Default How long should shocks last?

I was wondering what you think a reasonable expectation is for shocks on a Heritage Softail Classic, in miles. I've hit 31K on my '06. Frankly, I haven't noticed much deterioration (I ride solo exclusively), but it might be one of those things that you really don't notice until one day you hit a bump and find yourself sitting on the frame. I've been thinking about replacing the original shocks with a set of Progressive 422's. Would I really see an immediate difference?

Probably biggest difference you'll notice is your wallet will feel much lighter.

Personally, I think the Heritage is one of the smoothest riding Harley's made and see no need to improve on it.

I think you're probably right on all counts

They wouldn't happen to be Chubby 518s on your Heritage?

They would indeed. Good eye. Completely eliminated that pain between the shoulder blades, even on 6-7 hour days.

The difference between the stock shocks and 422s is night and day. The rear suspension on a Heritage is no different from that of a Night Train, and the 422s made my 'Train far more comfortable.

I hear what you're saying, and I wonder if you could be a little more specific about just how the difference was "night and day". Do you ride mostly solo or two-up?

Both. When I went to the 18" rear wheel, the back of the bike looked like a YZ125, and the wife was having difficulty getting on the back. I bought the Progressives specifically to lower the back end. I'm now sitting 1-1/2" lower than stock.

What I found after I figured out my preload settings was that either solo or 2-up, the back of the bike didn't hammer me nearly as much as it did with the stock shocks. It's still a Softail with all the built-in limitations of the form-over-function rear suspension, but the 422s do a much better job of isolating the tire and swingarm, and keeping the bike planted. I can really notice it in the corners going over road imperfections. I can feel the rear suspension working while the bike stays stable.

On a couple of long solo trips, I've move the ride height back up to stock, and with the extra travel the bike becomes about as comfortable as a Softie is going to get.

The key with them (and the stock Showas for that matter) is correctly setting your preload. Yes it's a pain in the nuts to get down on hands and knees and adjust the shocks before every ride (assuming you're alternating solo and 2-up), but the payoff is well worth it.

Great, thanks for the elaboration. Since I only ride solo, presumably I would only have to set the preload once and then forget about it. It is hard to imagine that the 422's wouldn't have a noticeable effect on the ride quality, when properly adjusted.
