If you do not find the size, length or configuration you are in need of please e-mail us as we have most all the gas struts / springs that are / were used by WRV, Alpine Coach, Alpenlite, Marathon, Beaver, Safari, Winnebago, Keystone and more. 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 = 8mm / tube = 18mm
120 pound force at rest (full extension)
You are bidding on (1) gas spring / shock / strut Manufactured by Columbia Strut (model CS2637-120) 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 threaded removable 10mm ball sockets both on the rod and tube ends (if you are in need of mounting brackets see our selection listed in the store)
*****Attention: Alpine Coach, Alpenlite owners as WRV (Western RV) is no longer in business you want to pick up a few items I have listed for spare parts, this unit was used in the ALPINE coach, Alpenlite trailers and some toy haulers. This is a WRV OEM part and requires no modification for installation!
********This gas spring was used on the cargo doors and the storage compartment under the queen size bed in many Alpine and Alpenlite units! OEM UPGRADE UNIT (for heavier beds ' IE custom mattress)
Replacement TIP: There are many brands of gas springs / shocks / struts manufactured today with just about as many names Nitrogen gas, gas, struts, springs, shocks, dampers etc. , some have a part number that is as equally confusing to understand with out a reference guide! If you are looking to add or replace any gas shocks (they all get weak, worn, bent or broken and need to be replaced at some time) it is easier than you think, here are the basics
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!
Thank-you for your interest
