Kinked and Bowed Hood - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Theoriginalsilverado · 11-05-2013, 09:38 PM

I'm sure if you haven't had it happen to your own square you've at least seen another square with the same problem- a kinked hood. It's a common problem. I was just wondering how you guys fix it.

I've managed to straighten mine out without detaching the hood, and making sure the springs are well greased afterwards- it will do wonders for the hood. But it'll still need straightening after time.

The only alternative I've found other than buying a new one or fixing the one you have is a hood brace kit from LMC, for a cheap $20.

Has anyone used the kit or have any advice pertaining to this topic? Please help me and many other square owners who have bows for a hood.

There's some other threads on here that goes into it a bit.

The hood kinking is actually a safety feature GM designed into the 73-80 trucks.

I usually just spot weld a couple of pieces of flat strap on the bottom side of the hood over the kink points. Its a whole lot cheaper than buying a kit.

I have it on my 78 and it stopped the kinking.

I prevented the hood crunch on my 76 by keeping the hinges and big springs lubed - there is a lot of exposed steel there to get rusty even in the desert.

I've added plug weld on the sides and steel underneath as well. However keeping it well lubed and when closing, pushing back, then down is a must

I put those LMC braces on my "77 so that the hood wouldn't kink. I wrenched in a Chevy dealership in the 70's those hoods would fold when they were new. $20 cheep and easy fix/insurance.

dumg question but what did you use ,I used some spray but I think it made it worse

cadillac_al · 11-08-2013, 08:33 PM

I think the owners manual says to use regular motor oil on the hinges. I'm surprised I don't ever see this. I have had about 5 squares over the last 30 years and never kinked a hood. My current truck hood was a little stiff last week and I oiled it. I have kinked a couple of my cutlass hoods years ago and I am sensitive to stiff hinges now.

I use Wurth HHS 2000 and spray the whole spring and hinge down.
