These are the same as our standard spring hangers except they are designed to be recessed into the frame of your Toyota when using longer leaf springs like the Chevy 63's. If you don't want to increase your ride height too much these will help.
ID dimension is 3" with a 9/16" hole made from 1/4". Comes with plates that you can weld it to box the hanger to make these even stronger.
Sold in pairs
