How did they lower my rear? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CSoliz · 12-05-2010, 09:16 PM

My truck is a 78 Big 10 shorty. My Uncle who owned it before me had a shop lower it and doesn't know how they did. I am not that familiar with leafs, if it was a 63-66 I wouldn't need to ask, but I need some schooling on this. It is supposed to be a 4" drop.

What ya think?

Is the front hanger reversed? You'll know because it will have bolts instead of rivets.

The leafs are below the axel. Stock, they are above the axel.

JW76 · 12-05-2010, 09:25 PM

isn't that a flip kit? normally the leafs are on top of axle

CSoliz · 12-05-2010, 09:27 PM

the hanger in the front is still riveted to the frame.

**lolife99** · 12-05-2010, 09:27 PM

It's had a flip kit installed.
The rearend is now on top of the leaf springs.
Probably a 5" or 6" rear drop.
Looks fine to me,... but I'm not sure about the red rubber snubber back by the rear shackle.

it is, but I thought flip kits get you in the 6" drop range. Or am I wrong on that?

I don't think it is dropped 5 or 6" though. Maybe I'm wrong, here is a pic of my truck.

CSoliz · 12-05-2010, 09:37 PM

would the snubbers take some of the arch out of leafs giving it less drop?

875.3CHEVY · 12-05-2010, 09:39 PM

looks like a bunch of leaf springs.i counted 8 that may be holding you up.is that part of the big 10 package.

CSoliz · 12-05-2010, 09:43 PM

it may be, they call it a "heavy half ton". its GVW is about 6200. How many leafs does a regular 1/2t have?

joe231 · 12-05-2010, 09:44 PM

What size tires?

That is more than 4" in the rear.
I'm guessing somewhere in the 5"-7" range
Measure from the middle of the wheels to the top of the wheel opening front and rear.

CSoliz · 12-05-2010, 09:52 PM

Center of the wheel to fender (wheel opening)
front 14 1/4"
rear 15 1/4"

joe231 · 12-05-2010, 09:57 PM

looks like just a flip out back

bigblock73 · 12-05-2010, 10:18 PM

Measure the leaf pack thickness at the axle, add 3" (axle tube diameter), and there is roughly your drop. You have bout a 6" drop due to the HD leafs in your truck

CSoliz · 12-05-2010, 10:57 PM

So how much lower can I go? and if I want to go lower out back I need to remove leafs and add shackles so I'm not to low, right?

KQQL IT · 12-06-2010, 12:21 AM

Any much lower and it will need a C-notch

80stepsideguy · 12-06-2010, 03:28 AM

I wouldn`t go any lower then that, looks good as it is.I had a flip kit and a 2 inch bell tech hanger drop in the front and a shackle kit in the rear and it was way to low.I sold the bell tech kit and just did a flip kit and it sits level like yours and lowered.So unless you want to spend money you can do a air ride kit but thats all in your budget...

thanks
