How Low can I go... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

FlatBrokeRacing · 06-01-2007, 09:57 AM

I should know this already but mainly want to get your knowledge passed to me.

1980 GMC Stepside. I want to know how much I can safely cut the front coils and front bump stops before it starts riding like a goat wagon. I was given some shackles for the rear a while back (they are now installed) and just want to set the front down about the same amount. 2inches.
Thanks in advance for any help...

don't cut more than 2 coils off. I would try 1.5 coils first

Thanks CaptKaos,
I thought I could go two rounds but wasn't sure. I might just stick to one and a half.

This how my front sits with 2 cut coils, 1 cut coil is a 2" drop depending on the spring, correct me if i'm wrong but shouldn't the coils be cut as whole coils in order to sit in the spring pockets on the A-arms

Hm, cutting springs?

I have experience with this on a 91 Camaro... cut 1.5 coils to lower it and after a year or so the car sagged and bottomed out.

The right way was to buy uncut springs that provide the desired lower ride height. Luckily Eibach made some...

Cut 1 coil off & see how much drop you get. It's easier to go back & trim a little more off (& you can't add back on if 1.5 coils are too much).

Were the springs on the 91 progressive? You can't cut progressive springs.

Thanks for everybody's in put. I did a ststic slamm on an old 82 LBF that I had in highschool. (Found out the hard way how not to do it)

I am going to tend to agree on full coils at a time for proper seating.

Malo83,
That is a smooth look you got going there.

I will post some pics of mine as I am doing the front...The rear already has 2in shackles and I have yet to flip the rear. Either way, It will be a road hugger.
Thanks everybody
