10bolt to 14 bolt swap help

[Wagonbacker9]

Conversion u-joint, or keep the yoke off your 10 bolt. Either will get the job done.

So the yokes from the 14 bolt sf and the 10 bolt are the same or interchangeable?

 

[TylerZ281500]

interchangeable. 14 bolt is liekly a 1350 and a 10 bolt rear ujoint is a 3r. i swapped my rear weld yokes on my drivehsaft instead of messing with conversion ujoints.

interchangable on the pinion.

 

[TylerZ281500]

pinion yokes yes, only difference is the 10 bolt u joint is a 3r and the 14 bolt uses a 1350. i wouldnt run a conversion u joint because they are actually weaker than an actual 1350 or 1310 etc.

Yes. You will need the u bolt plates and new u bolts for a sf 14 bolt. The 10 bolt stuff wont fit.

I am doing the same swap right now in having issues on getting the parking brake cables hooked up are the cables the same from a 10 bolt to a 14 bolt

1) If you want to use 4wd then yes, your gear ratios should match
2) You will need u-bolt plates from a 14 bolt because the axle tube is bigger, also you can swap yokes from your 10 bolt or use a conversion u-joint. Steel driveshaft needs a precision 447, aluminum one-piece driveshaft uses precision 448.
3) 14 bolt sf axle out of a 4wd OBS truck, u-bolt plates or u-bolt flip kit, conversion u-joint (if you choose to go this route) This was the information I need today. Thanks.
