Thanks what size of rear axle and springs K20 or K30 or what

[FordeatinZ71]

well, you can get a 14b FF (Full Floating) rear axle from any 20-30 series truck. it can even be a 2wd since your 8-lug bolt patterns are the same...

[GreaseDog]

for a 1/2 ton with a 14FF transplant, go for a 20 series truck or Suburban, as it's a bolt in deal. the 30 series trucks have a narrower spring pad width. if you find one with both front and rear axles intact and matching, the front will be almost identical to your current front axle, if not identical (10 bolt front and Dana 44s are comparable in strength.)

[Ivan D.]

GD, did the K30s have a Dana 44 in the front? Why so light-duty, when both Ford and Dodge got the Dana 60 front?

[Chevyforlife502]

so a dana 60 are ford or dodge eh

[44gmcnewf]

gm put dana 44 on 3/4 ton trucks and had dana 60's 1 ton trucks

[Chevyforlife502]

will the ford and dodge axles fit

[GreaseDog]

the 77.5-79 Ford axles will fit but will require a drivers side drop transfer case, and the Dodge axles will be able to use a stock passenger side drop transfer case, the spring spacing on the Dodges are about 1/2" off, but you can make the springs fit just fine.

[Chevyforlife502]

so the dodge don't need anythink to fit them

[GreaseDog]

nothing as far as parts, just squeeze the springs together to fit into the perches, and bolt it up. there are a bunch of guys running around with Dodge 60s in Chevys. squeezing them together is easier with taller springs too, as they dont have to pivot as far at the bushing.

[Chevyforlife502]

sweet thanks man so I will need at least k20 if not k 30 spring to do the 5.9L swap? Also will any other spring work thanks

[Chevyforlife502]

Puls what other axle will work for the rear

[GreaseDog]

i would look into custom springs, Deavers, Nationals, or Alcans seem to be the most popular.

for the rear, a 14FF will do just fine.

[Chevyforlife502]

do you possibly have a link for those places thanks man

what about a rear axle for the my truck will a dodge axle work for the. Pretty much dodge drivetrain chevy everything else.

[Ivan D.]

He already answered that question - get a 14-bolt full-floater off a 1-ton Chevy/GMC, tis quite possibly the strongest readily-available axle for a pickup truck.

yep, one of the strongest axles you can get next to a Rockwell...and it bolts right in...can't beat that with a stick...

[1974ChevymediC]

no, you want one out of a 3/4 ton if you want a direct bolt in to a 1/2 ton truck.
