When prices are kept secretive thats usually not a good sign.
Yah super secret pricing. He's got a lot of time into a bit of a lower volume selling part so I'm not blaming anyone. It costs what it costs. I know the Pspeed guys are at around $800.
Spent some time building the taller 997TT CAB wing cylinder cartridges.
Nice work, Kevin. Those look terrific. Your stainless cylinders are beautiful and are likely to outlast the car.
In 2018, I managed to make a pair of serviceable cylinders from scratch for my 997 using a small hobby lathe -- I don't remember now how much time I spent, but it was a lot. I didn't have the tools to ream a smooth cylinder bore, so I bought brass tubing that matched the factory dimension and silver soldered machined fittings onto the tubing that allows for servicing the o-rings. I also didn't want to do internal threading, so I ended up using 3 cross-drilled set screws that recess into a relief groove on a removable part.
Here's a picture of my work. I'm not advertising or selling -- this was done all for the learning/challenge -- it's not my business. I'm happy to offer thoughts to others on what I did, but this is really not DIY stuff unless you've got access to a lathe and know how to use it. Sorry, no pictures of individual pieces, and I'm not about to take it all apart again...
Pricing depends on what each individual has for damaged or missing components. From a single hydraulic cylinder ram assy to a full rebuild of the hydraulic pump, hydraulic lines and two hydraulic cylinder ram assy.
Recent examples have new 996TT owners finding out that there new 996TT have fixed rear wings. Only to find out that they don't have a hydraulic pump, and/or hydraulic lines. This also includes finding missing or cut electrical harness and failed limit switches.
However, I will say that Retail pricing for a rebuilt 996TT wing cylinder RAM assy is $795.00 This price requires the owner to send me his wing cylinder RAM assy in for rebuild.
On top of that, Car dealers, and Porsche dealers want complete working hydraulic wing assemblies. Plug and play Exchanged.
My new 996TT and 997TT hydraulic wing cylinders RAM assemblies are unique. We now have a "New" redesigned cartridge that will allow VITON oring replacement.
I can now "hone" the bore to clean up any scoring from alkaline buildup (from high detergent car washing). I even have oversized piston packs if I have to oversize the bore.
Ultimate Motorwerks 996TT and 997TT wing cylinder RAM assemblies are available for owners and Automotive sales and repair centers that want to keep the factory system.
I have a driver side spoiler that doesn't extend all the way either automatically or manually. It will retract both ways but only extends about an inch while the passenger side extends full length. There is no apparent leak and no noise. The durametric doesn't show any fault codes. Would this be indicative of a microswitch or hydraulic issue?

Probably low on Pentosin PS fluid. That side has no microswitches (unlike the Carrera GT) so the computer doesn't know it is malfunctioning. There are methods to top off the hydraulics and bleed, including one guy that recommends removing the back lid altogether.
I would disconnect your two wiring connectors at the electric pump motor. This is done to prevent the drive block damage internally.
When you have time, you can empty, fill and bleed the wing hydraulic assy. Use Pentosin and 30% by volume Lucus Power Steering stop leak. (Don't use more than that)
For minor leaks this will cure flat spotted orings. I have new wing cylinder ram assy available..
Maybe a bit premature to celebrate. When I put the cover over the micro switches it seemed to trigger the warning. So I left off the cover off (is this a good idea due engine heat?) and the warning stayed off. Went for a short drive and the spoiler worked up and down both manually and automatically. A few seconds after first spoiler deployment the warning came on but the spoiler still operated. Both micro switches seemed to be still seated after the drive although the rear switch seemed the least solid. Any ideas? Is this a microswitch issue to be replaced?
Thanks
If you have not bled the system good enough, you can have issues. The upper microswitch might not trip or hangs. The chrome plated cylinder has notches that trip the "sail switch" Upper and lower...
Make sure that your cylinders are reaching the max height and do not sag.
Did you remove the microswitches during the drain, refill and bleed process? How many times did you cycle the pump? Did you measure the extension "max height"
Rarely do I see microswitches fail, usually they suffer handling or collision damage. If you bend the sail switch>> you will have problems.
