I have looked everywhere and can't find stock length. I want to put on progressive 412 but need the stock length.

which sportster?
My wife's had 13 inch shocks, but they were too tall so I got a set of 12 inch from a friend that he took off of his sportster. Burly makes some slammer shocks that are only 10.5 inches

Go to your bike, take a tape measure with you and measure your shocks.
center of mounting bolt to center of mounting bolt, it really isnt that hard to do

Are different Model Sportsters with different length shocks .. The Longer the shock the more travel for comfort although progressive recommends not going over 1 inch away from stock length which can be measured as stated above ..

Well it's a xl1200c. the shocks measure 11 1/2 but who's to say they're stock shocks? It a 2005 so they could be replacements. Anyway I just ordered Progressive 412 shocks 12" long.

R's got 13.5"
I thought C's had 12.5"
Low models have 11.5"
just call a dealer and ask.
Correct. Lows also had shorter front fork springs.

Now the XLS-models...........:drool

I ordered the 12" and after noticed that the stock length was 11 1/2" The shocks range from 11" to 13 1/2"
How much would 1/2" longer affect the ride? Should I send them back and get 11 1/2? They have already shipped but haven't received them yet.

11.5" will give the bike a tad lower stance. You'll probably like it more then the 12". The shock will have about 3/8" less travel. Make sure the tire clears the hardware and wiring as it will sit deeper into the fender.

You're saying the stock 11 1/2 will sit deeper and have less travel? Will the bike sit 1/2" higher in the rear with 12"? Why do they offer shocks up to 13 1/2"??:whoa

I got this from DK review:

Save your back from jarring bumps and pot holes
Date: June 23, 2010
I bought these in the 13 inch length for my 92 XLH1200. The stock 11 inch shocks beat the $%@& out of my back and bottomed out constantly. These have improved my riding pleasure and have yet to bottom out, even with 2 up riding. One thing though, dont be stubborn like me and try to install them without putting the bike on a lift. A lift will save you aggrevation, and make installation a dream.
---------------------------
I'm 230-240lbs so maybe the 12" will be ok.

Should be fine with the 12" Had 12.5" 412's on my last Sportster and was just right .. Still had the Low look but enough Ground clearance to lean good and enough travel for comfort on the long haul ..

Is it necessary to lift the bike or can I manage without it for installation. I will be getting the shocks via UPS today.

if you are replacing the shocks with the same length, you might be able to do it without a lift, doing one at a time. otherwise, if you dont have a lift, try to set the frame on a cement block or something, then take off both rear shocks, and the rear wheel will drop a bit, then go from there

it would be best tho if you got a lift. I have this one from Harbor Freight, had it about 2 years now and use it all of the time, it has worked flawlessly for me.

I bought mine on sale for $69. right now they are $99, but you can always find 20% off coupons for HF, which would make it $80

it is an invaluable tool to have, you will use it more than you think. Hell, it's even handy to wash the bike, lets you rotate the wheels without moving the bike

Squeekie.
All things being equal, longer shocks have more travel and give a better,
more compliant ride. Longer shocks can use a softer spring.
Shorter shocks can ride just fine with the proper spring but the shorter you go the
more critical spring choice becomes,,then the more critical proper damping and
rebound becomes.

For looks,,low Is In, Lowering just the rear often increases straight line stability and
Increases the bar Input effort needed to turn the bike.
For ridablility, comfort, and cornering ability Tall Is the way,,as long as you can flat foot
the bike.

The Unescapable truth...Properly set up ssuspension looses 1/4 to 1/3 total
travel to "Sag", so,,,
The seat takes a little,,the tire takes a little, but not much.
then yer left with the suspension

A 13.5" shock,,,,,3.69" total shock travel and a 2.5" bump,,,Nuttin to It
A 12.5" shock,,,,,2.12" total shock travel and a 2.5" bump,,,ouch
A 11.5" shock,,,,,1.87" total shock travel and a 2.5" bump,,,well lets just say your gonna
need a cain when yer an old fart tryin ta get to the toilet on time XD
