Check your strut angle first!!!
I have an 05 F150 4WD (which said would fit) and because the top of the strut is angled, this would not work because it flips the bolt pattern backwards and you cannot just flip the strut to compensate. My father has an 07 F150 2WD and the strut towers are straight instead of angled. Installing this leveling spacer was a breeze but the bolt pattern is now reversed. To solve this issue, just rotate the strut 180degrees and your bolt pattern will mate perfectly. Truck looks level, no longer raked.
Firestone air bags
Great product with quality instructions. Every thing fit very well on truck. Taking off the old bumpers on frame over the axle can be very challenging to say the least, but once that is done installation is a breeze.I found these by far the best price using one of the discount codes.
