Re: lowering question
No C-Notch needed but you may consider a Super Track Bar and a Shock Relocator Kit (both of which I bought from ECE). Currently, I'm running with a 3/6 Spring Drop. Good Luck

Re: lowering question
no you do not need a c-notch...I am running a 4/6 ECE drop on mine...
I agree about the shock relocator kit and the super track-bar.

Re: lowering question
As several have posted, a c-notch will not be "required" on a 3/5 or even a 4.5/6 drop. However, if you plan on hauling things in the back of your truck (wood, scrap, etc.) you will probably bottom out more since you are closer to the frame. A c-notch will give you the added space if you intend to haul items with your truck.
So far for my setup (4.5/6) I have yet to bottom out.

Re: lowering question
Then it sounds similar to my truck. It ocassionaly hauls some coolers, a canopy tent, and a BBQ. Everything else is hauled in my DD.
Good luck with the install, and I would highly recommend ECE (Early Classic Enterprises).

Re: lowering question
I am running the KYB drop shocks offered by ECE w/ shock relocators. Smooth/clean ride.

Re: lowering question
do the shocks lower any or just give it a better ride with the springs?

Re: lowering question
The shocks themselves don't lower the vehicle, they however work with the lowered springs and the suspension geometry to keep it as close to factory spec as possible. If you attempted to retain OE shock mounts the shock would sit to flat, and if you attempted to use OE shocks w/ shock relocators they would be either to long or to short (sorry I'm not sure which on, but I know they wouldn't work)

Re: lowering question
Contact the guy's at ECE (Stan/Mark) and they will set you on the right path. Their parts might have a higher price tag than CPP but with the remarkable customer service, and technical support, you will not regret buying from them. I have not ordered from CPP but several on the board have and have been left waiting parts for several weeks, if not months.

Re: lowering question
its a good idea to get shocks because i didnt do it on mine and it rides like total crap. its a very stiff ride and if you hit a pothole in the front, it sounds like something is breaking...... its worth the extra money.

Can someone post a picture of the shock re-locaters? I'd like to see the difference and how they mount.
Thanks, s/t

Re: lowering question
s/t, the shock relocators actually utilitze the same mounting holes as the originals, they are just change the mounting locations.

Re: lowering question
Here's the best I can do guy's.... like I mentioned above, they're not really "relocated" they just change the mounting point for the shock not the bracket.
The old mounts (first 2 pics): The new mounts (last 2 pics):

Re: lowering question
Is 3" on the front the lowest a guy can go without the spring being sloppy in the housing? IIRC someone said there spring was sloppy when the had there truck jacked up but I can't recall what spring that was.

Re: lowering question
69GMCor70Chevy, I believe you are correct. Front 3" drop springs have the tendency to come out of the bucket when the front of the truck is jacked up.

Re: lowering question
Wouldn't it be better to use a 2 inch drop spindle and a 1 or 2 inch drop spring in the front?
