Aftermarket convertible hydraulic cylinder rec?
Hi...I need to replace both of the convertible hydraulic cylinders/rams in my 2002 911 Carrera. These are expensive parts, so I wanted to see if anyone had a recommendation for a good quality aftermarket replacement? I'm seeing both Suncoast and TopHydraulics have options online, but I'm not finding any reviews of either. Any help would be greatly appreciated.
Thanks so much-
Robert

Are you sure they are both bad? Explain why you are sure you need them. There are several reason why a top is not working correctly. A replacement battery could be one of the many reasons.

The cylinders are both leaking: 2 years of re-topping the hydraulic fluid, puddles of hydraulic fluid in front of the rear wheels, and the local Porsche shop additionally verified they were both leaking. The question here is not whether they're bad.

My top stopped working properly - can't recall exactly, but I think the top stopped going up, requiring me having to help it along. I went to dealership who looked into it and found one of the cylinders had failed. They advised doing both to prevent an imbalance in the mechanical operation - one would be new, the other old and destined to fail.
After reading up on rennlist.com, the TopHydraulics seemed the best option. I contacted them and discussed. They have ~$500 deposit on the cores to ensure they get the old ones back to recondition for someone else.
Once I had the work done and sent the cores back, they were quick to pay me - no questions at all. In addition, the cylinders are guaranteed for the life of the car. Saved me a substantial amount compared to new ones from the dealership, even with my PCA discount on those...

I would recommend Top Hydraulics also. I replaced both mine (only one was leaking) and Klaus was very helpful with answering questions throughout the process and accommodating me when I pinched one of the lines reinstalling them.

My mechanic noted that both my rams are leaking, so based on this thread, I'm going with TopHydraulics service as well. Can't really go wrong, since the rebuilds uses better components than new, with a warranty for 3 years. So regardless of the cost, the rebuild seems like a better option than just buying new, especially given the cost difference and the fact I don't have to wait for the rebuild to complete, as they ship rebuilt rams out immediately and wait for my core exchange.

I also had leaking cab cylinders on my 99 996. They had bin "rebuilt" by the PO but it was just a DIY seal replacement and the rebuild did not last long. I contacted Cabriolet Hydarulics https://cabriolethydraulics.com/diy-...-instructions/ and have been extremely happy with the service they provided. I sent them my cylinder and the turn around time was less than a week./
Total cost $535.00. They also replaced the o-rings on the hoses and included fluid to fill the pump with.

I now have a 997 cab but the mechanism is the same and replacement very similar. I went with the Cabriolet Hydraulics (CH) for two rebuilt cylinders this time (2019). Took me about an hour to remove the cylinders and about a week to get the replacement cylinders. Pick a time when you can let your car sit for a week.
It took a couple of hours to replace as I was going back and forth to the instructions from CH and a youtube video from another company (showing other aspects of the procedure) and also, had to refill the fluid a couple of times which was a little out of reach on mine.
Things to be aware of:
For attaching the lines to the pump, it's good to have an additional set of hands. Be sure to put a bunch of rags down to absorb any fluid leakage.
Good luck with your install. I figured doing it myself saved me over $2000 in labor costs and parts (by going the CH route).
Overall, I know I could do it faster the second time around, which I hope won't be for another 10 years or so. On a scale of 1 - 10, with 10 being most difficult, I'd rate it as a 5.

Things to be aware of:
- Label all of the wires and connections to make sure you put everything back (there's probably 4-5 electrical connections).
- When you remove the cylinders, note where the drain hoses lie - you have to put these back in the same position
- On the drivers side, be aware of the potentiometer and be careful when replacing the cylinder. The inside bolt fits into the potentiometer, which slides to control the raised and lowered positions. The potentiometer is made of cheap aged plastic and can break.
- Tightening the inner bolts of the cylinder is tricky and may tear up your hands a bit. Lot's of sharp edges in there
- It may be worth looking at removing the rear speakers to allow easier access to the inside bolts. I did this after the fact and it looked like you can save some skin and ensure the potentiometer is properly set on the bolt.
