2004 Infiniti QX56 - The Height Of Luxury

The first piece of new hardware in the rear, auto-leveling drop brackets, was placed in the factory mounting location.

A bumpstop drop bracket was sandwiched between the auto-leveling drop bracket and rear suspension spacer. The spacer was bolted onto the frame by using the same mounting locations as the rear suspension assembly.

On the opposite side, Jesse drilled a hole into the factory bumpstop mount to bolt in the drop bracket.

After holes had been drillled, the three pieces on each side were bolted together.

Reinforced arms and mounting tabs provided additional mounting points from the rear suspension to the spacer.

Jesse drilled holes through the rear suspension assembly after it was fully lifted into position.

Mounting the shock brackets was actually a little tricky, since each side was similar, but not interchangeable. This is the proper orientation.

The shocks will mount onto the lower control arms and provide additional damping to compensate for the additional mass of the larger tires. Jesse marked and drilled the holes on each side.

Bolted securely in place, the shock mounts are definitely strong enough to handle the load.

Brian returned to the compressor where he marked and cut the bracket as directed by the instructions.

Pro Comp included drop brackets for the compressor, which were bolted on by using supplied hardware.

Here's the finished rear suspension, complete with braided stainless steel brake lines, bumpstops, and MX6 shocks.

Wrapping up the loose ends, the evaporation canister was secured with extended mounting brackets.

Finally, the safety strap, which was a steel cable in our pre-production model, differed from the production version that the suspension was based on. The x-shaped bracket was cut in half, then widened 3/4-inch with a 3/16-inch plate before being welded, painted, and bolted in place.
