67 3/4 ton to 1 ton conversion

[YETTI67]

ive heard that and 85ish model 1 ton front end will bolt to a 67 3/4 ton chassis. just wondering if this is true. looking at converting to one ton front end.

if you are looking for the upgrade to achieve disc brakes, you can upgrade to 71/72 one ton suspension and do the same within the same suspension and body style..this would also in able you to add a heavier duty sway bar and power steering!

Youll probably be dollars and sense ahead if you hunt for an entire 74-87 (bit later on the burbs) 1 ton frontend assembly (crossmember, A-arms, spindles, rotors, calipers etc), and bolt it under your 67. The JL8 option began on the 1 tons in 74 (not sure why not 73) giving you the bigger 1.50" thick rotors and 3 1/8" diam. piston calipers. These square bodies also had the bigger 1.25" diam sway bars. 74-77 was SAE thread fasteners, afterwhich they adopted metric ..not a big deal breaker either way, the wheel studs remained SAE. 1 ton 2WD Dually trucks (DRW) were, and still are, more plentiful than 1 ton 2WD single rear wheel (SRW) trucks, and they used the same front spindles, calipers and all as the SRW - only the rotor itself was different. Probably a bit easier to still find a square body setup over a 72 and earlier setup too, since there were a heap-load more of them built. Happy hunting


PS. The 1 ton SRW trucks in the square body years could be optioned with the "big boy" JL8 equipment, but most had the standard JL7 3/4 ton equipment (more akin to 1/2 ton hardware). Lots of misinformation out there, especially by junk yard workers on the telephone who don't know what they're selling or the difference b/n them, so they list applications as 3/4 ton AND 1 ton ...big red flag. So make sure you see pics if you're sourcing used parts remotely. Another benefit of hunting for a Dually setup - those were all JL8.
