I recently purchased a Valk with Prog shocks #4233. Anybody know which shocks these are? 412/440 HDs??
I'm not sure where you're reading the number from.
I have 13 440 shocks with the HD spring. The spring says on it:
03-1318
140/200
When I google "progressive shocks 4233" I get hits on 412 and 430 and 444,
I don't know what 4233 means.
When I google "progressive shocks 1318" the first hit is this
PDF spec page from Progressive:
http://www.progressivesuspension.com/pdfs/7100-105.pdf4233 is listed on the spec sheet several times, maybe you can make
sense of it...
