Front suspension drop failure - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have 2 1/2" drop spindles and cut 2 full coils off the stock C/10 springs. Truck is fully bottomed out with tires resting on the top of the inner fenders. Clearly 2 coils is way too much. Time for new springs.

You shouldn't be cutting coil springs to begin with.

kalbert · 10-11-2015, 11:07 AM

Nah... Cutting springs is fine. Do it with a sawzall or cutoff wheel, not a torch and you'll be fine. 2 full coils is pretty aggressive, most people do just one and get around 2" of ride height with a moderately stiffer ride. Chopping a coil off and relocating the shackles and hangers is a near zero cost way to get lower.

Burmanater · 10-11-2015, 12:03 PM

You might want to try a smaller size tire. That's the way my truck sits and ive got a 225/70 15 and it still rubs on hard cornering. had a set of 225 75 15s up front and it was about the same but rubbed a tad more(Hercules terra trac) I had 225 75 bfg ta tires that for some reason didn't rub though.

SkinnyG · 10-11-2015, 12:29 PM

If you're buying springs, buy 1-ton springs. It adds spring rate so you can ride low with less bottoming out --- but only cut a coil or so off (I cut a coil, then kept trimming 2" off the end until it sat at the height I wanted).

1 coil on stock springs is a 2" drop. You cut a tad to much lol

Major86 · 10-11-2015, 03:55 PM

How much drop is 1 coil off drop springs? 2" as well?

muthstryker · 10-11-2015, 04:39 PM

Probably 1", drop springs have more coils with a higher spring rate.

65standard · 10-11-2015, 06:02 PM

Thanks everyone. I just bought the Moog 6454 springs from SummitRacing. Couldn't beat the price, $8.97 a pair plus shipping. Must be a mistake, but I bought them before they see it. The cheapest Moog 6452 springs I found are $69. One-ton springs it is.

Holy OOPS Batman ... I ordered a set too and I don't even need them right now... I though you had a typo in your post till I checked out the site...

RUN GMC · 10-12-2015, 02:14 AM

In for a set just because........thanks for the heads up.............

school boy · 10-12-2015, 09:39 AM

Bought a set myself! $15 shipped is a steal! Glad I looked into this!

Joe69C10 · 10-12-2015, 10:48 AM

Great deal! I just ordered a set for $14.92 shipped! Im in the process of dropping my truck and was gonna cut the old rusty stockers..

Domer · 10-12-2015, 12:28 PM

all you people ordering them.. now they show ship today, but when you check out, they say back ordered with an estimated ship date of Nov. 5

65standard · 10-12-2015, 03:39 PM

They had 10 pairs available when I ordered mine.

ddr11 · 10-12-2015, 03:40 PM

There is a easier and cheaper fix for this. I've been running this set up for a while now. AFCO makes a coil spring spacer/adjuster for the dirt track application. This also works very well when your truck doesn't sit level across the front

Tom · 10-12-2015, 05:31 PM

^ Thats a good find, something to remember for down the road when needed.

Mine are scheduled to arrive today on the 13th.....

Shugalou · 10-13-2015, 09:10 AM

damn they are still there

http://www.summitracing.com/int/parts/mog-6454

I thought about buying but I would prefer a drop spring - damn good price though

solidaxel · 10-13-2015, 11:42 AM

I could not resist!
I need to change one spring, front end is sitting 3/4" lower on the passenger side, so I guess I will change two at that price!

When you receive them would you check the static height (length), Thanks

65standard · 10-13-2015, 07:35 PM

Mine were delivered today.

gasmn1620 · 10-14-2015, 08:43 AM
