What I'd like to find out is what we can change on the front end ( and with what?) to get the truck in the weeds. I know that there is aftermart stuff out there, but we'd like to start with a 1/2 ton setup. We have built street rods (cars) before, this will be our first truck. I have tried to do a search here ,but could'nt come up with anything for our year truck. THANKS Joe K | | | | | Joined: Jul 2005 Posts: 227 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 227 | I would recommend going with a disc brake with drop spindle kit. upgrade to 73-87 balljoints and tie rods. then throw in drop springs while youre at it. check out http://www.earlyclassic.com/tech.aspx?category=Stance%20Photos-2 for stance photos but look around for cheaper kits. not sure about rear suspension on c20s but whether leaf or coil there are many easy options to lower it. | | | | | Joined: Aug 2006 Posts: 3 Junior Member | | Junior Member Joined: Aug 2006 Posts: 3 | Thanks for the quick reply,We're planing on using dropped spindles,but I don't quite follow what you're saying. Can we only change the ball joints and tie rods and then be able to install 1/2 ton dropped spindles or do we have to change the A arms also.Thanks Joe K | | | | | Joined: Aug 2004 Posts: 1,067 Shop Shark | | Shop Shark Joined: Aug 2004 Posts: 1,067 | You can get a dropped spindle kit.
Contact Speedway, they might have something.

I saw it written up in one of the truck magazines sometime in the last couple of years.
I would expect you would just swap the complete crossmember with disks from a '72 to '87 1/2-ton and you might even find one that already has the dropped spindles.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Aug 2006 Posts: 3 Junior Member | | Junior Member Joined: Aug 2006 Posts: 3 | Well can anybody second any of the above opions? Can we only change ball joints,and add 1/2 ton spindles or can we put in a complete 1/2 ton crossmember from a later model truck??? THANKS Joe K | | | | | Joined: Jul 2006 Posts: 187 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 187 | Classic Performance Products now makes a spindle (drop or standard)for 3/4 ton trucks. It's availible with a 5 or 6 lug pattern. I have a 1963 C20 and have been researching ways to drop it and convert to discs. This seems like the simplest and economical way to git'r done | | |
