1984 K30 "C4" Truggy on Rockwells

What did your wheelbase end up and how long is that rear shaft?
 
What did your wheelbase end up and how long is that rear shaft?

Wheelbase is virtually right at 138" and the rear shaft ended up being 68" long. Pretty long, so he did it out of larger diameter tube that is just a little bit thicker too. The nice thing though is they're rockwells so the pinion is up really high compared to axle center line. So even though it's a long rear shaft, the whole driveshaft is virtually tucked up inside the frame rails almost the whole way. That first side profile pic above (and on the video too) shows how nice it's tucked up under there. The more I'm messing with these rockwells the more I love them
 
If you have the equivalent of 8" of lift up front. And stock springs in the back, is the rear lift coming from moving the brackets forward? The flip kit is only 4" right?

I would say it's a factor of many different things as to why this setup work out to be like it does. One is even though they're 4" lift springs in the front, I purposely got a set that has a little softer spring rate, and with the weight of the BBC up front, they sag just a bit. So saying it's an 8" total lift probably isn't accurate. Then on the rear even with the brackets moved forward they're still bolted to the same "height" on the frame as where they were stock, but when I drilled and bolted the shackle flip, I purposely did it so the shackle angle was a little more up and down than what most people do, which does gain you a little lift by doing too. Plus, the rear has virtually no weight on it which adds to this too. Now, that will change by some later when I start adding tube, but it shouldn't be too much that it really affects the stance.

So what I'm trying to say is applying the standard thought of "52's up front give you 4" of lift so a 4" lift 52 will give you 8" of lift...and it's a 4" shackle flip so I should have 4" of lift" doesn't apply as much with a build as custom as this. I had to make small tweaks to suspension setup as I went to ensure that I got it to sit somewhat level like it does.

Any thread that a 6.2 dies and a bbc lives on is a good thread.

Amen brother
 
I'm interested because sans Rockwell's, mine will be very similar by winter.
Probably keep my current spring setup for now, but Wanted to verify the rear wouldn't raise on me lol.

Yeah I was thinking Rockwells are the only way that kind of shaft works, at least in my experience. It is nearly invisible in that side photo. :thumb:

My @Kay86K5 inspired frame chop is ending up at 141" wheelbase. Difference is mostly due to me installing the 56" springs backwards.

Yeah, and I moved my front axle forward quite a bit too. I used a b52 kit but put it in the most forward position it could be, then put the spring eye in the most forward hole, then the RuffStuff simple swap kit has multiple position holes for axle placement too and I put the spring pin in the most forward hole there as well. I would venture to say the front axle is about 3-4" forward from its stock location. So to get the wheelbase that short I bolted the rear leaf spring front hanger virtually right under the rear part of the cab. With the tire size I wanna eventually run, that was about as far forward as I could get it.

But obviously mine is a dedicated off-road rig so I wanted to get it as short as I could. I could see in your case going a smidge longer of a wheelbase isn't going to hurt you for how you use the rig. Will still be an upgrade as you've been used to wheeling a land yacht to begin with ;)

Lol. 140-142 was my goal. :thumb:

Easy peasy :waytogo:
 
That explains why you're only 3" shorter because I figured you would have moved you rear axle further forward than I did. I still might move my front axle up another hole in the B52 but I would still be 1 hole from the end.

As you pointed out, wheelbase was not my reason for the hack. My biggest goal was shortening the truck enough to fit in our garage. With an 8' door, it will fit better than the C10 even. Aside from that I was ready to ditch the saddle tanks and always wanted to fab a bed.
 
I have a few little dirt piles in my property so tried to flex it out a little. Obviously wasn’t able to get full flex, but still does alright. I never was building the suspension to be max flex type of stuff, but seems to flex good none the less. I think it’ll work pretty good overall with the longer wheelbase. I also wanted to double check to make sure everything with the center chunk was clearing in the front. It all looks good09A60F6D-966E-4B37-A84B-03F1ED91480F.jpeg064D640B-25F9-4CF3-A734-0A574C0EFE25.jpeg7BC5B24B-21A5-46C1-A83A-90FA3EF9DD50.jpegDE21586B-1CFE-42C3-9BC0-E652486A4706.jpeg
