Rear broken shock mount - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone ever experience a broken rear upper shock mount? I was adjusting my rear brakes today and noticed. I will have to get it welded.

Pretty common problem on these old trucks. I have made a plate and used a couple of big washers to fix it temporarily until I could weld it up.

It's best to reinforce them when this happens. beat the crack straight, weld the gap then weld on a plate and mount your shocks on it.

Drill the end of the crack to stop if from going any further too.

Does it look anything like this lol Im going to drill the end of the crack, and plate it. My truck will be bagged so I wont be using the stock shock location anyways.

They really should have made the upper rear shock mount a double shear design. Every one of them I have ever seen has been wallowed out or torn up. Just too much pounding for a single mount point stud.

I'm going to fab up a secondary bracket for mine and convert it to a through bolt design.

kunzy420..... looks EXACTLY like that lol... Thanks for the info guys. I agree it's a pretty lame design IMO

Does anyone know a part number for the stud that goes through the frame where the shock bolts to? I ended up having to cut mine since the backside nut was completed corroded to the stud. Hopefully these are still available to purchase.

If you cant get the studs, Ill check my shocks to see if mine are still attached/useable..and send them to you. like I said if you cant find any or fab anything up.

Pretty much any auto parts store that sells shocks will have them or can get them.
