Let's see some pics of 4-6 and 5-7 drops on 71-72 c 10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

7d1truckguy · 10-29-2013, 10:10 PM

I want to get some idea's on if I want to go 4-6 or 5-7 on my 71 gmc with leaf springs on the rear I will probably keep these 15x8 ralley's until I can afford 20x8 and 20x10 torq thrust II

This should give you a good idea, very similar to what your lookin for

Are these drops just done with springs, or is there more to it so that you can still get a proper alignment after the drop?

**leddzepp** · 10-30-2013, 12:25 AM

2.5" dropped spindles in front (no change to geometry), combined with one cut coil on each original spring for another 2.5-3". Added one additional shim to each mounting point on the upper control arms. Aligned perfectly and drives straight down the road. 5" drop springs combined with 2" blocks in the rear.

i love the 5/7 look, especially with rally wheels and raised white letters. nice truck. you need frame mods for 7" right?

Thanks. Yes you need to c-notch for clearance. Even with CPP 5" springs I bottomed out all the time and it needed then. Opinions and numbers seem to be all over the place as to when it is "required". I recommend installing the springs and using your own judgement.

Looks wicked. How is your scrub line in the back with the 2" blocks and those wheels? I measured mine and best I could get before I starting hitting hard parts was 1.5" with blocks. 2" was really close.

4.5/6 ECE drop with NO c-notch installed.

Installed the ECE kit a few months back. Total drop of 4/7 to even out the stance. Added a 1" lowering block in the rear. C-notch to follow.

17" TTII's w/ 255/55/17 on all 4 corners

This is actually the set up I want to go with (only difference being the gunmetal gray wheels) but I am leaning towards 255/45r18 for two reasons 1) I am having a really tough time finding your size tire, 2) I wasn't sure if that extra inch diameter would fit under my truck.

Do you mind me asking where you got your set up? And I'm not sure the drop on my truck, but do you think they would fit? I have 215/70r15 on the fronts right now for comparison.

**leddzepp** · 10-30-2013, 12:53 PM

I wouldn't go any lower than this with 15" wheels...it's very close!

71 GMC 1500 with 2.5 CPP Spindles, 1" CCP Spring, DJM Flip Kit 5" FK1012-5 for 2.25" leaf spring. Supposedly 3.5/5 more like a 4/6. 20x8 OldSkool with 275/45 Falken Ziex TZ04. The front has settled a little more since these pics after doing the ball joints and getting the springs seated properly.

beautiful truck, interested on knowing what set up you got to get the 6-8. first time i've come across that set up. i was under the impression that anything after 5-7 needed to be bagged. thanks.

Roger71SWB · 11-04-2013, 01:54 PM

I have 20x8 front and rear. Rear is 6" spring with 2" block

ksshane · 10-30-2013, 06:30 PM

I haven't got to that point yet of seeing if 20's would fit, but I dont see any reason they wouldn't. only thing i would have to take into consideration is tire sizes for front and rear.
