410, 411, 412 servos

[Thomas591]

The previous owner of my 411 S5 installed two new Lockheed servos on my car. I have no comparison, but for me the car brakes well, with the right “feel”.
Unfortunately I can not see any markings on the servos telling me what type it is.

The previous owner of my 408 also installed two servos. For what it's worth, they were from Moss Motors part no. 117-312. They are by Powertune whose part number is RLE72696. I find them adequate but I'd prefer a bit more boost.

Those moss units have a 1.9 : 1 boost ratio. I think the originals on the 410 were LR18503 with boost of 4.5 : 1

I can't find replacements at 4.5 : 1 but have found 4.25, so that is looking like the best option at the moment.

Yes, I really think I will have to fit ones with higher boost sometime soon. What source and part number are the ones you found, please?

LR18230 available from JustJags at about £200 each.

Thank you.

No guarantee that they will fit. Worth checking dimensions before parting with cash.
