Eff One Fifty, did you raise your rear up when you cranked your coilovers?

 

the body lift is a huge pain...it took us about 12 hours to put one on my buddy 2005 f150 ext. cab...i would recommend the 6" suspension or just the leveling kit...we are not professionals so it may not take you that long but it was a huge pain

 

Always have your suspension checked every 10k miles. Its a safety precaution. It might cost $80.00 but its alot less than your deductible and you get to drive your truck instead of visiting it at the local bodyshop.
