Ask Bob .... I don't want to use wheel spacers ...
Converting your old pickup over to the S10 requires using a 4WD axle in the rear. The Ford 9 inch and Ford 8.8 both work as well. But what about the front? Custom Offset Rims? You can have custom rims made where the offset brings the wheel out further, but you should always consult the wheel manufacturer before simply ordering a set of offset wheels.
We recommend using 1 1/2 inch billet aluminum wheel spacers. There is another option, however, for those who do not enjoy running wheel spacers and already have non offset rims. Fatman Fabrications G-Tech custom Controls arms. These can be made from 1" narrowed to 3" extended. If you have the $$, and do not want to run a spacer, give Fatman Fab a call and ask them about thier Custom Control arms for the S10 Chassis.
