1/2 ton to 3/4 ton????????

[bad_turbo]

I have a '67 1/2 ton burb 4x4 all stock. Really wish it was a 3/4 ton. I just picked up a '68 GMC 3/4 ton 4x4 truck. It looks to have a 4 inch lift on it. Was thinking about taking parts off the truck for my burb. Would the lift kit and axles swap without too many headaches? I measured the leafsprings and the lengths were the same. The only difference I found was the front leafs on my stock burb were narrower in the middle than on the ends and the leafs on the truck were the same width the whole length of the spring. What exactly is a shackle flip, also? Thanks

Turns the factory rear tension shackle into a compression shackle for 2 1/2 or 4 inches of lift without using blocks.

Why do you want a 3/4 ton?The rear axle is really the only thing different besides the springs.The 1/2 ton uses the same front axle from the knuckles out or somewhere close.You can get 3/4 ton brakes,hubs,etc and convert the front to 8 hole from a 6 hole.Its really no stronger.The GMC most likely still has dana 60 rear,which is an ok axle.The lift will already bolt to your 67,the 67-68s used the same leaf configurations.If I was going to do it,I would just swap the lift.The only reason I would consider swapping to 3/4 ton was if the new axle had discs.And to answer the questions,the axles will bolt up if the 3/4 ton is really a 68.69 + wont bolt up directly.You will have fun removing bolts,ect to swap springs but the lift is a simple task for most

just swap the lift over and call it good and put the 3/4 emblems on it
