Question regarding Progressive Suspension 412 rear shock bushing dimensions


 

I'd searched the forum for information regarding Progressive Suspension 412 shocks for the W650 but I couldn't find any mention of problems with the size of the bushings they come with.?

I was thinking I might be able to use the bushings off the stock shocks, but there's a flange on the Progressive shocks that make it look to me as though they can't be removed without destroying them, and the flange also makes it impossible to see the inner dimension of the eyes the bushings go into. I don't want to cut them off to find the stock bushing don't fit in case I need to return them for a correct size.?

I've put in a request from the shop I bought them from, which guaranteed they'd fit, but I figure I might get a quicker answer here about our particular bike's specs.?

Have you tried contacting Progressive Suspension to ask the question ???? I gave them a call years ago about another fitment problem on a different bike and they willingly gave me the information over the phone.

I used pvc pipe, my springs came with directions of how to determine length. Washer on top of spring and top of spacer as I recall

I first contacted the merchant who sold them to me but I'll give Progressive a call Monday morning.?

This is for the rear shocks.? I installed Progressive fork springs last year with no problems.??


 

Update: Turns out the label on the box was incorrect, they'd sent me shocks for a Harley. The fitment notes were tucked inside the warranty so I missed them, but a call to Progressive told me what the numbers for the correct set of adapters should have been. ?

Unfortunately both Progressive and PartsGiant, the merchant from which I'd bought them, were out of stock on the 412-4205C shocks. I'm going to get a refund. So I'm trying yet another online shop, Speed Addicts.
