67-72 coil rear owners....

[screamin_c102]

Those of you with lowering blocks in the rear, where did you get the longer single monster u-bolt to hold it together? I ordered blocks for the rear of Screamin' and they came with the typical two u-bolt per block setup.

Did you have them made? I have 2" blocks, do you think there is enough thread on the factory bolts to get a 2" block in there safely?

Next question:
I have bags in the front and rear, I want to add 2" blocks as well, do I need a notch?

Could somebody post a pic of one of our trucks with spindles, blocks, and bags with no notch?

Thanks.....Bill

I buy them at my local spring shop.

Look in the yellow pages under truck spring shops. You'll know you found the right place when you see big busses and Peterbilts in their parking lot.

Last set I had made was just under 30 for a pair. Take one of your stock ones in there so they will know what to make, and tell them how much longer you need them to be.

W/O a notch, you won't realize the full potential of your combination. This pic of my truck is @ ride height w/2.5" spindles, rear bags, lowering blocks & a c-notch. W/O a c-notch in place, you wouldn't be able to get this low in back & still drive it....

I got my lowering blocks and u-bolts from Classic Performance Products. Check them out also if you don't have anything local. They're very affordable and I was happy with the product and service I got from them. I'm w/ SCOTI on the notch. You're gonna need it if you're bagged out back. There's really no point of bagging it out back if you don't at least c-notch. That's like going in to the best steakhouse in town and ordering a salad.

On a side note, if the blocks came with 4 u-bolts they're for leaf applications and you shouldn't use them on your truck.

[screamin_c102]

Scoti, do you have a pic of that truck aired out?

smbrouss70, Why would that make any difference? Are they built differently? If you look at the trailing arm perch on our truck's rearend, it looks just like a leaf spring perch. I guess I could sh!t can these and order a complete setup from CPP or somebody.

I would look pretty stupid asking for drop blocks for a coil application

[smbrouss70]

The leaf spring blocks will have a center pin to hold the rearend from sliding on the leaves, on the bottom there will be a recess for the same style pin on the leaf spring itself to hold the block in place. Usually these blocks don't have much material where the big single u-bolt would go on our trucks, which if you drilled through it for our style u-bolts, there wouldn't be enough material to properly locate the block. I used that style block years ago (when I was young & invincible), before there were so many aftermarket companies that made everything you could want for our trucks.

I made my own set of lowering blocks by cutting up some 2x2 1/4" wall square tubing and getting a set of u-bolts made like mentioned above.

Thank you, I greatly appreciate the info and advice. I thought about making my own, but the lazy bug bit me.

I will call CPP as soon as I get some funds together, and order their kit.

Sorry, no 'aired-out' pics.
But.... it doesn't get much lower than in that pic because the 'pumpkin' hits the bed floor.

I keep as low as it will go under normal, daily-driving circumstances & air it up for a little extra clearance when I have the car trailer hooked up & loaded.

Here are a couple of pics of my set so far.This is without any blocking and the axle uses the entire notch (with the bed on and aired out there is 3/16" of space left in the notch(not a real clear pic of it sorry).The other pic is with the bed on and aired out just to give an idea.

[screamin_c102]

The way I was looking at it is, with 2" blocks I could remain low, and still be able to run a little higher pressure in the bags for a better ride. I currently have no notch and no blocks and when aired out I am on the frame, and my bags are extremely collapsed. If I were to run blocks they would lower my trailing arms on the axle allowing my bags to inflate a little more before lifting the frame from the axle tube. Does this make any sense or am I going

Don't get me wrong I will notch her soon, but I have way too many irons in the fire.

Thanks for all the advice so far......Bill

[SCOTI]

Yes, a little more air in the bags will help the ride quality (within reason). My truck typically is @ 30psi of pressure @ ride height. If I bumped it up to 40psi, it has a nicer ride. But if you go extreme (say up to 60psi) w/no load, it starts to ride kind of harsh.

[screamin_c102]

Thanks Scoti, you hit it right on the head I was starting to confuse myself on that last post.

Cool, as soon as the floods stop and Noah parks his Ark, I'll be puttin' in blocks and spindles.
