Spacers only on my front end????

[iSportsman]

I purchased a zone 6.5" lift new 20" gmc reps. The lift called for a 6" offset for the front to clear. My rims were 5.75" so they added 1/4" spacer to make up the difference. But didn't add them to the rear. Is this an issue? I'm experiencing drift when above 45mph. If I add them to the back will this help the sway?

Yeah that is caused from the new increased track width with that lift kit. The rear needs 1.5-1.75" spacers to true it up. Think 1.75 doesn't require any cutting. I know the zone increase 1.5" front plus your 1/4". Not much you can do to fix the front end tracking. My Denali feels weird after driving a normal car. Just takes some getting used too
