I'm new around here and to the four wheels as well...grew up on two wheels. I have a 93 300 ex that I have an extended swingarm for and would like to know what all rear shocks will fit on this mod. The shock mounts are still where stock would be....looking for options.
Thanks!

If you measure you stock rear shock eye to eye, you can just match up lengths

The 300EX uses a linkage rear end. In order to make the 660 shock fit you have to remove the linkage system. You are the mounting the shock where the rear linkage normally attaches. That is HARDLY the correct angle for the shock to work properly.

Linkage???

Linkage??? The 300ex has no linkage...at least not on mine...shock bolts up to swingarm and to frame just in front of the air box.

250X and 300EX carry the same suspension and swing arm. the 400EX has the same type set-up as the 450R

My mistake, the Raptor has a linkage. You are attempting to make a shock that is meant to use a linkage work without one

This is correct however the shock lengths are the same within a 1/4 inch or so and I have heard of alot of people using the raptor shock on the 250 and 300 because of the remote resi. and the smoother ride. the link bar on the quads that have them eg. 450R for example is for more travel, stability roll, and a smoother ride the more race tune quads have them correct?

The linkage provides longer shock travel. My point is that to use a 660 shock you are drastically changing the geometry at which the shock was designed to work.

figurativley a shock is basically a cylinder, a hydrolic cylinder sees side load as resistance.. and is bushed at the rod accordingly to the side load it recieves, wouldn't the point of the linkage be to gain travel, while retaining the side load that a shock to swinger set up would posses? the answer to your point would be knowing if the linkage would actually lower the resistence to the swing point.. . if the linkage and shock has a lower side load than the shock to swinger. then its possible the 660 shock is less bushed,, than the 300ex.. also a cylinder or shock is only designed to work up and down... the linkage transfers all energy to the shock in a up or down manner... this includes side load

My theory would actually be that they are bushed equally hence the absence of the linkage would have no affect as long as the allotted travel is the same...
right or wrong its my .02c :)

Shocks are dumb devices and they don't have a clue whats shoving them up and down... linkage or not. The link can provide more wheel travel on a shorter shock and also build in more or less progression to the travel. Shocks are simply built with spring and valving to match the needs of the suspension. Clearly no one here posses those facts... including myself. However, putting a 660 shock on a 300 has been done many times simply because it FITS. The result has been reported to be an improvement over a stock 300ex shock. So if you are gonna look for an ebay style upgrade and not spend the money on valving then this is the only known $50 improvement most of us has ever heard of. Run with it and don't over think it. Or break out your checkbook for an aftermarket solution.

I'm just not the type of person to use something because it fits. I would much rather spend a few more bucks and have something that was built for that application.

its all good red, I like to do things the right way too but this time i'm being cautious due to gf may lose interest, or maybe can't handle it, she's fairly aggressive on trails so we shall see, i will run one until my gf might benefit from somethimg long travel, but she will just be starting to ride mx this coming summer, :) she is almost set up..

If we were all the same this world would bore me :)

the raptor shock will fit with no mod except maybe a longer res hose to mount the resi better
