1973-1991 One Ton Rear Main Eye Hangers for K30, 4WD Conversion C30, and 4WD Conversion C20 Crew Cab

This new bracket set fits a lot of trucks and solves a lot of problems.  It started as a replacement main eye hanger for K30s to fix bracket damage but as we started looking at converting 2wd 1-ton trucks to use the 4wd height brackets, it worked out that the same bracket can do that job too.  And along those same lines, the early K30 trucks that used 2wd height rear spring and shackle hangers can use this bracket set to convert the main eye hangers to 4wd height.  And C20 crewcabs can use this just like a C30 would.  We love GM’s modularity and this is another great example.  It literally fits ANY squarebody crewcab or 1-ton from 73-91.

-Converts C30s to 4wd height main eye hangers

-HD replacement for 4wd main eye hangers

-Converts early K30s with 2wd height main eye hangers to 4wd height

-Works on C20 crewcabs too.  Check to verify 40.5” center to center spring width to confirm

Notes on 2wd vs. 4wd hanger height:
GM essentially lifted the 4wd trucks compared to the 2wd trucks by building rear spring locating brackets that push the truck away from the springs by a couple inches.  When you’re converting a 2wd to 4wd you either need to use more lift in the rear suspension or use our conversion brackets to make it use the same height components as the front.  For example, to lift a ’85 K30 we’d use a 4” lift spring in the front and in the rear.  To lift a C30 that’s converted to 4wd we would use a 4” lift spring in the front but would have to use a 6” lift spring or maybe a little more in the rear.  These brackets fix the front eye hanger to 4wd height so you would treat the rear suspension just like a “K” truck.

You will still need to address the rear shackle hanger with either a shackle flip or our replacement tension shackle hanger system.
