Dave Pumphrey Posted May 9, 2020 Share Posted May 9, 2020 Anyone replace the gas shock lift cylinders on a 2000 Dynasty 38 foot? Mine have gotten weak, & don't hold hatch up very well. There are no visible markings to be seen. I took some measurements, 26 & 1/4" extended, (center of ball to center of ball), with unit removed. 9 & 3/4 travel. The balls they go on are 10MM. The unknown item is the weight they support. They must be pretty strong, because with 1 removed, it takes a lot to pick up the hatch. Thank You Dave P Link to comment Share on other sites More sharing options...
Dr4Film Posted May 9, 2020 Share Posted May 9, 2020 I believe mine our 150 lb gas springs. Link to comment Share on other sites More sharing options...
eddie4ne Posted May 9, 2020 Share Posted May 9, 2020 This is what we bought as a replacement for the missing strut that had also had a broken stud bc of rubbing against the air filter vent pipe. We are replacing all three. Sharon 2002 Windsor Link to comment Share on other sites More sharing options...
erperry_44 Posted May 9, 2020 Share Posted May 9, 2020 I replaced mine last year. 100#. Got them on Amazon. Link to comment Share on other sites More sharing options...
eddie4ne Posted May 9, 2020 Share Posted May 9, 2020 I agree that 150# might be overkill but that is what was on the other side. HINDSIGHT! We ordered 2, a pair and a spare idea, but ended up using the second on the bed- way overkill! Bothe areas had been used for years with only one prop!

eddie4ne Posted May 10, 2020 Share Posted May 10, 2020 We have not installed yet but we are planning to cut it in half. I think that we could third it but do want to impinge the hinges. We are planning to reuse the clamps that are currently in use. Link to comment Share on other sites More sharing options...

So you used 1 of the new 150# lifts on one side, & left the original on the other? I am thinking of trying a pair of 100#. Link to comment Share on other sites More sharing options...

Paul A. Posted May 11, 2020 Share Posted May 11, 2020 (edited) This is an old post i had filed away, posted by another member. In March I requested help with determining the pounds for a "2004" Dynasty engine compartment door but failed to get the information needed, so did my own research and will pass this along for anyone interested. The struts were ordered through Suspa for less monies than some of the other suggested sites. The struts were made by the following: "2004: Dynasty--Part #C16-12181--150lbs each Suspa Inc (esupport@suspa-inc.net)3970 Roger B Chaffee Mem Dr SeGrand Rapids, MI 49548616-241-4200 That flexible ducting you are considering replacing causes a huge amount of "air friction" That's why truckers use rubber fittings and aluminum tubing for the air intake . Here is a link, https://www.intakehoses.com/ to a great site with all the items you need to convert to that. Room may be an issue for you. I did it on a 07 Executive with a ISX 525 Cummins.

Did you use the whole piece, or cut it down? Installed the air intake today. We ended up cutting the 10' in half. It is on but it was a booger to get on the flange of the air filter and upper as well. The diameter is 7"OD and the flanges are 7 ID. The aluminum is quite thin and wanted to rip in the coils. As a reinforcement at both ends we reinforced with gorilla glue duck tape (that is some strong stuff). Link to comment Share on other sites More sharing options...

If they prove to not be strong enough, I will go with these. Thanks for the input, I will post results when I receive them next week. 8 hours ago, eddie4ne said: Installed the air intake today.

Dr4Film Posted May 14, 2020 Share Posted May 14, 2020 I would not recommend using that thin aluminum ducting for air intake. I replaced mine with the very same material it came with from the factory. 7 inch ID RFH Hose/Ducting Black Thermoplastic Rubber Wire Helix 1 Link to comment Share on other sites More sharing options...
