I just got a 1989 k5 blazer with a 4 inch suspension lift and a 3 inch body lift. it has a longer rear drive shaft and a stock front drive shaft. the paerson i got it from said i need to get a longer drive shaft for the front. is that true? with only a 4 inch suspension do i need a longer front drive shaft?
:confused: :confused:
 
Can you bolt the shaft in? Are you going to go offroad with it?
If I remember right, at 4" lift, you will max out the front driveshaft at full droop pretty easy.
 
With a 4" you are marginal.

You can use the stocker and will be fine except at full droop out situation.

On my old Blazer it had a 4" Rough Country lift and I drove it for like 2 years problem free, with some mild wheeling.

Since you went with a BL also you prolly have larger tires which will also help some as it raises the PY centerline closer to the TC.

I vote try it and see what happens
 
I had a 203 in my old 79. I ended up putting on a 6" Suspension lift and didn't really have any problems with the Drive shaft at full droop. I just put a 6" suspension on my K10 yesterday and I have about 2" of shaft to play with. They springs are really stiff so not really worried about it for the pickup. It will depend on how soft your springs are. It would be safer to go ahead and have it extended a few inches. Also deoends on what T case your running as to how much of the splines are left in the shaft at full droop.
 
when i had my 85 k5, i had skyjacker 4" front springs and no problems with the front driveshaft... 700r4 tranny and np208 tc
 
Is the t-case dropped?
 
Unless you don't want to lose the extra clearance, lowering the transfer case is a decent alternative.
 
I ran the stock front shaft in my 78 k5 for two years with a four inch lift and had no problems on the trails. But than again I also hit a big dip on the interstate at speed and it fell apart, and that was in 2wd.
