Manual shows 63-70 ft lb for my 18. Need to go recheck mine now since I followed the instructions that came with my Ohlins
Did your Ohlins come with new mounting hardware, ie, bolts, flat washers, lock washers? Or was OE harware used? Were lockwashers present in the factory configuration?

Only large spacers came with them that I can remember and no lock washers. Reuse factory bolts and a flat washer.

My HD 772 Ohlins came with only thick washers, (4) per shock, mounting instructions say to install same as original shocks. Ohlins provided no torque spec in my mounting instructions. I torque them to 65 ftlbs.
2016 shock hardware, # 3 is a lockwasher.
2017, and up shock hardware, flat washer (#2) only.
In my opinion, this would explain the torque increase stated in the 17, and later FSM.
The torque spec is what is required for the application, not the bolt.
This is not entirely correct. The torque spec is what is required for the application, and that application takes into account the bolt/stud as well as what the bolt/stud is retaining... ...grade, length, etc. By torqueing a bolt you are in fact doing a controlled stretch of the bolt(torque spec) in order to maintain a seal, keep a shock on, keep a wheel on, etc. There are several diesel engine manufacturers that specify that you should replace the head bolts for instance rather than reuse them because they in fact have been stretched. It's all about the stretch of the bolt or stud in order to maintain a specified torque. Over torqueing does one of two things. You will either strip threads or stretch the bolt /stud to a point it can't maintain torque and keep things tight.
