Progressive shocks

One of my thirty year old S&W shocks is leaking so it's time for fresh ones

I am probably going with Progressive 12 series gas shocks with the heavy duty black springs.
Unless you guys talk me out of it.

I think They're around 260 bucks delivered from Z1

Do they last ?
Are they better than oil?
How can you tell if one goes bad, with the oil shocks it's obvious . :whistle:
Is there any other good choices in that price range?
Thanks,

JD

I've been running them on my bike for the last couple of years and have no complaints.

I also have the 12 series on my bike. I have both the heavy duty springs and the standard. The heavy are great for touring with bags and gear loaded up. The standards are better for normal load, of course. Once you change them, you will see they are much better than your old shocks. Its to bad they don't have a rebound or dampening adjustment, but then the price would be higher also. You can definitely spend a lot of bucks on shocks and get the best if you desire. The Progressives are good for the money.
If you do a search there are a few threads on the Progressives, including one I started a couple of summers ago.

I put progressive (brand) rear gas shocks on my 750 twin about 5 years back and I love them. They are so much better than stock. I think I got them at Z1 if I remember correctly (?) But the gas shocks are the cat's pajamas.

I put a set of Progressives, heavy duty springs, on an Intruder 1400 I once owned. Although better than stock, they were less compliant than expected, the springs should have been even firmer for two-up riding, and rebound damping was much to soft. Not a bad product, but a pair of adjustable Ikons are significantly better in my experience.

They better be good, the Ikons, for 3X the $$$$!

I have S&W (Monroe) shocks on one bike, and Progressive Shocks on another. I think I read Progressive bought out S&W, but my memory is hazy on that. The two brands look very similar, so much so I could see both products coming from the same factory.

They also ride very similarly. If you like the S&W, then you will probably like the Progressive. You may even be able to swap the springs over from the S&W to the 12 series Progressive and save some money.

I had a set of S&W shocks on my KZ650 for years and they worked great; I believe Progressive did buy them out. Ed

The Set I saw looked very similar to my S&W's only they're gas filled
I normally go for upgraded products but if these perform as well as the S&W's
and are a third the cost it would be prudent in my case to put the money somewhere else.

I'm not racing around any more , mostly riding 2 up with a sissy bar bag full of Mommas stuff.
Somewhere around 350 lbs. fully packed :blush:

Thank you everybody,looks like I'm going with Progressive's.
