Default Progressive Monotube Install Question

Wife bought me Progressive Monotube shocks (standard height) for my birthday and I'm trying to get all my ducks in a row prior to installing. I'm very comfortable wrenching myself, have the service manual, and have no concerns. Things I've identified so far is that I will need a 1 3/8" socket or wrench for the caps and a long 6MM allen wrench for the bolts.

My bike is a 2017 Heritage Softail Classic and has 10k miles on it...so still fairly new.

While watching youtube videos and pre-reading the installation instructions, I noticed no one replaced the fork seals when doing this install. With my bike being as new as it is, is there any point to ripping the entire fork apart and replacing everything? Or, can I just get by with dropping out the spring and installing the cartridge? I'm inclined to do the latter...drop the spring and install the cartridge and reassemble.

Any input would be greatly appreciated.

Thank you.

V/R
Dale

You will need to remove each fork tube from the bike to do this. Did mine two winters ago and very happy with them still. It is all pretty straight forward. The only nail biting point I had was removing the retaining cap on the first tube, as I didn't know how much spring pressure was under there. Was not bad at all. Second tube was a breeze. I did replace seals, but that was because I sprung for the chrome lowers kit. Happy I did.

Seals are cheap, leaks are a pain.

YMMV,

Most people have leaky fork seals then decide to upgrade since they are taking them apart anyways. Myself on a bike that new, if they are not leaking, dont change them. I installed 2 monotube kits so far. The first one I removed the tubes for, the second one I didnt. Very easy to install, just follow the instructions on the fork oil amount. With the monotubes you use alot less oil.

Thanks for the help/advice. Since I didn't have to take the forks completely apart (just remove the innards) I didn't replace the seals. Got everything back together and man does she ride great! Having Progressive 422 HD with RAP and Progressive monotubes in the forks the bike just rides and responds soooo much better. No leaks, everything is groovy
