Raise the rear of the vehicle enough that you can slide in from the back all the way to the fuel tank. I used ramps for this as it provided me more ground clearance and was far quicker and easier.
If you have a Cruze Eco, you'll have a deflector that will be in the way. Remove the 10mm plastic nuts holding the deflector on. There should be 6 nuts.
Next, locate and remove the center and rear-most bolts on the rear axle brackets.
Fit the UR lower bar over where the bolts were removed, and lightly thread the bolts back in.
Tighten the bolts to 66lb-ft + 45 degrees (about 1/8 of a turn). A breaker bar makes this easier. That's it!
If you have a Cruze Eco, re-fit the deflector, lightly tightening the plastic nuts (they will strip easily and don't need to be very tight).
To complement this rear lower bar, be sure to check out the Ultra Racing front strut tower bar and rear strut tower bar as well. Both will improve handling through chassis rigidity, ride stability, and ride comfort.
