i was wondering if any one has put one in there truck, or some one know how you could, seeing how it's way down on the floor.
 
For the Sm465? I don't know if one exists for that thing. You could cut down a shifter, but that wouldn't really be a short throw shifter. About the only way to do it would be to modify the shift tower where the shifter hooks to the trans.

I've seen on FWD cars where they cut the piviot ball of the shaft, and move it up then re-weld it. I don't think this would be possible with the 465 though.
 
Only change to a 465 is to get the later upper piece that contains the shift mechanism including the forks. I *think* this was '88+?
 
Believe you are correct. The "tunnels" that the shift pins travel in protrude from one end or the other, which they don't do on the earlier 465's also, which is another dead giveaway.
 
The newer truck version (88+) moves the whole shifter back 3 or 4 inches, maybe even a little more and you have to have the newer stick to go with it witch angles back quite a bit more. In a blazer with bucket seats it may not be too bad but a reg cab pickup it may present some problems.

I didnt measure But I kow if you try to put an old style in the newer truck the shifter hole ends up under the trans tunnel. The new top centered the shifter hole with the hole in the trans tunnel. So 4-3 inchs is an estimate.

It does shorten the shift throw a little bit but not by much. Your talking about a truck transmission that was never meant to be quick shifted. You cant modify the shifter ball either it just ends up too long and you cant get the retaining ring on it.
 
now that's pretty cool! i might try to fab up something like that... maybe. i don't like the way it looks, but a short throw would be nice.
 
Interesting idea. I wonder how the shift feel is with that. Can you tell when you are in the right gear? It is obvious how the shifting works fore and aft but what about left and right? It seems like it may be a little iffy going along the "H".
 
the OP never specified about the 465.......but there is one for the nv4500 for sure. I used it in mine, it seriously cut the throw distance in half. no difference for telling what gear your in after using it for a while. and its a much more positive/tighter shift feel. not loose and floating like it used to be.
 
could someone explain to me how one of these kits would actually shorten the throw of the shifter? I understand how the mechanism works but it seems to me that all it would do is relocate the position of the shifter so if someone could explain it I would appreciate it.

that being said I like the looks of some of the homemade models done on pirate and may try to build one similar if I end up swapping in a sm465.

The position of the piviot of the shaft that controls stick inside the trans, in relation to the piviot of the handle you grab, can shorten the throw of the handle you grab. Make sense, I know it does to me.
 
that explanation makes some sense, but i'll try to clarify.

imagine a lever of some very long length (such as a shift rod), and that it's fixed to a rotating point at one end. to shift from one gear to another is a fixed angle of motion. for sake of discussion, lets say that to shift from first to second gear, you have to move the shifter 20* (that's an arbitrary guess). the shorter your lever, the shorter the lateral distance you have to move. so, if your hand is on top of a 10foot pole and you want to rotate that pole 20*, you have to move a very long way. if that pole is only a foot long, the distance you have to move to change it by 20* is much shorter.

all this kit does is effectively shorten the shifter to a length equal to the distance from the arm that goes over to the trans. ball to the top of the shift rod. ;)

is that a bit more clear?
 
heres a couple of pics 1 is the stock lever 2 is the short throw lever. notice the length difference between the pivot and the foot. the geometry change is what shortens the "throw" its a simple lever and fulcrum dynamic. you raise the pivot up by installing a longer lever, and you add a spacer under the shift tower. so you loose torque but gain speed. you know teeter totter....move the pivot around.


I had a pic of them sideby side but I don't know where it went......
