I noticed that people wanted to raise their titan/h2 bodies, which is different than raising the f150
What you'll need:
A screw driver
A nut driver
3 LONG screws(not shown)
9 2-56 hex nuts from radioshack(they come in a pack of 40 and can be used as wheel nuts as well)
and yes the little boy in the pic is me when i was young
first you flip the front clip(for the people who want details. stock height of body from ground to fender is 3.8cm with off road kit tires with stock towers/arms, and flipping it raises the front up from 3.8cm to 4.3cm)
now take the rear clip off the titan and put long screws in the holes then put 3 nuts and screw them to the top on each screw like i did(3 nuts = .5cm)
now screw everything back on then put on your body
now for the hummer do the same thing but use 2 nuts on each screw instead of 3).
Enjoy
