I have progressive 412s and I think one of them is leaking oil. Has anyone ever heard of this happening?

 

Yes, it happens.

 

Will I need to replace them?

 

I have read about leaks from 412's a few different times over the last year here on this forum. It's unfortunate.

 

Just happened to me over the winter, I was trying to figure out where the heck the fluid was coming from and getting on my rear caliper, wheel and swing arm. Come to find out it was my shock ( 412s ) There's a year warranty on em so if you have the receipt and they are less then a year old you can call progressive shocks and get a RMA.... You will have to pay to ship the shocks to them. They rebuild them and send em back. Took about a month
