N15 fork dampers

Hi.
Please, how much are the N15 fork dampers longer than Commando one?.
Are the dampers stretched with an extension rod?
Thank you.

hi
Lets make sure we have terminology clear.
Damper body
Damper rod
stanchion (fork) tubes
Damper springs
All components are longer than Commando ones.
My notes state.
The stanchions should be 1 7/8" longer (24 7/8" compared to 23 for Commando) and the damper tubes should be 1" longer.
The damper rods are not stretched with and extension. They were manufactured longer.
Mines together so I cannot take a measurement for the damper rod.
Regards

Hi.
Damper N15 is 28 cm.
Commando is 24 cm.
N15 damper and rod, full out, is 76.
Commando 71.
These are mine measurements.
