• 2004 GMC Sierra Buildup Mcgaughys Shocks
    In went the new McGaughy's shocks. You can also see, the old, crusty tie-rod ends that were reused. Don't worry, we're also going to replace those and the ball joints, just not on this day.

  • 2004 GMC Sierra Buildup Hotchkis Sway Bar
    Marcel and I were now ready for the new 17⁄16-inch Hotchkis sway bar. This bar is serious and included really nice greasable bushing mounts and burly new endlinks.

  • 2004 GMC Sierra Buildup C Notch Marked
    Out back, I had cut out and installed the McGaughy's C-notch on the passenger-side, but ran out of time to handle the driver-side. Thankfully, former Sport Truck editor Mike Finnegan arrived and we quickly put him to work. First, he placed the notch onto the frame and marked the "C" with a scratch awl.

    With the lines marked, he drilled two large holes on each corner (these will enable a horizontal cut with the saw).

    A Sawzall was then used to cut the frame away and a disc grinder cleaned up the rough edges and trimmed any excess.

    Each supplied bolt was then torqued to spec and the new polyurethane bumpstop installed.
  • 2004 GMC Sierra Buildup Axle U Bolt Nuts Removed
    Keeping with the rear suspension install, each axle U-bolt nut was removed thanks to a breaker bar. To gain access to the driver-side leaf spring bolt, the gas tank had to be lowered down and swung over. This sounds more difficult than it is and two 15mm bolts hold the straps in place. Thankfully, we had less than a quarter of a tank of gas.

    A 13/16-inch wrench was then used to remove the leaf spring bolts, which allowed for the leaf springs to be pulled free. The new Hotchkis 4-inch drop leaf springs were then bolted on using a 2-inch drop shackle from McGaughy's.

    Helping the truck really handle front to back, we ordered a rear sway bar from Hotchkis. The sway bar came complete with axle clamps, heavy-duty dog bones, and greaseable bushing mounts.

  • 2004 GMC Sierra Buildup Dog Bone Mount
    Step one was to loosely hang the sway bar from the axle and find the proper positioning of the dog bone mount. With the position marked, we drilled two holes in the frame and installed the mount using the supplied bolt bracket and hardware.

    The dog bones were then bolted into place using Grade-10 hardware. Thankfully, we already had the gas tank lowered on the driver-side, so we had access to the inside of the frame for the driver-side mount.

    Finally, after a long day of testing and wrenching, we were ready to bolt on the new wheels and tires—in this case BMF Novakanes, sized 20x9 inches and Nitto NT05 275/40R20 tires. This combo look sinister and race-ready, a combination not easily achieved for a performance truck.

  • 2004 GMC Sierra Buildup Brake Problem
    With the jackstands removed and the truck on its new suspension/wheels and tires for the first time, we had our only problem—the wheels wouldn't turn. Come to find out, the McGaughy's spindles had slightly different locations for the brake caliper mounting tabs. Because of this, the AP Racing calipers were rubbing the rotor surfaces and locking up. After a failed grinding attempt in the dark, (sorry Brandan), we called a flatbed and went home bummed out.
