So assuming you're doing a dually conversion to your 1500?

8 lug (whether 2500 or 3500) spindles don't directly bolt to 1500 control arms, upper ball joint is different. You could redrill the bolt pattern for the ball joint but since the 2500-3500 upper arms are better (forged) just swap to those. They bolt right onto the frame.

8 lug rear axle bolts right in as leaf spring width is same 1500-2500-3500 but what you have to decide is how you're going to solve the width issue. Semis won't fit between the dually fenders without changing something; some run a chassis cab rear because it's narrower but that will involve some other work as the width between spring packs is narrower, or some widen the dually fenders, etc. What kind of suspension setup you plan to run will come into play too, bagged, static, lifted, whatever.

So to put 8 lug front assembly on my c1500 I would have to Redroll the bolt holes ? I've got the 8 lug 14 bolt ready to go in. I want my front to be 8 as well.

Just grab the forged uppers from the 8 lug truck. They bolt right in, as I said, and you won't have to battle with drilling out ball joint holes to run the correct ball joints to fit your spindle. Of course we're assuming a bit here as this is your first post and you didn't provide much detail.

If he cannot find ones on a truck, the 96-02 van ones are the same too.

Yes sorry this is my first post. I just found out about this place.i have a c1500 6.0 4l80e with a 8 lug 14bolt rear end. I have yet to fund the drive shaft. And the front suspension. Just didn't want to have it Harder than it should be. All I want is my front to be 8 lug like my rear end swap Thanks and sorry for the late reply.
