Flip kit or dropped leafs and shackles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

tranz am · 04-11-2007, 06:26 PM

There are 2 ways I can go when dropping the rear of my 69 GMC, Flip kit or dropped leafs and shackles. The flip kit sure costs alot less but I will lose alot of my suspension travel in the process even with a c notch. The dropped leafs are much more expensive but save my susspension travel.
What is more performance oriented? What will handle better?
I would like to know what other peoples opinions are on the 2 set ups, pros/cons
Thanks

Flip kit.

You will lose some travel w/both methods.
The dropped leafs/shackles will give you about 5" of drop & a flip kit nets between 5~6" of drop @ a lower cost.
The flip kit does not compromise the hauling capacity (other than the lost suspension travel).
Dropped leafs may/may not compromise hauling capacity depending on the springs manufacturer.

Lowering the truck either way will improve handling because of the lower center of gravity. Add some quality sway-bars & bushings w/some good shocks & tires to get the most out of the suspension regardless of way you decide to drop the rear.

I'm in the same boat, not sure which way to go. The only thing holding me back with the flip kit is welding in the c-notch, cause I have no welding skills. It is really cheap though.

I went with the dropped leafs and shackles from GMCPauls (they offer drop leafs with up to a 5" drop and their shackles will give you another 1" or 2" drop). Unfortunately, they are not yet installed on my '71. I ordered new KYB Gas Adjust shocks, 2.5" drop spindles and 1" drop front springs, with a 3.5"/6" final drop in mind. Also ordered poly bushings and low profile sway bar brackets for my OE bar up front. Hope to post some before and after pics within the next 30 days. Am real interested as to how it will change the handling and ride.

Converting it to coils would be nice.

I flipped mine but havent notched it yet, but will by summer.

Keep in mind, no matter how you lower it, you will lose the same amount of travel. Whether you use a spring and shackle combined for 6 inch drop or a 6 inch flip kit, the axle will set 6 inches closer to the frame. What I'm saying is that inch for inch, you lose the same amount of travel no matter how you lower it.

I see your point, cheep or expensive, I still have the same problem. Looks like I will c notch the frame and use a flip kit. Thanks!

They offer bolt-in c-notches. The frame rails are the same for leaf & coil 1/2 ton 2wd trucks.

Yeah I might go that route, get someone to weld them later. You cant beat the price for the flip kits and bolt-in c-notches.

Orange · 05-31-2007, 04:19 PM

Where are you guys buying the flip/c-notch kits?

That's how I initially did mine. They were bolted in until I started pulling my trailer. I felt the added insurance from welding them in was worth the effort.

GREASEMONKEY72 · 05-31-2007, 07:37 PM

trailer or not id weld up the bolt in notches just for the extra security and strength

Orange · 05-31-2007, 08:23 PM

I'm having no problem finding the C-Notch's, but the flip kit is a different story...

Does everything just relocate correctly magically when you put the springs on top of the axle, I wouldn't think so...

im sure the pinion angle would change a bit but other than that i think everything else would be fine, exept shocks being to long

KAILUAZ · 05-31-2007, 08:47 PM

You have to be careful with the spring width, IIRC the older springs are wider so the 73+ flip kits wont work.

Actually, it's the opposite. Pre-73 leaf width is 2.25"; post 72 leaf width is 2.5".

Orange · 06-01-2007, 07:38 AM

Corn - how did you flip yours, what was involved?
