3/4 Ton of fun - ‘95 Sierra

[Road Trip]

Mmmmm I don’t think so. I think it’s more of a drivetrain thing. @Road Trip has a C2500 with a 454 and has a FF. I’ve seen other Vortec trucks with SF.

Pulling the center cap on a FF and the first things you observe are the 8 bolts attaching the axle
inside the 8-lugger wheel studs. (See attached.) On the 8600 GVWR C2500s it's thought that
the big block was what tipped the scale for a FF to be installed at the factory?

And for what it's worth this is what it looked like to do the brakes on the FF version of your rear axle.
(JD7 rear brakes on a FF)

Enjoy the 8-lugger experience. It's the understressed way to be. :0)
