Not sure why they went with a 2 piece drive shaft on these trucks? Thanks

replace it with a one piece shaft, usually you can find one that is close in length, for example a longbed driveshaft is usually 64" overall and a reg cab colorado driveshaft is 54" long. when you factor in that lowering the rear makes the driveshaft shorter (lowering an s10 you usually shorten a driveshaft 1" to keep the yoke from cramming into the trans) so 54 is almost perfect.


measure your driveshaft to be sure, center of u joint to center of u joint. I dont recommend shortening the two piece because the front shaft will end up ~12" long and you will want to replace the carrier bearing while you are working on it, might as well just put that towards a one piece.

Re: S10 Swap how to

As a guide if anyone is interested in what measurements you end up with using a 4 1/2" front cab mount and how it affects ride height and all the other measurements. Measurements are without any suspension modifications. The cab mount also has a 1/2" rubber mount on top for a total of 5" from top of frame to bottom of the cab cross member that contains the mount hole.

Re: S10 Swap how to

Thanks for posting the measurements. Is this the typical tire sizes guys are using front and back? Not that there's a standard, but what have you found works well for wheel sizes for a lowered look?

Diagram doesn't have the front tire size I would go for, but that's what is on the car so I had to take measurements from there. I'll probably update the diagram when I get a new front tire. The rear ones are new and I did enough research of various builds that the average tire diameter is 29" for the front and rear. The size does fill the rear fender out fairly nicely and tucks in well for a lowered truck.

Tucked in with the right spacers and 2" drop spindles, 29"x8" front tires seems to be the consensus, but I haven't tried that myself yet to confirm that there is no rubbing.

Borrowed from a different thread:

Re: S10 Swap how to

i beg to differ, i have used two piece shafts and old carrier bearings many times and never had a problem i just shorten the front half, and it is NEVER anywhere near 12" long! works out nicely, cause you don't have to mess with moving the carrier bearing.

looks like you are right, 12" would be much longer than the actual measurement. my comment was actually about cost, a rcsb driveshaft is $50-60 in a salvage, shortening a two piece would be double that and you would probably replace the carrier "while you were in there"

Re: S10 Swap how to

Glad to see this thread is still active. My 14 year old son and I are currently working on a swap just like this have built cab mounts very similar to the design shown only using 4" square tubing (son actually did all the welding to assemble the mounts. have moved the motor into position and made mounts and are currently working on the core support.
All the info here is great look forward to getting this truck together and running. We are using the 4.3 vortec out of the 1998 s10 we purchased and using the 4L60E that was behind it. Also had a 2001 short bed we used as a frame donor stretched it to 116" as others have previously mentioned. The short bed had no engine or tranny when we purchased but did have the old tranny cross member in the bed which I was able to rework to act as a trans support and only had to drill 2 holes in the frame. Any suggestions for brake pedal since both our s10s have the huge aluminum casting assembly and they don't look like they would be easy to remove or rework for repurposing in the 48?

I had used the 4x4 tubing at 4 1/4". Worked a charm. I did cut a little notch from mine and glad I did. It barely clears the edge of the lower cab corner when lowering the cab onto them. Feel free to check out my project build for a core support mount.

That's how I made it work. I actually used one half of a 4wd drive shaft and the other was from a 2wd. I had to fabricate a bracket to set the carrier bearing back. It won't be my permanent solution but was able to make it work for free and right away.

Re: S10 Swap how to

A drive shaft from a late '90's caprice or roadmaster will work fine using a V8 and 4L60 tranny if you want to go with one piece.

I have made a big interface bracket on a couple trucks to use the 98-03 pedal bracket but I have changed my tune lately, its very heavy and needs a lot of reinforcing.

If you want a simple brake pedal setup, skymangs shows how to use a 82-93 s10 pedal bracket on page 2.

Re: S10 Swap how to

this is a shortened 2 piece driveshaft, no where near 12" long with the original carrier bearing. we have been driving it for over 4 years now, so don't tell me it can't be done! cost about $100 to have a driveshaft shortened/balanced. i don't know about you, but i don't have time to go scrounging around a j/y every build.

scrounging? I call them on the phone and say I need this driveshaft. the last one was 60 bucks and wasnt any more driving than it takes to go to the driveshaft shop, and I had it to install the same day. add to that, the 98+ longbeds came with a one piece shaft, so they dont even have a carrier bearing crossmember.

I can agree to disagree, but dang if it doesnt seem like your way is the "more money more work more time" way.

edit: and I am looking again, your trans is a TH350 which is shorter than the 4L60e in my picture.
