Gas Springs
by Kenneth from Eads, Tennessee on May 30, 2016
The Attwood Gas Springs were an exact replacement for the OE springs on my Nitro live well lids. If the price, shipping, or fit had been any better, I couldn't have stood it!

Perfect replacement for 340 Sundancer Transom Storage
by John from Rochester, New York on May 12, 2013
This was a perfect fit for the transom storage lid to a 340 Sundancer. Took me 5 minutes to take out the old one and popped in this new one. Works great. With that price, I opted not to go the stainless route but I'm in a fresh water environment. Very reasonable shipping and quickly processed. I've ordered other things again already from iboats

Just what the doctor ordered!!
by Andy from Terra Bella, California on February 07, 2012
I've had problems with my 12" springs on my 2005 Mobius LSV since I bought it. The deck lids would come crashing down on your head with any little movement or wind blowing. It came stock with 30 lb springs. These were the perfect fix. Went up 10 lbs and everything is perfect now.

Is the Attwood Springlift SL35-40-5 interchangeable with SL35-40-1? I have the SL35-40-1 that I need to replace.?
Yes it does. The "-1" and "-5" only indicates packaging. It is the same model and PSI.

Atwood springLift gas shock SL -28-70 6271lv 031in 034/15 c 5 I need two of them?
We do not list that item as of right now. We can look into a special order. Just contact us at the number at the top of the page.

How do you measure the shock I need? Lid doesn't currently have one?
You measure center of stud to center of stud to get extended and compressed lengths. So it will depend on your hatch or lid, but measure with lid open where you would mount when it is opened. Then measure for the compressed length.

Does the SL50 fit this gas spring?
The SL35 is a gas spring with a 10mm socket. The SL50 bracket has a 10mm ball, so they will work with each other. The gas spring will not work with the SL50 blade. Be sure you select a SL50 bracket with a 10mm ball.
