Trying to figure out how my 68 C10 was lowered
 

The back end of my truck is very bouncy. Just putting one foot on the bumper and pushing lightly, the truck just bounces up and down like jello. The front looks like it has stock spindles on it, and the rear looks uniformly dirty and rusty. Do you guys see how this thing was lowered? Did the PO just cut the coils on all 4 corners? Thanks in advance.

From what I can see I think the springs have been repaced the rear dont look stock and is the truck bounces I'd be replacing the shocks they are supposed to absorb enery and stop the bouncing.

Does someone need to resize pics? :lol:

Re: Trying to figure out how my 68 C10 was lowered
 

You need rear shock relocators and drop shock to fix the angle of your rear shock. They aren't working like that.
Also need an adjustable panhard bar to Re-center the rearend.
I bet you have a 3/5 drop with springs only.
That's only half of the stuff you need to make it ride good. Drop spindles are needed if you want to go lower.

Yup, he's only getting a little bit of stroke with the shocks mounted at that angle, so not a lot of damping action, there.

....those are damn big pics.

Sorry for the big pics, didn't know they would be as big as they are.

So in order to have a truck that rides well, and I'm not afraid to load it with crap, what is the best method? Rear shock relocators make sense, but that wouldn't really help with such a soft suspension, would it? I thought that if the vehicle bounces more than once, that was the shock. But if the car was very spongy and bouncy, that was the coils.

If i were to get the CPP 3/5 drop coil kit, with the shock relocator kit, pan hard bar, and coils/shocks, that wouldn't make it any lower than it already is, right? I'm thinking that if I did that, I would have a truck and handles better and have known components. Plus, they're shiny and clean, which is always nice too :cool::cool:

The 3/5 kit may actually raise you up just a tad. But idk. Those springs look like they have been heated before.

Re: Trying to figure out how my 68 C10 was lowered
 

I bet those are already 3/5 springs.
Probably CPP because everyone buys there junk based on price.
You might as well take those rear shocks off. They aren't doing anything but pivoting on the bolts.
Call ECE. www.earlyclassic.com
Also search reviews for CPP and ECE.
You will be surprised how far apart they are on the review scale.

Re: Trying to figure out how my 68 C10 was lowered
 

Your shocks appear to currently be in an almost horizontal position. Shocks are not designed to function in that position which means you are basically riding on the rear springs hence the bouncing. The shock relocator brackets allow the shocks to be moved to a more correct vertical/upright position so they can function as designed.

Here are the two relevant pics resized for better viewing...

Your rear shocks need to be both replaced and relocated for correct angle...
kits are available from several vendors...you may also need shorter shocks so they dont bottom out in compression.

You will also need an adjustable track bar to re-position the rear axle on tha chassis center line.

You have little rear axle travel left...you may have a c section your chassis if you want more travel or go lower.

The front has less than an inch of travel until bump stop bottoms out...suggest dropped spindles if you want to go lower...some folk cut the bump stops in half to give more travel...

I've been wanting to look at the pics since last night, but I'm still waiting for them to finish loading

Sorry about the pic sizes, still gotta figure that part out. I appreciate the replies, and the info about the shocks and the track bar. I just ordered the adjustable track bar and the shock re-locator kits from ECE. Once they're on and installed, I'll see how it rides, and go from there.

At this point, I'm really thinking about doing rear air bags, since I do use this truck regularly to make dump runs and stuff. One of the vendors has a kit for 2 Dominator 2600 bags + brackets for $244. It'd be nice to be able to pump up the rear when I'm hauling stuff. I haven't noticed it bottom out yet, even when loaded with crap, but it does feel pretty washy. I know that without bags, I'll never have a low truck that maintains capacity to haul and tow as much as a stock height truck, especially one with HD springs.
