Jul 21st, 2025 | | | | Joined: Mar 2008 Posts: 374 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 374 | I ordered and received parts from a vendor to replace my shackle bushings and front/rear single bushings on my 1946 1/2 ton leafsprings. The bushing that goes in the 'front of the rear leaf spring' and in the 'rear of the front leaf spring' are what I am concerned about. If you see the picture below, the bushings/bolt/jam nut I received from a reliable vendor look very different from the ones the local auto parts store sells even though both state they are specifically for a 1946 1/2 ton Chevrolet truck. I want to make sure I have the right parts BEFORE I start disassembly. Any help is greatly appreciated. Thanks Stovebolters! pics of what I got vs. what another sells | | | | | Joined: Apr 2010 Posts: 232 'Bolter | | 'Bolter Joined: Apr 2010 Posts: 232 | What the FLAPS shows are king pins, not shackle bushings. | | | | | Joined: Mar 2008 Posts: 374 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 374 | Nice 68ironhead... thats what I needed to know.

Kingpins need two bushings. And, if your spring mount has a place for the lock pin, I suppose both designs would accomplish the same task. | | | | | Joined: Nov 2010 Posts: 109 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2010 Posts: 109 | | | | | | Joined: Jan 2009 Posts: 1,644 Shop Shark | | Shop Shark Joined: Jan 2009 Posts: 1,644 | The one that the FLAPS shows are for 3/4 and 1 ton trucks,thats not a king pin set.Last year I replaced all the spring bushings on my 53 GMC project and thats whats in there.You'll need the other ones for a 1/2 ton. I've never worked on a pre 47 truck so I realy don't know what came in them.

I also got these for the back of the back leaf springs and the fronts of the front leaf springs. I will keep yall posted on fit, etc. shackles

Back in the forties GM was GMC wasn't it? As in GMC is the parent Chevy is the child.
If you look at GMC spring parts @ rockauto for the mentioned years you'll find the 'Bolt' type not the 'pin' type.
Give me ambiguity
or give me something else
