Like alot of you guys kno, i'm having issues fitting my 10.5 rim becasue i have the wrong offest....but would a 1inch spacer be alrite to do?? would it be weak, or snap after awhile? any input helps
If you don't need them then don't run them. If you do then keep it small. A 1" spacer is too big to run safely. Run the hubcentric ones, don't use the ones that have studs built into them. Run longer wheel studs if necessary so you can still have the lug nuts tighten down enough.
i ran 1 inch spacers on yukes car and never had a problem. they had the studs built in.. i would take the wheels off and torque them down like every 6 weeks though, but they were never any looser
car had 3.90s too if that makes a difference

1996 f150 extended 4x4... 6 inch lift on 35s... sold
what is so bad about them... they bolt on like a wheel and the wheel bolts on to that... more rotating mass? i guess if you were pushing serious power through them id see a problem but what are the downsides if you keep them tight and check them regularly?

I run 3/8" w/o issue as do a large amount of IRS cobra owners w/ 17x10.5's. We need them to clear an IRS bolt and the IRS subframe. Its different on a solid axle. There really is nothing wrong w/ a small spacer if you get a quality made one. The guys running a 1" are the ones with something to worry about. If you don't need them dont' run them. If you do then run the smallest hubcentric you can with some good upgraded wheel studs, even if they are the stock length.

It depends on the spacer. Not all spacers are designed the same created equal.
Basically the issue is shearing the lugs. If the spacer is of poor quality and there is slop, you can shear your lugs off and lose a wheel. Basically it's leverage. The father away from the hub the wheel is, the more force acts on the lug at the point where it emerges from the hub.
Basically i'm gonna get into a bunch of mumbo jumbo about shear stresses and moment arms and etc. (I'm an ME)
To make a long story short, best spacers to use are the bolt on type and hubcentric and keep them properly torqued at all times. And like i said, upgrade your lugs too.

scrib those ones are hubcentric i beleive, and bolt on, so there pretty safe, its when u get into those lug centric ones like the 1/2" ones i had on the ranger way back that arent good
i dont think you should need 1inch spacers with wheels that are made for 94-04 cars. i run 3/8 spacers on the front of my car but i also have 3inch studs too. take out the quad shocks and call it a day
