on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | I read somewhere there was two different front axles on the 1.5 ton a light duty and a heavy duty like the 2 ton. My question is I have a 51 4400 was a dump truck wondering if it had the heavy duty under it? Would like to do a disc brake conversion what would be the easiest?

Some really good info and certainly a good choice when it comes to bigger brakes. Also please check out my option. https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=964265&page=1Long story short is that I have made a bolt on caliper bracket and hub adapter as well as a bolt on master bracket that uses a vacuum boosted M/C from a 3500HD Chevy. Good luck with your truck. Any pictures? | | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | Pics im still trying to figure out how to post them

Not that it matters, you have the 2 ton axle and can swap spindles and brakes if you want.
Grigg | | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | The number on the title from the vin buster says its a 4400 no plate on the truck , the little box of parts I have 4400 emblems and the wheel base is 137 I quickly threw a tape on it which puzzles me too. Is there any other way to tell? If not ill have a unique 4400 that only u guys will know. Its good to know I have the 2 ton front axle and can do the brakes as u described.

Another option is the frame was shortened, any welds in it? Looks like you have a single speed rear axle which is most common in the 1.5 ton, so I'd lean toward a 4100. To confirm or deny look up the frame height and thickness specifications and compare to the 1.5 and 2 ton 137" wheelbase trucks. I thought it was in my shop manual for 48-52 and it may be, but I couldn't find it in the 48-51 manual here http://chevy.oldcarmanualproject.com/ might be in another manual or book on that site.

Shortening the end of the frame for a dump bed is very common but doesn't change wheelbase.
Grigg | | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | It does look like the frame was shortend on the tall part of the frame right behind the cab. There is a two foot plate bolted to the inside of the frame on each side. Looks like a good weld ill try to take a couple pics tomorrow
Makes me wonder what the history of this truck really is
