Replaced with same Manf., PN., then could not get the cover in the air.
One old strut was wasted and the new pair were less than useless. Returned to the old one that was good and now opening the cover is possible.
I'm wondering, if for what ever reason I've got new struts that are not up to the spec of the older strut (it took four of use to put it back in place)??
Bright Idea=use an S tie-down sling over the top of the strut for a pull down for the installation, two to hold up the hatch and someone on the roof to pop the strut on the pin (?) What a fire-drill. pc
My cover gas springs are getting weak and I was hoping there was an easy way to change them. I replaced those on the large bay door on the pass. side and had a fit with it by myself. Hoping someone knows an easy way to change the back springs. Also, did you get your springs from FOT?
What pound rating did you order. Many times, if a gas spring manufacturer does not have the correct pressure spring in stock, they will take an existing spring and "pump it up" to the correct PSI. What is printed on the strut may or may not reflect actual force.
Tell us what coach you have and perhaps we can tell you what springs DO work. I now what works on the 1993 U240:
Attwood gas springs: 4 basement doors: SL-34-40. Bed: SL25-170
Irwin Quick-Grip or pipe clamp
Spring Lift on Outside Access Doors (http://www.foreforums.com/index.php?topic=15674.msg96653#msg96653)
We had Extreme's Rance change our rear engine door to a light weight hinged door. Dave M also did the mod and now door that is not a back breaker safety risk. Doors are about a foot shorter so it can easily lift over anything hitched up at the moment.
95' U320C SE.
Funny you should ask this. Have the same coach. I was looking at mine yesterday as they are getting weak. Mine are Spring Lift 25-30.
Here is a source:
Item # SL-25-30, Gas Spring On Moore Industrial Hardware (http://catalog.mooreindhardware.com/item/door-checks-gas-springs/gas-spring/sl-25-30)
I have not checked for lowest price yet but Foretravel are quite reasonable and you will get the correct ones.

Correct; That is the strut pair I went with. The SL 25-30 is a 60psi unit.
In my instance (for whatever reason) they are not doing the job.
I'm going to return them and go with the 90psi version and locate a ratchet strap. pc
As I posted above, I used two 170 PSI struts for the bed lift on U240.
In case anyone is interested, I ended up purchasing new generator door struts from Harco for $10 each (20"/ 150psi) after FOT sent me struts that were too long (26"/150psi).

They seem to be the same quality as the other brands and quite cheap, as long as you know the length and pressure.
