How difficult??

Hello folks. I got a buddy wanting to get rid of a ford 9" rearend for nearly nothing. This will be going in a 85 swb gmc truck. I was wondering what all is involved in making a swap like this happen? I keep hearing about tapered axels and shortening and this and that, and have been reading on it but still dont know what all this means??? i want my truck to look like this one when it gets finished with the large tires tucked in under the fenders. What would i have to do to achieve this look?

no problem

If your going with a 4-link or ladder bar set up you will just need to make shure that the rear end is within 4 inches of the stock rear end width so it will fit under your truck. if your going with leaf springs you will just need to cut the spring mounts off your trucks rear end and weld them on the 9". if it will be a drag truck them i would make shure that your buddies rear end dousn't have 28 spline axles it will only hold at max 400HP.

if i were you i would look around a junk yard for a GM 14 Bolt rear end. you can find them in late 90's- early 2000's Chevy Z-71 and are redly available for cheap. did i mention there stronger then the strongest 9-Inch. plus then you keep it all chev. the 14 bolts Ring & pinion gear in only a tad smaller then a funny cars. on the down side there about 25 Pounds Heavier then the 9".

I also hear that th GM 8.5 10 bolt is about as strong as a 12 bolt and can be made "Bullit proof" for about 750 bucks, if your on a budget. the 9inch will cost you at least 1000 bucks to make it strong unless its already a 31 spline axle car. before you buy it count the axle splines.

get back to me to tell me what your plan is,

Sorry for being late on the reply I have been out of town working for the last 2 weeks. I got a spare gm 12 bolt already with posi trac and everything. But i was told that wouldnt hold up to the 800 or so hp this supercharged 383 is supposed to be putting out.

I'm just curious about WHICH 14-bolt axle is being talked about, the 9.5 inch semi-floater, or the 10.5 inch full floater, I haven't yet seen the newer 11.5 inch so I am unsure about the cover bolt count.

They are all adequate for the power output, but with the cost involed to narrow might equal the total cost of a fabricated 9 inch when you are done.
