New to the C10 game, need advice on a rear drop - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Poop du Jour · 05-17-2017, 01:55 PM

Just picked up a 78 C15 and I'm itching to drop it on its face but I see that the previous owner removed all but 4 leaves from the rear spring pack. It's also still above the axle. The goal for this is to keep it super cheap and ride it dirty so my question is this: flip kit or drop shackles?

5-6" further drop seems like it might be too low but 2" might not be enough. Front coils will get cut down too. It needs to be as low as possible, I don't care about ride quality.

Thanks y'all!

aggie91 · 05-17-2017, 02:30 PM

If you want it low, then flip the rear. Use a drop spindle and a cut spring in the front. Some of these trucks only had 4 or 5 leaves in the spring pack from the factory.

Jstock85 · 05-17-2017, 05:15 PM

cutting one coil should give you about a 2" drop. other guys can tell you for sure

bbbc10 · 05-17-2017, 09:29 PM

If you dont care how it rides just heat the front and rear springs ��

Jaysonb · 05-17-2017, 11:17 PM

Nice looking truck! I like the color combo.

DON'T do a hack job like cutting coils or heating the springs...... if you're gonna do it, do it right. It's cheap to lower one of these so why do a hack job ???

Please dont recommend heating coils. Some people might take your serious and not know its a terrible plan.

Heating coils is a hack job, cutting coils is not. In fact a cut C10 or C20 coil rides better than most aftermarket lowering springs.

Cut coils in the front, relocated spring hangers in the rear. Total cost was $1.38 for bolts and a front end alignment.

250,000 and 30 years as a daily driver with no issues.

Thats my kind of mod$$$ Cutting coils is no problem. What or how did you relocate the hangers? Would you mind sharing a few pictures?

Keith Seymore · 05-18-2017, 12:48 PM

You have to cut the rivets (somewhat labor intensive) and replace them with 3/8" Grade 8 bolts.

If you go this route I can talk you through it.

Hey Karl. I'm good. I've been creeping your thread over on LS1Tech for a long time now. I hope you can make it to C10s in the Park this year.

I'm on board with Specialty Retail's brackets. Inexpensive and they work just fine.

You figured it out.

One guy is nice and kind. The other one has a curious eye twitch and mutters ugly things under his breath.

Come find me at Decatur swap meet this fall and shake my hand.

Yep, pretty much figured it out during your answering of one of my pm's, but I wasn't 100% sure and kept my mouth shut. The instagram id is a bit of a dead-horse giveaway though.

I'll see you there.

Jstock85 · 05-18-2017, 01:17 PM

yeah i def plan on doing that. Did you have to replace the shocks afterward?

Keith Seymore · 05-18-2017, 01:54 PM

No.

Jstock85 · 05-19-2017, 12:04 AM

i think ill give keith's method a shot first. lower my truck for $1.38! gotta be worth a shot

KQQL IT · 05-19-2017, 01:50 AM

Several dollar's in bolts some $20 axle pads.
And a few hours

Clipped 2 coils, cut bump pads off the lower A-arm and rear frame.
Flipped the back.
Longer bolts in the upper A-arm

How we did it before we knew about drop spindles.

Still rolling this way today.

Jstock85 · 05-19-2017, 07:47 AM

Im glad you guys shared this info. I knew there had to be a better way to get low than theses $500-$600 "lowering kits"

Tx Firefighter · 05-19-2017, 12:13 PM

Thanks Keith.

The wheel and tire setup is about to be switched out honestly. It doesn't drive the way I want it with the 215/75 235/75 combo. The fitment isn't exactly what I want either.

You're a perceptive guy. I'd bet money you can guess what's in the boxes.

**lolife99** · 05-19-2017, 12:37 PM

Looks like you are switching to another classic design,...
