Question:
Hey, I have a 2003 GMC Sonoma ZR2. The kit says its for 2wd. Why dont the kit work with my 4wd truck? Can I just use spacers or it there more to it? Thanks

Expert Reply:
Hey Nick, the suspension between the 2WD and the 4WD versions of the 2003 Chevy S-10 is more than just additional ride height. The 4WD versions have disc brakes whereas 2WD has drum. The rear shocks are longer to accommodate wider tire widths. The 4WD models also have longer axles. So what that means is that the air bag kits just don't fit in the area on the vehicle so you'd need to go a different route like with the Hellwig part # HE72FR.
