EastBay521 Posted October 17, 2014 Report Share Posted October 17, 2014 I believe 320 on up were all h-190 axles which I believe DMike says is good for 300hp. some one correct me if im wrong Quote Link to comment
datzenmike Posted October 18, 2014 Report Share Posted October 18, 2014 All 620s were rated at 500Kg or 1,100 pounds. There were no one ton trucks although there were camper and heavy duty optional springs for them. These will probably carry more weight without sagging but the truck is still rated at 500Kg for licensing so don't go over and get caught carrying a ton and a half of gravel or you'll be yanked off the road real quick.. The 521 with the J13 engine L520 and the '69 L521 were rated at 1,000Kg or 2,200 pounds but the later '70 and on PL521 with the L16 engine were back to 500Kg payload although I believe they kept and used the same leaf springs. The 720 Heavy Duty (single rim) truck was rated at 770Kg (1,700lbs) through '82.5 and only 500Kg after. All '82.5 Heavy Duty dual rim trucks were rated at 770 Kg. All these trucks used the H-190 rear ends. Quote Link to comment
