Rear Progressive Suspension

[RNFWP]

Pulled my shocks as part of a final drive maintenance. One seems to have a slight leak.
A quick look online but I didn't see parts/repair kits. If these go out... will I need to buy new shocks?

When my 440s blew out it was a big
Mess... they rebuilt them for me free
Since Ihad my receipt. They discontinued
440s though, and I don’t think they’d
Even fix them if you paid them now.

If yours are 440s you’ll probably have
To start looking for something else when
They get bad.
