1977 vs. 1984 Suspension

[MobSled]

Wondering if the lowering kit from a 1984 shortbed would fit on a 1977 longbed???? Shakles, shock extenders, leaf pack, blocks, U bolts, springs, swaybar etc....

Spindles will likely be different (1" and 1.25" rotors), and there are two different length leaf springs...other than that, most should be interchangable.

No spindles included, just 3 inch lowering springs. So the leafsprings wont fit from a short onto a longbed?

I`m assuming 56" will fit and the 52s wont?

The length of the bed has nothing to do with it (as previously mentioned, there were two diff length available)...you will have to measure to be sure.

Bingo! An easy way is to look and see where your rear hangers sit on the frame. If they are tight to the bumper brackets, you have the long springs...if there is about 4" between the hanges and bumper brackets, you have the short springs. Measuring is always best, but this will tell you easily as well.

No matter what I can make both lengths fit by relocating the hangers?

Yes, but it is a PITA. They are riveted on.

[bigblock73]

They will both physically fit, but you'll have to relocate the rear hangers if you change the length of the springs in your truck.

Gotcha...everything else as in the front lowering springs is the same and will go right on?

[MobSled]

Anything on the front lower swaybar?

Should. The only thing is the sway bar...if both trucks have one, then easy...if your truck doesn't, you will need to remove the mounts on the donor (they are riveted on).
