How high can I go with out going to a longer drive shaft?

 

you wont have to change the driveshaft if you do:
torsion bars
body lift
2" suspension

....wait you talking rear or front driveshaft?

i have 6" susp wth no otehr bull**** body lift or torsion lift.

the rear driveshaft is fine, always has been. The FRONT however ive had issues, with, GM made a ****y design, and therefore it doesnt like the changed angle with the lift, IVE BROKEN 3 DRIVESHAFTS, 2 at pismo, 1 in the mountains.

and you cant just change the driveshaft or get a longer one, if your going to put money into it, its about $500 to change stuff in transfercase so you can get double cardan setup.

 

Hey, watch the language!

And if GM made such a crappy design, why do they predominantly break when combined with aftermarket lifts?

 

not trying to be rude, but gm designed the blazer/jimmy/s10 ect driveshafts as a simple driveshafts for only at stock height, they do fine at stock height as long as they are not put under too much stress.

Full size trucks like silverado or F250, or almost any otehr truck or suv, uses a more sturdier, beefier driveshaft with the "stadard" design of either ujoints at both ends, such as something like a double cardan setup,
because of that, their driveshafts still work when their angle is changed with lift.
...the s10's dont quite work that way,
