Id say nv4500 or a gear vendors overdrive unit.

Another option is a Ranger overdrive gear splitter.

Everyone has their arguments for why they think one option or the other is better. Personally, the NV4500 would be the less desirable option, but that's what most people do to gain overdrive.

Is that like a gear venders just different name im assuming? Im going nv4500 cause its cheaper then gear vendors at least so far lol. What about a nv4500 and a overdrive unit!?

Ranger is a 2 speed unit to go in front of the SM465, you end up with two separate shifters. Simple and effective. Everything moves back 4 inches I think, and obviously the driveshafts need adjusted. It's cheaper than a GV, all speeds work in 4x4, and no t-case and bellhousing adapting like a 4500.

If I had an auto, I'd choose the GV because it's just so dang simple. Bolt it on and shorten the rear shaft, bam you have OD.

Another thing with the gear splitter, if you also twin-stick the 205, it's a great theft deterrent. Most thieves probably don't even know how to drive a truck with one shifter poking through the floor, let alone 4 of them.

Now that would be cool!

I like the Ranger option as well.
If I ever feel the need to add more gears to my truck, I think that is the way I will go.

Mine has a 454 and the SM 465 in it.

I’ve long lusted for a GV overdrive. This thread has spurred my interest in a Ranger Splitter.

Overall easiest is probably an NV4500 swap. There are other options, sure, but not sure if easy = best.

 

[Duramax]

Well I’m stuck on what to try but at 65mph my truck is screaming pretty good. I have 410 gears and a 454 the fuel consumption is incredible lol. I would like to change the trans to a smoother shifting setup with more gear options which is why I was interested in the nv4500.

I know the shifter on the 465 is shaped to clear the dash when in the forward position gears, but does it still clear the seat when moved back to accommodate the range splitter when in the rearward position? Or does it require some messaging of shape or switching to the new shift tower design from '92ish?

I've read that the shifter needs bent slightly, but don't know first hand. The later shifter and tower would move it back even further, but at that point it it should work well with a nearly straight stick. It's a combo I want to try someday.

Nice ride. I’m right there with you. I can’t justify an NV4500 because my 465 works just fine and will probably last forever. The ranger od sounds cool, cheaper than a gear vendor. Shifter won’t clear the seat in all positions with that unit though.

This is my ‘85 454 4 speed 4.10 ratio 9 mpg gas hog.
