Specifications
- Originals were manufactured by Stabilus Bloc-O-Lift or Gas Springs Corp Easy Lift
- M10x1 metric thread (~0.39 inch diameter)
- Adapter P/N MC37902-06 also available (threads on end of the Gas Spring Style MC587-404)
Replacement Selection
Aircraft make, model and serial number are not sufficient to ensure the correct replacement spring as many aircraft may have been originally equipped with either one or retrofitted with a conversion kit. If the spring you are replacing is marked with a brand name (e.g. P. L. Porter or Stabilus) the correct replacement is readily identified. The coil spring/hydraulic style are also identifiable by a 1-1/4" diameter visible coil spring. The thread may also be measured to verify the correct identification.

Reviews
I ordered the MC587-404 gas seat spring for the copilot seat in my 1977 Piper Turbo Arrow III. I had previously replaced the pilot seat spring. The unit works great. Total time to remove the seat, replace the seat spring and reinstall the seat was about 30 minutes. Great product.

These we an exact fit for the original Bloc-O-Lift springs in my 1980 PA32 Saratoga. It took me less than two hours to replace the springs on the pilot and co-pilot seats.

Easy install and works great on our PA-32 Cherokee 6 300
All went well, thanks.
I would highly recommend this Mc Farlane MC587-404. Its a direct replacement for Piper P/N: 587-404. I replaced this Gas Seat Spring on my 1981 PA32R-301 SP Saratoga. 3 bolts, very easy installation. It was an exact replacement. Works great!
Very fast delivery. Product was the exact replacement part required. Easy installation
Product was easily found and ordered. Shipped and received rite away. Installed in minutes with no problems. Air Craft Spruce is always on the ball .
Purchased to replace a non-working seat height shock in my 1978 Archer II. I’m a short guy and need the full seat height to see over the panel. As a new aircraft owner I looked into whether this was something I could do myself and was glad to find that it was fully legal to perform according to Part 43 preventative maintenance. The shock even has a nice FAA-PMA sticker in case anyone comes knocking on my wing asking about it. Installation took about 20 minutes to remove the seat, and pull it out of the plane. Remove the bolts holding in the original shock and replace with the new one. FYI, my plane already included the adapter block from years ago to replace the original spring height adjuster and this shock simply screwed into it. Now I have a perfectly working seat height adjuster that lets me see over the panel for increased traffic avoidance. It may be listed as a cosmetic repair but I certainly feel a lot safer now.
nice quality and it seems to work just like the original did 30 years ago. Was Easy to install in my Piper Archer
