how low of rear coil springs can i go without c notching the frame? 2 3 4 or 5 inches? 1968 c 10

**uncle** · 05-16-2007, 10:01 PM

I've gone as low as 7". Depends on what you use it for.

**Smitty** · 05-16-2007, 11:20 PM

I've got 6", but found out you don't use the truck to haul much because they can't handle a lot of weight. Not that I use it for a work truck.

I believe you can go 6" without a notch.

harleyx2 · 05-17-2007, 07:09 AM

was just wondering because the lmc book shows you need to notch with a 5 inch drop

centsless · 05-17-2007, 07:37 AM

I have 5" rear lowering springs on mine with no problems. I also installed a ECE super track bar kit, but that was to clear my exhaust.

**Tom Vogel** · 05-17-2007, 10:34 AM

That ECE track bar also eliminates the bump steer you would otherwise get from a 5or6" rear drop. By the way, after having bags, I would never go back to springs. Bags are completely adjustable for height regardless of weight. As for the notch... at 6"... I dont think its needed (I didnt), unless you plan to haul ass over whoops.

no offense, but first thing is ditch the LMC mag

PanelDeland · 05-17-2007, 06:22 PM

yellow,I can't believe you're telling someone to ditch the best pictorial assembly manual made for these trucks.You should just tell him to order from someone who doesn't think old truck parts are gold.

5150 · 05-17-2007, 06:29 PM

true deland, it is a good pictorial, but that's about it

jsbgump · 05-17-2007, 06:40 PM

6 in is as low as you can go without a notch

hiridn69gmc · 05-17-2007, 08:36 PM

I have a five in mine and love the ride quality. The PO had the springs torched to where I would estimate about a 7 w/o a notch. The ride was horrible with the torched springs and bumpstops got in the way quite a bit, so I don't know if it would've hit without them or not....No problems at all with the 5 though.

hey i just ordered some rear drop coils for performance online and the tech said 4 inches is as low you can go without having to c notch. but i have not installed it yet.

faribran · 05-18-2007, 05:07 PM

what did u guys do about the bump stops?

see ten · 05-18-2007, 05:28 PM

I have ECE 6" rear drop coils and the super track bar. She's fine in all but the harshest conditions. However I drive it like I stole it! If you tend to ease over every railroad crossing and speed hump you are going to be fine with this setup. Loaded, things are a different story. On the way to Maggie Valley I had a 50qt cooler loaded down in the back along with our luggage and folding chairs and my box of cleaning supplies. I could feel the difference of having this small of a load in the back. I also bottomed out several times on the way up. I have no bumpstops whatsoever. If you plan on hauling a load you're probably going to be happier with 5" springs or bags. Here's mine.

This truck has 5" drop coils out back.
