No Part Number? No Problem!
Three Steps to a New Gas Spring.

Most people find a new gas spring by using the part number of the spring that they are replacing. But, if your old spring never had a part number, or if the number has worn off, a little information about your old spring will work almost as quickly.

 No Spring to Measure?

If you are not replacing an old spring, but are, say, working on an entirely new project, answering the questions below based on your plans for the new application can still be pretty helpful - or you may just prefer to see a list of all the Attwood SpringLift gas springs that are available and plan your project accordingly.

Three to a Match.

Making a few simple observations about your old gas springs will tell you just about everything you will need to know about your new Attwood gas springs. What you will need is:

1. Get End Type

2. Measure Spring Length

3. Measure Rod Diameter

There is more detail about each of these three items both below and in the picture on the right.

Once you have figured out what you've got now, we can go ahead with finding out what you'll need to replace it.

1. Begin at the End

The majority of gas springs have a "socket" type of connection end similar to those shown in the top picture on the right. You will want to ascertain that your old spring has this type of connection end as well.

The alternative connection end is the "blade". Attwood SpringLift builds - and we offer - some of these springs, but the variety of sizes available with a "blade" connection is fairly limited.

If you find that you have a "blade" connection end on your old spring, don't panic! You may well find that we have a comparable sized replacement. And, if you don't, it's simple to change to your gas spring brackets to "socket" style to greatly increase the number of springs that are available to you. And, if you have to make this change, we have a full selection of these Attwood SpringLift gas spring brackets for you.

2. Measure the Extended Spring

The second thing that you will need to know is the length of your old gas spring.

As shown in the illustration, make this measurement from the center of one of its connector end to the center of the other when the spring is fully extended.

3. Determine the Rod Diameter

The last piece to the gas spring selection puzzle is the rod size of your old gas spring. By rod, we mean the metal shaft that moves in and out of the gas spring body.

Most gas springs rods are measured in millimeters. The three translations to inches in the picture are approximate, but if you get fairly close, your project shouldn't suffer in the least.

On your marks...

While gathering all of the above info, a lot of folks discover that their old gas spring has a part number after all. If you have just joined this ignominious club, you may want to "search by part number" approach first.

If not, and you have the connection end type, extended length, and rod diameter of your old spring, you are ready to pick your new Attwood SpringLift gas springs.
