Progressive 412-4045

I have read in some places that any 412 is fine, and I have read in others that you need certain models, or maybe it is just that they are suggesting certain models. I also read you dont want them to be below below 11.5". So my question is would Progressive 412-4045 work on a 86 VN750? Link Below.

Sorry if this is an obvious question.

But I have just read conflicting things, and am hoping someone could help me out before I put up the money for a pair. I searched the site for any info on them, but could not find anyone using that model number.

Thanks again!

All I can tell you is that Progressive 412, 11.5 inches, standard duty works great on our bikes. Standard duty is 250 pound load. Heavy duty is 300 pound load. I think the 412- 4045 is a Harley number.

Stock shock length is 12.5 inches..

You need to find one for metric bikes...the Harley bushings don't fit the same if I remmber right.

A quick call to Progressive or a search on their website will give you the right part number.

You can also pick spring weight (important if youre either real light or real heavy)

That's correct, but if you want to lower the bike a little you can go to 11.5 The part number for the standard Progressive shock 12.5 inches for the VN750 is 412-4206C

Thanks guys!

Is it possible to mill out the bushings on the HD shocks? Or I guess is it safe to do so?

I understand I may have to lower the front forks in the process, and may have to ride it a bit stiffer to keep it from bottoming out. I am not too heavy, not too light either though haha (5'10" 210lbs) no plus size ladies and I should be fine I think. haha

Thanks I really appreciate the feed back. Between that and the info that is on here it is taking a lot of the guess work out of this.

Was wondering though. Like I said I am about 205, 210 (idk somewhere over 200 haha) are the standard shocks a good way to go? Or should I pick up a heavy duty pair?

Any input would be appreciated. I know that this is more of a personal preference.

Do you plan on having a passenger? Adding luggage or a tail case? Live in pothole city?

If no to all the above, you likely do not need "heavy duty" shocks.
