Is the suspension on a 73-87 chevy C-20 and C-30 the same.
 

I am looking for a lowering kit for my '82 C-20. All I can find is kits for lowering one tons. Is the suspension similar between a C-20 and C-30? Will the C-30 kit work on my C-20? Thanks

I think?
 

I know the ball joints are the same. You might contact Early Classic Enterpises for there C20 drop spindles.
