clip to open and it will release the ball end. The new unit now just "pushes" on and snaps in place, that's it you're done!
