63" Chevy's into B2... Need some advice!

63" Chevy's into B2... The Progress Continues

I am just starting on my 63" swap. I got a set of Teraflex lift shackles, and 5.5" lift ProComp 63" springs. My goal was to lose the old Skyjacker springs and blocks and gain a bit of flex. I already pulled the overload and angle shim out of the spring pack. My question is. Will the front spring mounting be in an ok place? Its obviously only mocked up in the pics and havent made gussets and such. I dont have any scrape marks on my old springs, radius arms or frame in that area. But I am wondering if its ok to mount them there. How will it affect my roll center? Is it worth all the extra work to move them up an inch or so? What do you guys think?

Here is what I have come up with so far... it doesnt hand any lower than my radius arm mounts and the truck sits level with NO BLOCKS!! I wonder if its worth modifying the front mount a bit more to gain maybe another inch of clearance, but then I might need to add the overload strictly for height. Should I just leave it along and get to fabbin'??? As soon as I get this done, I can drop the 60 in. Hopefully with these springs and Ruff Stuff spring perches, I can ditch the traction bar.

I have to say, this may be tech library worthy. Looks good keep going.

I would have inboarded them

 

[59bisquik]

Inboarding then wouldnt of gained any ground clearance since they are already even with the bottom of the frame. Most likely it would of made it much less stable from the springs being quite a bit closer together.

Where did you get the shackles from Shay? I've been looking for something beefier to replace my homemade ones.

 

[59bisquik]

Sasquatch,
They are Teraflex XJ shackles

Why not use the stock front hangers and then move your rear out to the bumper? It seems like this is a better option. I'm currently pondering how I'm gonna do my setup as well.

 

[59bisquik]

The thought has crossed my mind about doing it that way. However, not sure about fuel tank interference and also what my sheetmetal would look like. The 6" stretch would sure make it a better wheeler, but again, concerned with sheetmetal and the fuel tank.

I wouldn't suggest running the springs without the OL leafs, you'd be chancing spring fatigue right at the leaf perch (not to mention it will also increase spring windup).
Find some flatter overload leafs to put in there (say, stock RBV ones maybe) and mount them with the long side forward. This will maintain some support under the leaves right at the axle perch without hindering your flex much.


I can only see good from a handling aspect with the mount below the frame like that, however as you already noted, you do lose clearance. I think the springs being longer would provide some of the same benefits as the lower mount would (less flex steer, etc.) which I think it might be worth the time to fab up a bracket to mount them on the side of the frame (incorporating the body mount bracket into it) to gain some clearance.
Don't get real hopeful about ditching your traction bar with leafs in a SOA config though.


FWIW, I moved my axle back 3" and no clearance issues with the fuel tank or it's skid plate, so you'd only have to go about 3" forward with the mounts while using the Chevy leafs to put your axle in a similar position as mine. YMMV with the D60 though.

 

[59bisquik]

I might put the OL's back in and play with it some more. Im actually toying with the idea of going the full 6". It should just clear the tank. Looks like the shackles would go on the back of the bumper or even on the inside of the bumper... maybe get carried away with the body work and try this...

 

[AZFX4]

Yeah I have thought about the fuel tank clearance, my sheet metal is already cut off back pretty far. I also have a chopped top and have been thinking about mounting a fuel cell up higher in the back so I wouldnt have to worry about that part. Im not sure I want to undertake all that at this point. Im alrady dying to get this thing out in the dirt.

 

[59bisquik]

Looks like 3" back will be where I start. 6" with a D60 puts me right into the fuel tank. That is one big differential! I will keep you updated on my new mounts and progress.

 

[06RangerXLT]

i vote moving the tank

i like the spot, but it will be a bitch if you need to do anythint to that body mount.

 

[dangerranger83]

Replace/upgrade what you can with the body mount now and you wont have to worry about it for a good long time.
