Best riding rear suspension set up.
I have a 68 C10 with rear coil suspension. It has 5 inch drop springs from ccp and they are soft as butter. If someone sits on the tail gate it will almost bottom out! Whats a good spring for handling that has a little drop to it? The front just has 2 and 1/2 drop from the lowering spindles. Also it seems I need Rear Shock Relocator from no limit. I already have no limits panhard bar kit installed. Would it be better to use lowering blocks?

Re: Best riding rear suspension set up.
I also have the rear CPP 5" springs in mine. Same result as you....pretty spongy. I'm gonna watch this thread and see what comes outta it. I've too been wondering about a stiffer spring with same amount of drop.?!

Re: Best riding rear suspension set up.
Get yourself some load bags. They are in my signature. They work great and you can adjust them for the right ride. Yes the No limit shock kit is a great addition as well. I have both and my 71 drives great.

Re: Best riding rear suspension set up.
I have no first hand experience with this yet but I've done a lot of reading on it since I'm putting trailing arms under my 78. I saw a lot of people recommending to get the first 1.5-2" of drop from a block to keep the spring as long as possible for a better ride. So if you wanted a 5" drop then a 2" block an a 3" drop spring should yeild a better ride.
Again just something I've seen recommended over an over on this forum.....

Re: Best riding rear suspension set up.
What spring and block is recomened? Ive read allot of the same posts saying to static drop them that way, but never any specific parts info... ive also heard.that pb trailing arms have 3" drop built in, so would those.with a.2" spring be ideal?

Re: Best riding rear suspension set up.
You might also contacting GMC Paul's (board vendor) they do custom rear springs in a variety of rates. I have no idea what the spring rates are on the CPP springs, I tried to find out the spring rate of the 2" drop front springs I got from them and never got an answer, so I ordered my rear springs from GMC Paul's to make sure I got what I wanted.

Re: Best riding rear suspension set up.
Trailing arm rear suspension, relocated adjustable coilovers, or a good shock and a 7" bag.
Honestly, on the trailing arm rear, a good shock and a halfway decent spring rides better than prob 90% of the leaf spring trucks here.

Re: Best riding rear suspension set up.
I am one who doesn't like the rear blocks. If u do run them make sure the wheel is big enough so that the u bolts don't stick below the wheel. Blocks in my opinion are for a cheap lowering kit.
Getting a good spring is the key. The No limit shock relocator kit are some one elses kit is a must have. Having the shock perform as they are intended to do is key also.

Re: Best riding rear suspension set up.
Well I have the shock relocater kit coming in from no limit. Can my stock shocks be used? They are new. I will eventually put bilstein shocks on all 4 corners. I noticed my pan hard par was contacting the rear exhaust and would limit travel. That is now fixed.

Re: Best riding rear suspension set up.
My plan on the advice of a few people I've talked to is to go with ECE springs as they aren't near as spongy.
I already have the CPP 4 wheel disk conversion so I'd like to stick with their DS and other components. If you're willing to drop a few bucks on the ECE springs it may solve the sagging rear. |

Re: Best riding rear suspension set up.
Hi Vannatta20, my 68 c10 is equipped with 2 1/2" dropped spindles in front, and 4" ECE brand coils in the rear. I have hauled 1,000lbs many times doing home improvements projects and on rare occassions it bottoms out. The best changes i made in the rear for a better controlled ride were, shock relocaters, and installing a porterbuilt panhard bar. I have been using monroe sensa-trac shocks and can say they work pretty good. Before the changes with the 4" lower springs already installed the rear would bob up and down too much, but rides great now. Good luck, Brian Fuller

Re: Best riding rear suspension set up.
I think you're going to be surprised at how much of a difference the shock relocators make. Right now, your shocks are at such an angle that they aren't very effective. Standing the shocks back up to the right angle will make a big difference on ride and handling.

Re: Best riding rear suspension set up.
I don't think your stock shocks will work, if I recall the stock shocks are shorter than the ones that No Limit uses. I'll try to get the # off of mine over the weekend which will allow you to cross reference.

Re: Best riding rear suspension set up.
I hope I don't run into this; I have a cpp big slam kit with 2.5/4" drop on the way. Also ordered the shock relocators and and adjustable panhard bar.

Re: Best riding rear suspension set up.
I agree the stock shocks may not be long enough to work with the No limit kit. I bought all of it together. They move the shocks out ward and further back on the frame to make a much better ride and handling.

Re: Best riding rear suspension set up.
The no limit shock kit sure does lower the scrubb line. Must need a 17" rim of bigger to be safe

Re: Best riding rear suspension set up.
Good point! The no limit kit looks like it lowers the scrub line. I have also noticed i haven't seen any pictures of the no limit kit installed with a hitch kit. I am looking to install a shock re locator kit and a CPP hidden hitch kit. The CPP hitch kit runs up the side of the frame. Would it interfere where the no limit bracket mounts. Has anyone tried this combination?

Re: Best riding rear suspension set up.
I was told via email to No Limit that a 15 inch wheel could be safely used. I have yet to purchase this kit. Anybody know of anybody who has ran a 15 inch wheel?

Re: Best riding rear suspension set up.
A softer spring will let the rear float a bit more, and prevent it from being bouncy over washboard roads and things like that...but it will also have a tendency to roll/lean more.
A stiffer combo will corner and handle flatter/better, but will feel harsher. This is most common with dropped trucks where the spring has to be stiff to carry the weight of the truck. Better shocks/adjustable shocks help and give you some more leeway with controlling the weight as well. Its usually a good idea to upgrade both systems at once, otherwise you may not be taking full advantage of either upgrade. I really like some of the variable rate springs for trucks, which allow a softer spring that stiffens at the bottom 1/3 to still offer an improved response.
