Lowering my 1970 C20
 

I am new to the board and have really enjoyed looking at everyones builds and the wealth of information found here. I am just starting a build on this truck and one of the first things I would like to address is lowering & converting to 5x5 lug and front Disc. I am hoping to drop front 5 1/2 " and possibly 7" in Rear.

I have some questions maybe you all could help me with:

Can I use a C10 Drop spindle kit on a C20?

What would be best way to achieve this drop?


Suggestions? Advice?

Thank you in advance for any and all help. :)

I agree on the pics, but unfortunately I live in Maine and we have had 127" of snow this year! Preparing for spring ;) Sorry didnt see suspension thread.

Re: Lowering my 1970 C20
 

I went with a 6 inch rear drop and 4 inch front drop. Used two inch lowering blocks and four inch shorter springs on the rear along with a bent pan hard bard for clearance and a c notch. The front was 2.5 inch drop spindle and 1.5 inch shorter spring.

snow? what is that.... lol we had a pretty cold morning this morning, got down to blustery 34*, burrrrr

Re: Lowering my 1970 C20
 

Did you use a C10 Drop Spindle? Did you convert your Bolt Pattern to 5 lug?

Re: Lowering my 1970 C20
 

No 5 lug for me yet. I have 5/3 lowering so far. I used springs from GMC Paul's, relocated shocks and trac bar from CPP. Good luck!!!

Thanks I did post there after first response suggested it. No replies there yet.

Re: Lowering my 1970 C20
 

As I commented in your other thread, ECE is the only company that will let you keep all the rest of your suspension stuff and run 5 lug brakes with their spindle.

Scroll down here and see the C20-C10 spindle.

Just wondering if I can use C10 spindles on a C20? Are they that different?

Was also looking at the possibility of:

Doesn't mcgaughy have a 63-70 drop/stock spindle 5x5 and 6x5 setup? I just bought the 6x5 for my 68

Tree-50, thank you so much for the links and tips. If I can figure out if I can use C-10 spindles on a C-20 I'll be ready to go! lol

Rodzilla67,

Lots of info on front changeout.

What is your plan on converting the rear end to 5 bolt?

Re: Lowering my 1970 C20
 

I planned on changing the axles. I assume this is a reasonable method? Also still wondering if I can use c10 spindles on a c20?

Re: Lowering my 1970 C20
 

Yes and No.
3/4 ton lower a--arms have a larger balljoint hole.
You will need 1/2 ton lower a-arms and you will have to switch to 1/2 ton balljoints and outer tie rods.
Simpler choice is to use the "3/4 to 1/2 ton CONVERSION spindles" offered by ECE.

Re: Lowering my 1970 C20
 

C20 spindles are TOTALLY DIFFERENT than the C10 version

Ty Lolife. Awesome info!

Re: Lowering my 1970 C20
 

Where did you find the 2-inch lowering blocks and did they come as a kit with the longer u-bolts? :chevy:

Re: Lowering my 1970 C20
 

Just use google man not that hard

Here's a couple good threads to look at.
Member way2lo2 is a good source for lowering blocks and u-bolts.

Re: Lowering my 1970 C20
 

I got mine from CPP. They did include the longer U bolts and nuts.
