rear spring rate confusion
No.
"Rebound" is short for "rebound damping."
Rebound damping is how the extension stroke (on most bikes) of the shock is controlled. Walk around to the back of your bike and push down (lean) hard on the rear. The back end will bounce and come back up. A good ballpark setting for rebound damping is for you to be able to say quickly "one-thousand-one." Often, stock shocks will rise more quickly (sometimes much more quickly) than this -- because they don't have enough rebound damping. A stiffer spring exacerbates this, because it pushes harder on the shock to extend itself.

So what your saying is the 500 560 has a lot of rebound????????????? Rebound
being the force that pushes the seat back up after it's (the shock) been
compressed??????????

rear spring rate confusion
FaQ says: For reference, the stock spring is 10" long and 300 lbs/inch.
Replacement manufacturers are:
and it says this about eshock : Eshocks sells springs, and
makes a 9" spring that will fit the KLR shock. If you're lighter, you might
like this spring as you can get a better preload adjustment.
My question is for those using eshock springs are you using a spring
that is 1" shorter than stock and does it bring down the ride height or have
some other affect???
On the eshock website they only go up to 9" with a inside dia. of 2.25.
Just trying to get all this info straight before I order a spring.
THANKS FOR ALL HELP!!!!!!!!!!!!!!!!!!!!!!!

Keep reading, further down it says: What are the stats on the stock spring? The stock spring is about 56mm/2.2" ID, 254mm/10" long, and the spring rate has been measured at 5.3 kg/300 lb. NOTE: Although the stock spring is 10" long, the shock appears to be built for a 9" spring. That is, installing the stock 10" spring puts an inch of preload on it, which is quite a bit. The consensus is that you are better off with a stiffer, shorter spring. A rate of 450 lbs/inch seems to be ballpark for riders of 180-200 lbs, and 500 or 550 for heavier riders. However, you might want to consult a suspension specialist (or the list) for suggestions on your specific weight and riding style. The proper diameter is 2.25". So as I understand it, the 9" spring is long enough for the shock & that's what everybody buys.

rear spring rate confusion
For anyone who's interested in my rear spring replacement. This is my
first experience with suspensions mods, so I am no expert. These are
just my observations:
Originally had 1" static, 4" loaded sag with stock 300lb spring,
wanted ~1" static, ~3" loaded sag. Figured (4-1)/(3-1)*300=450 would
be the ideal spring rate. Exact figures came out closer to 400, but I
went with 450 to be safe (list recommendations for my weight are often
500-550lbs), and because the progressiveness of the unitrak would tend
to make the calculation come out low.
I got the Hypercoil spring (9x2.25,450lb) from eshocks day a few days
ago. Bought a $10
harbor freight spring compressor to install it. Originally, I was
going to change the oil, but according to someone at Precision
Suspension in El Cajon CA, you have to dis-assemble the shock to
replace the oil. I figured I can try the spring out pretty easily, and
if there's not enough damping, I can pay someone to rebuild the thing
($100+, not having a shop sucks).
The Harbor Freight spring comp. was on sale $7.99. But - it didn't
fit. After looking at it for a while, I took a file and ground about
1/2" of material off two of the hooks. I was able to use it after
that, and it seemed safe enough to me (if you do the same and hurt
yourself, don't blame me
.
Taking the shock off the bike was pretty easy. Take off the unitrak
links at the rear end only, unbolt the top and bottom of the shock,
and drop it out. Remember which side the rebound clicker and the
preload adjuster are on, though... I ended up putting mine back
together with the clicker on the chain side by accident.
My shock is only a year old, and the damper seemed to be in good shape
- no leaks, compressed slowly, re-extended by itself slowly.
The new spring is about an inch shorter than stock, has slightly
greater I.D., and thicker wire. It required about 1/2 inch of
compression to get it on, and that was easy to do with the spring
compressor. The shock assembly is easy to put back in the bike (except
that I put the clicker on the wrong side).
Riding observations so far (on-road, ~245 lbs rider w/gear):
Spring:1, Rebound:2 - ride height too low, bottomed out on medium
sized pot hole, seriously underdamped
Spring:5, Rebound:4 - shock nearly topped out (only ~1/2 inch free
sag), also very stiff (probably overdamped, possibly made more
uncomfortable by being topped out).
Spring:4, Rebound:3 - roughtly 1" free sag, 3" total sag (just what I
was looking for!), still seems a little overdamped, will have to ride
some more to see.
The difference from stock is not as dramatic as I was expecting. But
the worst problem with the stock was the rear end would squat down in
curves, and the new spring seems to have fixed that. The rear end is
more solid when it needs to be.
Some thoughts:
It doesn't seem like I will have underdamping problems, the stock
damper seems ok for on-road riding (with this 450lb spring, at least).
The shorter spring is forcing me to use up most of my preload... maybe
a 1/4 to 1/2 inch spring spacer would help so that I would have some
preload left when heavily loaded?
Slightly higher rear ride height and stiffer rear spring makes the
front end squirrelyness more noticeable... I wonder if progressive
fork springs would help? I already have 15W fork oil.

Dirk, What's the model number ... please? snip > > Slightly higher rear ride height and stiffer rear spring makes the > front end squirrelyness more noticeable... I wonder if progressive > fork springs would help? I installed the progressive springs and cartridge emulators up front and have yet to do anything to the rear. I really didn't realize how bad the rear was until I improved the front. So I would imagine the same goes for you. Just visa-versa. Thanks for the report. I've often contemplated doing the same but it doesn't seem right to go to a stiffer spring without increasing rebound dampening. Maybe going from 10" to 9" compensates? Did you compare the outside diameter of the eshocks spring to the stock? There doesn't appear to be a whole lot of room in there. Does it look like the spring could ever contact the swingarm? I sure wish there were more options ;
