progressive 412 11" shock concerns
I finally got my progressive 412 11" shocks and installed them but I have a few questions, o ya I suggest changing shocks with a lift I stripped the bottom bolt while removing one!
1)The chrome dosent seem to be the best quality is anyone having pitting probs or anything with the progressives?
2) It seems like lowering the bike that inch is going to take away a lot of rear end travel im not sure yet since I havent had a chance to ride with them yet.
3) install only took about 15 min
4)the stickers were a bitch to remove even using a heat gun

RE: progressive 412 11" shock concerns
I've been running 412s for over a decade with no pitting at all. If you're over 190 lbs. you'll experience a stiff ride as the travel is limited and you'll be getting pounded on rough roads. Despite this, I still prefer them to the stockers.

RE: progressive 412 11" shock concerns
My experience with Progressives so far is all good.
I have these....
http://www.progressivesuspension.com/440.html
And they stay shiney, and work as advertised.
( But I did NOT try to lower the bike. )
Good point on lowering is made here....

Note ***
Lowering Motorcycles
"...........For example if you lower the motorcycle 1" you will lose 1" of wheel travel. A motorcycle with 4" of wheel travel that is lowered 1" will lose 25% of the ability to absorb bumps. Decreased wheel travel will increase bottoming and decrease ride quality. Lowered shocks will generally have stiffer spring rates and damping to help compensate for the loss of travel. Initial cornering clearances will also be affected and care must be taken in making turns at any speed. Lowering motorcycles that are heavily loaded is not recommended."
So it would depend on what clearence you started with, and that would decide how "Stiff" the ride will be..... and if the effects are acceptable to you.
Anyways.........

RE: progressive 412 11" shock concerns
Before I spent a lot of money on new, shorter shocks for my FXD, I had the stockers cut down to 11.5" just to see how it would ride and corner. The ride suffered a slight amount, but it is still very acceptable. Going down another 1/2 inch is pushing the limits of the shock to do its job. Now that I know that 11.5" is best for the way I ride, I'll get a set of non-HD 11.5" shocks put on this year.
BTW, you didn't post what kind of Dyna you put the 11" shocks on, the Low Riders area already pretty cut down, lowering them much more might be too much, but see how the ride is. As far as Progressive suspension in general, I've read a lot of posts and the quality seems to be pretty high.

RE: progressive 412 11" shock concerns
I took the bike for a 20mile ride this morning to set the bushings and it felt better than the stockers even though I lowered the shocks 1 and 5/8 inches. I feel the ride is very exceptable for the shock height so I must say I am happy and the bike is an FXD.

u are exactly right. i wanted to do it to my l/r but i ride 2-up 50% of time,so i decided against b/c of the bottoming out thing. so instead i got the lepera solo. i would still get the 11.5" but i can't b/c of the harshness it would have when my girl is with me. the lepera however,lowered my s/h 2".and i can ride all day and not have any pain.
