Title: Engine Door Gas Spring Shock
Post by: Tom Dixson on March 03, 2015, 01:40:46 AM
Trying to find replacements engine door shocks for my 2006 Patriot Thunder.  These are the gas/spring loaded shocks that assist in lifting the engine door and then hold it up.  Current shocks are tired and only hold door half open.  I believe they are 150 lbs

Contacted allied rec group and they want $120 per shock, while I seen a lot of shocks $25-30.  Has anyone had experience with locating replacements at a reasonable price?

Tom, the best way is to take the shock off and go to a parts store for an exact replacement.

Or get the numbers off the shock and Google for a place to purchase.   The number will tell the length and capacity for an easy match.  No way they should be $125,

Tom;  Thanks for the response.  My old shocks are Stabilus Lift o Mat 752991 0600N 017/05 A5 and 22 inches fully expanded.  I googled Stabilus and for the life of me can't get anything usable.  Don't know if Stabilus is out of business or a foreign company.  Took old shock to a number of auto parts stores and no one knew how to read the part number as to how many pounds of lift.  Also, found 22" is an unusual size.  Even took the old shock to Quartzite, with hopes I could find a match, but no luck.  At NAPA, they felt they were 75 lbs, as the number started with 75.  Put the new 75 lbs shocks on and the door immediately closed and was extremely heavy, so obviously way to light.  They will special order a heavier shock, but I had hoped to determine the correct strength before I special order.  Allied, although they have the shock in stock would not provide me with any info such as manufacturer or strength weight.  Obviously, knew I planned to price shop.  Haven't given up, but I hope someone on this forum has already solved the problem.

I have found the correct ones using rockauto.com. Go to universal parts and under body parts then go to universal lift support. May not have exact length but the ones with the 10mm ends are what go to all my side doors on the Contessa.

I have bought varying brand but I find genuine Suspa brand to be superior in adequacy of lift through the whole range of travel as well as longevity of usable life. (gas eventually escapes) What I mean about adequacy of lift through the range of travel is not fighting to hard to pull down a lifted door when it is fully up and not fighting too hard to start to lift it when it is fully down. The Suspas seem to have mastered the pressure curves through the whole range of use better than the others.

I found a Stabilus catalog online.

  http://www.stabilus.com/fileadmin/DAM/Brochures/Standard_programme/Standard_programme.pdf

Check page 15 your part number 752991 is there.  Stroke is 250mm (9.8")   Extended length 585mm (23.03") Force 600 N (135 lb)

Using the info Steve Huber posted a GSNI-2400-120 should work.

Good luck

Steve

I started using one GSEL and one GSNI series from SPD on all my PT Bay doors and will do the same on the Marguis doors that are not cantilevering.   The GESL is the same as GSNI but with a lock mechanism that positively keep the lid from unwanted closing.  Might be worth taking a look at.
