Approx how much drop do you get when cutting 1 full coil out of a stock v-8 non-air 2wd front coil?

Re: old school drop question...?

It depends on the condition of the springs but between 2-3 inches has been my experience.

Re: old school drop question...?

for less than 125 bucks delivered you can get new drop springs that will take the guess work out of it. Just my .02 though. I just did drop springs and it was worth the money.

Replacement springs are todays "correct" way to do it.....BUT...$125 is not always in the budget and 2-3-4-5 inch drop springs dont always give you 2-3-4-5 inches of drop from your starting stance due to sagging original springs. Every set of drop springs I have bought I either had to cut or TRY to send back to obtain the correct drop I was looking for!!! With that said...cutting your stock springs sounds like a fine idea.

Re: old school drop question...?

The speed shop I work at, we sell all the Belltech, ECE, AIM Industries drop companies. This truck I'm building is a budget build. I'm looking for somewhere about a 2" or 3" front drop. So, I'm going to just cut the stock coils in the truck. I have 2-1/2" drop spindles, but sometimes with spindles a 15" aftermarket rim will hit the lower control arm. So, I'll save them for my next build.
So, this truck will be a cut coil in the front and new ECE 5" rear drop coil.
So, Thanks everyone for your replies.

They take the guess work out of it only if their measurements for drop are based on your current ride height. The common problem is most drop springs have the amount of 'drop' calculated vs. the original ride height. The amount of spring sag will vary per truck over 35yrs of use.

I always cut a coil first off of the installed OE springs to see how it goes & would agree that you typically net 2-3" of drop. It's free & you can see if it's what you want. With only one coil cut, I've yet to have a truck that still didn't ride decent (I would not cut more than one coil).


Bryan, what size front wheel are we talking about? I run van ralleys (15x6.5") w/3" B.Tech spindles on my 74 & it only required minimal trimming of the lower a-arm lip. I used the same wheels on my 68 w/2.5" Western Chassis spindles & did not have to clearance the a-arms @ all.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

I like the wheel choice. Who is the manufacturer?

If your builds are anything like mine have been..... use the spindles now (before they become obsolete ).

I think (If my memory is correct) it's a compamy called Majestic (China made) I bought a set of 4 15 x 8's from a local tire shop, then ordered 2 15 x 7's on ebay from the same supplier. Only come in limited sizes and a set B.Spacing. I will look to find you a link...

EDIT...
I bought from this guy..
