2010 Gmc Sierra 1500 After

From the Driver Seat
After installing the DJM lowering kit, the truck has a better stance and thanks to the sway bars, the truck's cornering was greatly improved. Before and after the install, the truck was run through a 600-foot slalom course. Before the upgraded suspension the maximum speed was 52.76 mph. After the suspension install, the slalom speed increased to 55.1 mph. This is due to a lower center of gravity, the upgraded front sway bar, and the new rear antisway bar. The mpg have also increased, up 1.5 mpg, thanks to the intake and exhaust upgrades. Whereas the used wheels and tires are OK for now and did help keep the initial cost down, we'll be upgrading them soon to squeeze even more performance out of our DJM suspension. Stay tuned for that and the rear airbag install.
