4/6 or 3.5/5? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

71super402 · 03-20-2006, 08:33 PM

Anybody have any pics of longbeds with either the 4/6 drop or 3.5/5 or even 4 in front with bags on the rear? I have a 71 longbed that I am going to drop and would like to go pretty low. Would love it if you guys could show pics of all three of the options mentioned above

Really not looking to do a full bag job all the way around, may still do some trailering....also, someone once told me that the standard 4/6 drop is not very functional on a longbed but that the 4/rear airbag would be fine? Anyone know why? Thanks ahead of time

ratrod67 · 03-20-2006, 08:56 PM

I have a 5 inch drop in front( 2 inch spindles and 3 inch springs) and 6 inch drop in back( 4 inch springs and 2 inch blocks)

71super402 · 03-20-2006, 09:22 PM

That looks really good ratrod! Do you have any sort of problems, that is really low for a longbed?

ratrod67 · 03-20-2006, 09:38 PM

I haven't had any problems yet. I do have to be careful because I have headers that hang pretty low but haven't hit them yet. Yea, it's pretty low.

HotRod71 · 03-20-2006, 09:44 PM

Did you need a Cnotch with that 6" drop?

ratrod67 · 03-20-2006, 09:57 PM

No. I did need an adjustable track bar though.

The fronts are 15X7 with 3 1/2 inch backspacing and a 235/60R15 tire.
The rears are 15X10 with 5 inch backspacing and a 345/55R15 drag radial.

Cool thanks

camaro__thunder · 03-20-2006, 10:34 PM

You have to have a drop of at least 4/6 in TX

71super402 · 03-20-2006, 10:46 PM

Anybody have any other pics? Maybe the 3.5/5 or airbag rear? Only on a longbed though if possible.

HotRod71 · 03-20-2006, 10:49 PM

Here is mine. I didn't lower it so I haven't a clue on the #'s. I do know that the front is sitting on the bumpstops.

HotRod71 · 03-20-2006, 10:53 PM

Sorry for the size. It shouldn't have been that big

71super402 · 03-21-2006, 05:02 PM

No one has a bagged rear end longbed or a 3.5/5 drop?

71chevytruckguy · 03-21-2006, 05:08 PM

im gonna have 3.5/5 on my 71 if i can ever get it put back together. here's the link to some stance photo's from early classic. the 3.5/5 is on the bottom. chris.

71super402 · 03-21-2006, 05:20 PM

Thanks Chris, I have seen those...I hate how high the back is compared to the front. I was thinking maybe going with the 4 inch drop up front and then bagging the rear, I was thinking I could just get the bags for now and spend the money on the compressor kit later? Know one seems to have pics of that setup though?

Slammed66 · 03-21-2006, 05:45 PM

heres 3/5 so a 3.5 /5 should be perfect I always wanted to bring the front down just a little bit more, its now a 6/rear bags But its also now a short box slowly coming together.

71super402 · 03-21-2006, 05:53 PM

Thanks slammed, how is the driveability of that combo? How did you do it and how much was the total if you don't mind me asking. thanks

Slammed66 · 03-21-2006, 05:58 PM

I know its ghetto but ive done it a few tine and never had an issue , I cut 1 coil off the front coils ( NOT USING A TORCH) but slowly with a very thin zip cut on the grinder.

I bought new rear drop coils for the back for a bit over $200 cdn I beleive

I never ever had any issues , I drove it like that year round and I used it as a truck, loved it handled great rode nice , I loved it , well see how much I like the 6 inch fron drop ,

with the bags out back should be like a 6/8 drop

71super402 · 03-21-2006, 06:20 PM

did you use dropped spindles along with cutting the springs? also did you use a adjustable panhard bar out back? I keep hearing that you get alignment issues without it.

Slammed66 · 03-21-2006, 07:12 PM

No drop spindles, still had drum brakes on the front

No adjustanble hard bar on the rear I never had an issue , Ive seen it going down the road once , didnt dog track

But Ive heard they are reccomended

I did install em on both trucks with a severe drop tho.
