Welcome I sell mainly RV parts, door, windows,awnings, etc as I have retired from repairing motor homes with a huge shop full of 100's of parts and pieces I would like to offer others. Some items are one of a kind while we may have multiples of others please feel free to get a great deal.


This listing is for 2 pair (4ea) new replacement Gas Struts (you are not getting the toolbox)

4 struts = replacement for BOTH lids

(We also have a 2 strut listing)

Diameter rod = 6mm / tube = 16mm

20 pound force at rest (full extension)

You are bidding / buying  (4ea) gas spring / shock / strut Manufactured by Nitro-Prop Strut and Spring (NP1200-20) this unit is totally self-contained, hermetically-sealed, a hydro pneumatic linear actuator containing pressurized nitrogen gas, which provides the output force.

Note: for best results replace both struts (when 2 struts are used) ... ALWAYS install with rod down (your struts will last much longer ... here's the reason all struts contain a bit of oil / that is what causes the damping effect towards the end of the stroke ... this oil also lubricates the piston, installing the rod down keeps the oil atop the piston!)

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!

The shipping, s a set cost of $15.00 ( USA ONLY)

Thank-you for your interest
