14bff from van or pickup?

[ChickenRammit]

is there any advantages to getting a 14bff from a van? i heard they are wider than the ones from the pickups. would the spring perches need to be relocated?

 

[mechted]

yeah, spring and shock mounts require relocation if using a Van (P series) 14bff

if you pull one from a K20 it will bolt right on, if K30 than spring and shocks mounts need to be moved.

IF you pull one from a C20 (2wd) then the shock mounts may require modification (they hang lower/ cause interference when flexed), but the spring pads are good to go

is it true that the 14bff from a van is wider that that of a pickup?

I was wondering the same,If it was wider,how much wider it is,and would it be wide enough to run duals???Theres one here at the bone yard in a 90 3500 van.

yes, they are about 3 inches wider.

Van width rear on my blazer. It is now even with my front. Normal 14ff's are not as wide.

so basically, if i get a 14bff from a van, it will be the same width as a d60 front with srw hubs? are the spring mounts and shock mounts the same on a van as on a k5?

p.s. the pic you submitted answered exactly where i was going with this thread.

I have a SRW chevy d60. Van width 14ff. The rear perches and everything where not on it when i got it, so it was all replaced. But the 60 and 14 are just about even, or atleast very close. And i have 15x10 rims with 2.5" of backspacing. thats why they stick out that far....

perch locations:

1/2 & 3/4 ton trucks = 42.5

1ton trucks = 40.5

van axles = wider yet. iirc 49 wide.

shock mounts:

1/2 & 3/4 ton trucks = same except 2x4 3/4 ton diffrent.

1ton trucks = same positions 1 ton only.

van axles = van position only.
